Schumacher (1) Selecting a value will reload the page Scosche (32) Selecting a value will reload the page Scotchgard (1) Finally, upon reaching some programmed end point, they stop charging. LOL. We will see how it does. It also does desulphation, which will ruin a battery that has had too many charging cycles from almost drained condition to fully charged. I put the battery on the bigger 55-10-2 amp charger and within a few hours it said fully charged. about 60 bucks on sale but does it all. Most of the 'smart chargers' measure the voltage of any battery you hook up, and if its very low, say below about 8 or 9 volts, the charger/maintainer gives up. Schumacher SC1281 100 Amp 30 Amp 6V/12V Fully Automatic Smart Battery Charger. The Products We didn’t attempt to test every single product on the market billed as a battery maintainer. We give a very slight edge to the Yuasa 1.5 for its 28-day battery exercise cycle, but all of these units are excellent performers. We know, from our six-part electrical series in previous issues of Wing World, that discharge creates sulfate crystals on the battery plates. They were observed to perform extremely close to their manufacturer’s specifications. It tapered the charge rate as the battery approached 14.3 volts, finally holding the battery at 14.3 while the absorption rate dropped to 0.3 amps. I guess this leads me to believe the cheap charger really never fully charged the battery and the bike is not charging it either. Does anyone remember what it was like before the internet. When viewing the current waveforms in this article, the reader will notice evenly spaced downward spikes. the battery tender i have will charge a battery........ i guess there are just maintainers out there...that will not charge. I would stay away from "float" chargers. Looking at the shape of the current pulses, it can be seen that they are not as abrupt or as great in amplitude as with the AccuMate. Other bikes with ABS or fuel injection also have improved electrical output potential because the computers for these devices must never be starved for voltage. The SP3 came with the proper style connectors and several others. A 4-amp load across the battery terminals instantly caused the start of a new charge cycle. During float, the Yuasa 1.5 maintained a 10-milliamp current and kept the battery at 13.29 volts. Another cure is to ride the machine often and at high enough revs to ensure thorough battery charging. Battery Tender Junior Charger and Maintainer: Automatic 12V Powersports Battery Charger and Maintainer for Motorcycle, ATVs, and More - Smart 12 Volt, 750mA Battery Float Chargers - 021-0123 4.8 out of 5 stars 24,693 But from my experince with the AGMs, they are a huge improvement over wet cells. SBT-CHGWP-80-11” Reviews “Schumacher SE-3000 Manual Fleet Battery Charger” Best Sale They all held the battery during float at what most books we’ve read on the subject consider to be proper at the test temperature. It is designed to keep a good battery at it's peak. Keep in mind however that a typical system doesn't provide juice below 2000 rpm usually. It’s billed as a five-stage charger/maintainer. Current pulses peaked at 4.4 amps during charge and ranged from zero to 2.2 amps during float. More on that later. If it has been that deeply discharged it will take a while to bring it back up, and that is a chance it may not come back to full power. I only use the tender when the bike will sit for weeks or more. Float mode monitoring automatically maintains optimum battery charge. This final stage of operation exercises the battery, providing additional protection from sulfation damage for batteries stored for extended periods. We actually had to go to rallies to learn all this stuff. Funny thing about all this is that I'm still looking for that bike that meet or lives up to the 88 venture I been riding for the last 20 years. We have no way of knowing the algorithm used, but a program which caused the unit to assume a certain temperature differential based on its own internal temperature would be the highest level of sophistication we’d expect to see at this price level. Still, the Battery Tender Plus from Deltran Corporation was surprising to us in its inability to recharge a depleted battery with the speed of the other products in this group. Case in point: The Battery Tender Plus, a charger and maintainer that also ranked as best overall on Roadshow's list of top chargers. SUNER POWER Solar Battery Maintainer In the float (maintenance) mode, of the three Battery Tender examples tested, one simply allowed the battery to slowly discharge to around 12.4 volts. Good smart chargers cost more and will do it all... Jack is right. Sadly, many other bikes of recent or current manufacture, including the GL1500, are no more capable in the electron department, especially during slow riding, than those models of the mid to late ’70s. It started right up. As with the AccuMate, placing a load on the battery activated the charge cycle once again. While Deltran claims that the charge and float voltage is a function of the temperature compensation feature of the product, we believe that 13.2 to 13.4 volts would be a more appropriate float voltage for the 70-degree temperatures at test time. Then the units are supposed to switch to what’s called an absorption mode in which the battery can soak up the last bit of charge at a natural absorption rate that won’t result in excess gassing or heat. The Power Grab In 1976, daytime headlamp laws became universally mandated in the United States. Put an old fashioned simple charger on it and it eventually charges it up... " each and every deltran Battery Tender will , regardless of it's size , charge a battery and maintain it". As a plus, the Schumacher has a LED display that tells you what the charger is doing. If it isn't doing so something is wrong with it. Many riders simply ignore the issue and buy a new battery in the