Hi all: I want a charger for my car that sits idle a good deal of the winter months in the garage. This ‘Plus’ model provides 50% more power than the BATTERY TENDER® Junior model, making it suitable for larger vehicles with a heaver voltage draw. For bench testing electronics, use a regulated power supply. From these discussions, we’re hoping you’ll start to understand what a high-quality example of these products might look like from a customer’s perspective. I've never needed to use a Tender on it at all. I would stay away from "float" chargers. The smaller the battery, the quicker the damage will occur. 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. All of the other brands tested here, after being subjected to a 4-amp load, completed a charge to around 14.4 volts before reverting to float. I own a Battery Tender, a Schumacher (1.5A), and a Yuasa Smartshot (1.5A). The charger ramped up its output until the load was removed. $27.12. Unlike the larger Yuasa, this charger didn’t exhibit a clear transition from bulk charge to absorption. Maximum voltage during charge was 14.4 volts. The fully automatic Battery Tender 1.25 Amp battery charger and maintainer is a top-of-the-line 12V battery charger, perfect for motorcycles, ATVs, dirt bikes and other powersports vehicles. In some cases, quite far. I buy a new battery around that timeframe, needed or not. It started every time as one would expect. As a matter of fact, our two-year experience with this unit, as used on a common lead antimony battery, has proven its float scheme highly effective. the battery tender i have will charge a battery........ i guess there are just maintainers out there...that will not charge. Battery Tender Plus by Deltran The Battery Tender Plus, like the others in this comparison, is claimed to be a three–stage charger/maintainer. One thing I think I did learn today is that a good full sleave electric jacket/linner is probably way too much for this bikes alternator. I use the "tender" from batteryminder, it stops charging and waits until it needs to charge again based on the battery voltage as it drops over time. Should the units be required to supply more than a designed maximum current while in float (like if the ignition key is turned on), they all trigger into a new charge cycle. First, it must be able to charge a battery until the majority of the sulfate is back in solution, and this requires attaining a voltage of around 14.2 volts; slightly higher is preferable. As a fifth and final stage, this unit claims to shut down, then re-start the charging process every 28 days. Assuming the answer is affirmative, the charger then applies a 1.5 amp pulsing current to bring the battery to near gassing voltage. However, even the smaller Yuasa 900 required only about 30 minutes more than the other chargers (except the Battery Tender) to return the battery to gassing voltage. I have a 2-10-50 charger for heavy duty use, but for just keeping a good battery healthy and ready, the Battery Tender brand is good, and I just buy the "Jr." version which does everything you will need for a low price. I have a charger that does all this as needed. 99 $. During this last “float” mode, it’s desirable to incorporate a method of discouraging sulfation. By the way, I suspect my cheap chargers from Harbor Frieght were the type discussed for just maintaning a fully charged battery. Did it take 30% charge in a few hours on a 2 amp charger? I have a nice Sears charger that allows you to select the charge rate and type of battery and does shut off when it reaches a full charge, but I found out the hard way it is too over high tech for my Deka battery. 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. Funny she says that about me too. 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. As with the AccuMate, placing a load on the battery activated the charge cycle once again. 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. $. This is important, because a charger that tapers the current too early in the charge cycle will take longer to accomplish a full charge, if it ever does accomplish a full charge. 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". This sucked 0.67 amp-hours from the battery prior to testing each maintainer. AccuMate Power-Charge System First up was the AccuMate. Starting with 1976 models, all new street bikes had their headlight switches eliminated, leaving only the high beam selector for controlling the always-on headlamp. It's easy! Thanks for all the help guys. New or different technology has resulted in many competing products, and the four others examined here exhibit charge and maintenance qualities that we prefer over those we noted in the three Battery Tender Plus examples that we tested. We rode for about 15 - 20 mins then parked the bike for a few days. I'm convinced that the Yuasa is the best of them and that the Battery Tender is the worst. October 18, 2011 in Watering Hole. But I think I should get a dedicated car battery charger/maintainer. Had products with similar operating