spring. Conclusions And Recommendations We chose to test the units at room temperature to verify their manufacturer’s claimed performance, and relative to one another rather than to some industry standard for motorcycle battery chargers (if such a standard exists). When first connected and plugged in, it flashes lights to signify correct polarity and the presence of AC power. It does everything a 'Battery Tender jr" brand maintainer does, and additionally puts out 1.5 amps rather than just .75 amps of the Battery Tender jr, as well as detecting and charging 6 or 12 volt batteries, while the Battery Tender … Schumacher 1.5 Amp Battery Companion The Schumacher is a fairly new entry into this market. Though the original Battery Tender was the first commonly available inexpensive charger of this type—a unit that can be left connected without fear of overcharging—competition in this market has grown considerably. A tender or maintainer provides automatic operation and less than a trickle charge. However, since a battery maintainer can be left connected to a battery indefinitely (with precautions described later), a single hookup in late fall should insure a good battery come springtime. The charge rate continued to drop dramatically, and the rate of voltage rise slowed just as dramatically. Unlike the larger Yuasa, this charger didn’t exhibit a clear transition from bulk charge to absorption. The voltage is then maintained at 14.3 while the battery absorbs charge at its own natural rate. There are also some junk units that may do more harm than good. I have not checked the specs on this maurader but as dissapointing as it is, I do believe it. A product that doesn’t quite make the grade here may be more than adequate on smaller batteries, while more powerful units may be required to do a quick and thorough job on large automobile batteries. This a little off topic but I think this was a better place to post rather than starting a new thread. That seemed to be the case until we hooked the Tender to a battery that had just been charged with one of the competitors in this test. This on again, off again float cycle repeated each time the battery dropped to 13.24 volts. Features 30A quick boost and 1H2:L1600A jump start, powerful enough to start SUVs, trucks and large batteries. NOCO Genius G3500 6V/12V 3.5 Amp Battery Charger and Maintainer.

I'll bring it in again and have it load tested and see what happens. It is safe to leave a battery maintainer connected to your battery all the time. that bike had an alternator that should handle electric clothing. 2002 vz800 maurader and it lost its charge. I have an AGM ETX12 battery in one of my bikes. But a 20 minute ride isn't going to be enough to bring the AGM back to fully charged from 70%. Instead, we sampled five of the most popular and readily available products, believing these most likely to be purchased by our readers. That didn’t happen with the first example we tested. “NOCO Genius G26000 12V/24V 26000mA Fully Automatic Battery Charger and Maintainer (Grey)” Hot Deals “Leviton EVB32-8ML Evr-20 7.7 Kilowatt Charging Station with 18-Foot Cable” Price “Yamaha OEM Battery Tender Waterproof 800. A battery supplied with a constant current and held at an unwavering voltage that’s less than the gassing voltage will begin to sulfate after 60 days or so. I'm learning more all the time from these groups. The shop owner said (do I believe him?) I swaped out a honda CBX alternator for a newer one off a zx10 or something and it is way better but I think it would be a different story on this bike. Energy efficient, meets the highest industry standards. These result from electromagnetic interference due to the 60Hz, 120VAC electricity coursing through the building’s wiring. The Yuasa 1.5, the AccuMate, and the Schumacher all performed very well in these tests. This battery tender does an excellent job of maintaining my battery. It uses very little current. This is to protect the charger and the battery, in case you have hooked up a battery with a shorted cell or two, or something like a 6 volt battery. The auto parts store manager pointed out something I was unaware of and wanted some more opinions on the subject. We therefore conclude that like the other units in this test, the absorption mode terminates when the battery’s current acceptance rate falls below a certain level. Likewise, trickle chargers put out a constant charge regardless of battery voltage and can seriously overcharge if left unattended for extended periods. The Tender kept charging hours longer than the others before attaining 14.4 volts across the battery terminals. It was so primitive. That’s not an issue if storage was your reason for attaching the Tender. #1 Home Improvement Retailer ... Schumacher 12-Volt Solar Battery Maintainer Model# SP-200 View the RV Gadgets and Gear $ 27 04 $ 27 04. Funny she says that about me too. In this article, keep in mind that we tested these products on batteries the size and capacity of those owned by most Wing World readers. After about six hours in the absorption mode, the unit stopped charging. the more the battery has to share with eeeevvvvrrreeyboddyyyyyy. Battery Maintainers Versus Battery Chargers Most automotive-type battery chargers can attain an output voltage of more than 17 volts if left connected too long, and this will cook the electrolyte out of a battery. If the battery isn’t returned to a state of full charge, the crystals will harden, become permanent, and will shortly render the battery useless. What is everyone elses opinion on this matter. The unit then applies a series of pulsing currents while monitoring the rate of voltage increase and decay. Its manufacturer claims it will charge at 1.2 amps constant current until the battery reaches 14.3 volts. Some chargers may incorporate the features of a maintainer while others may not. Seasonal storage of batteries is a challenge to many new motorcyclists.

The Battery Companion from Schumacher is a very cost-effective way to charge a motorcycle battery and hold it in float for periods of 60 days or less. As can be seen on the accompanying graph, the pulsating float current is applied at 13.24 volts and discontinued as the voltage rises to 13.56. When the Schumacher was first turned on, it began charging the battery at 1.65 amps, exceeding its rated maximum. The cheaper alternative to the Battery Tender above is the … Lastly, the maintainer should be able to hold the battery at a post-charge voltage that will neither cook out its contents nor allow it to self-discharge. When it gets battery to where it should be it stops til battery needs to be brought back up to full charge. As a fifth and final stage, this unit claims to shut down, then re-start the charging process every 28 days. Secondly, since many bike batteries have been in a state of partial discharge prior to charging, the maintainer should have the capability of breaking up slightly hardened sulfate crystals and discouraging their formation. The float cycle is interesting in that it has features that discourage sulfation and exercise the battery as well. At that time, the charge current pulses quickly flattened away while charging continued to 14.44 volts. This battery maintainer makes it at the … To view the performance of these units while charging, we used a digital storage oscilloscope sampling at five million samples per second and capable of displaying “events” as short as two millionths of a second in duration. Pick up at any of 500+ stores. They will put a charge in but I do think it would take days. The unit did indeed switch back into charge mode when a load was applied to the battery. Your bike's charging system should keep your battery charged. The main detail to remember is that a battery charger typically sends a constant charge to the battery, with no regard to whether it actually needs to continue being charged. October 18, 2011 in Watering Hole. The Schumacher had no problem at all charging the battery back to 100%. This solar battery maintainer offers great value for money, and is suitable for 12 Volt lead-acid batteries. It may not even be able to do it at all. They all achieved gassing voltage and then some. Like its larger sibling, it has multi-colored LEDs that indicate power, polarity, and charge. For some reason you can ruin these with a regular charger. Keeping these machines plugged into a battery maintainer when not in use is one cure for the electrical deficit spending. + Update your shipping location ... CTEK MXS 5.0 12 Volt 4.3 AMP Car Battery Automatic Charger Maintainer & Tender. The current waveform taken at 12.75 battery volts showed the current still slightly above manufacturer specs, though it had dropped noticeably in a very short time. Though maximum output is claimed to be 1.5 amps, there’s no indication at what voltage the current will begin to drop off. Though we attempted to be as consistent in our testing as humanly possible, given our lack of laboratory grade equipment, we readily admit that the number of amp hours drained from the battery before each product test was not identical in each instance. However, a loose alternator belt, faulty alternator, or a dome light left on overnight could result in a discharged battery. They are not good for batteries that are on their last breath. At 14.0 volts, the charge rate was down to 0.425 amps, but the unit did manage to charge the battery to a terminal voltage of 14.48 volts. Most batteries that become useless over the winter suffer at the hands of well-intended owners who simply forget how long ago it was that they last shoveled their way out to the garage to monitor their battery charger.

Battery Maintainer vs Battery Charger A lot of people aren’t sure what makes a battery maintainer — which is also called a battery maintainer — different from a charger. The manufacturer warns not to leave the unit hooked to a battery while it’s unplugged from AC power. The current tapered at 14.3 volts, and this was accomplished by reducing the pulse heights while retaining their shapes. You need to be a member in order to leave a comment. The relatively small size of most motorcycle batteries and alternators creates other problems as well. We had been told by one informed source that the Tender was programmed to charge to 14.4 volts, then hold the battery there for around six hours for a thorough charge. The maximum average charge current noted was 1.25 amps, so the output exceeded the manufacturer’s claims in that regard.

One achieved 14.1 volts before “floating.” The other went to 14.4 volts, but both required significantly longer than the other products to reach that level. Self-discharge is a phenomenon in batteries where inward concoction responses lessen the putaway charge of the battery with no association between the anodes or any outer circuit. Battery tender give you a choice of either a 5W, 10W, or 15W solar panel solution, so the one you choose will depend on the power demands of your battery. Most of the 'smart chargers' measure the voltage of any battery you hook up, and if its very low, say below about 8 or 9 volts, the charger/maintainer gives up. Top Rated Seller Top Rated Seller. The GL1800’s alternator has the capacity to keep its battery from discharging at all engine speeds. Battery and alternator tester provides charge level and helps diagnose electrical problems. When the Tender was first turned on with battery voltage at 12.5, the unit began charging at 1.34 amps. But based on the existing loads and charge output of the average Gold Wing, we’d prefer to completely recharge the battery before riding off.