characteristics varied wildly in the time they required to return the battery to 14.4 volts, we’d have suspected our own inaccuracy. Anyone own either of … It’s simply the result of the chosen method of rectification and filtering. This on again, off again float cycle repeated each time the battery dropped to 13.24 volts. It then went into float mode at 12.90 volts. Versatile and powerful, this battery charger is equipped with a simplified 4-Step Automatic charge process used with lead acid and lithium batteries. As the battery’s voltage decays to the unit’s float set point, a small, continuous current is then delivered to hold the battery at that voltage. When I told this to the shop owner where we were today, he smiled and said that bikes alternator has no where near the out put needed to run that jacket and the bike. What is everyone elses opinion on this matter. Yuasa 1.5 Amp Automatic The larger of the two Yuasa maintainers is unique within this group. Most chargers will have several selectable features which you have to decide if they meet your needs. We will see how it does. I put it on a 2 amp charger with a shut off. Battery Maintainer vs Battery Charger vs Battery Tender. The product comes complete with a pigtail lead for permanent attachment to the battery as well as a set of alligator clips for on-the-bench work. We'd leave a note on a friends bike with a place and time on it. These included the Battery Tender Plus by Deltran, the AccuMate sold by Westco, the new Schumacher 1.5 amp Battery Companion, Yuasa’s 1.5 amp unit, and Yuasa’s 900 milliamp product. I checked the bike and it was putting out 13.68 or something volts. $. I had the battery on the charge over night and it was not dead to start with but it was only up to 70%. They do not have the intelligence to properly "maintain" a battery. Battery Tender 12v 1.25 Amp 4 Bank Battery Charger and Maintainer. I'm going to let or it will site for a couple of days while I'm out of town. They will put a charge in but I do think it would take days. 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. Applying a 4-amp load to the battery caused the charger to immediately go back into charge mode. If the Deka gets waaay too low, the charger eventually gives up and says the battery is no good when it is fine. I'll bring it in again and have it load tested and see what happens. The Companion held near its maximum output current until the battery reached 14.3 volts. But wait,,,,,,, we still do the same thing only use the Internet to let everybody know where to be. Most motorists who purchase a battery charger do so for one main reason, to recharge a dead battery. The Yuasa 1.5, the AccuMate, and the Schumacher all performed very well in these tests. But with standard charger the 2 amp setting should show the battery getting at least 14.2 - 14.5 volts during the process. I think I have seen my venture with a low battery many many times and after running the bike for a while, the battery takes enough charge to start the bike. I put the battery on the bigger 55-10-2 amp charger and within a few hours it said fully charged.

Float voltage was 13.23 at 20 milliamps, and the float current contained no pulsation. A battery charger is capable of higher current outputs. You might have to do this a few times, but unless the battery is actually damaged, has shorted cells, or simply old and worn out, this might get you going again. Check it Out 2. A permanent-mount pigtail and alligator clips are both included. We first noticed it at an automotive product show in Las Vegas and were sent a sample for testing. SUNER Power 12V Battery Charger and Maintainer #6. Further, we firmly believe that any temperature compensation scheme should be based ideally on the electrolyte temperature inside the battery. Many riders simply ignore the issue and buy a new battery in the spring. Below that point you are operating off the battery. Ambient temperature during the testing was held fairly close to 70 degrees Fahrenheit. This repeating cycle varies from the float method employed by the other tested units, but should be effective nonetheless. It required a bit more time than its big brother, the Schumacher, and the AccuMate to replenish the charge we’d sucked from the battery. The shop owner said (do I believe him?) Suggested price for the Yuasa 900 is $41.95. Also it will handle Glass Matt Batteries. That said, I ride almost daily with a modified charging system that puts out no less than 14.3 volts at running speed.

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. We would show up and have a bonfire, drink some beers and BS all night about bikes. 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. During float, the Yuasa 1.5 maintained a 10-milliamp current and kept the battery at 13.29 volts. Call 1.877.775.4381. It was a cheap trickle charger from Harbor Frieght. When it gets battery to where it should be it stops til battery needs to be brought back up to full charge. I have yet to have a battery go bad within 5-6 years. These result from electromagnetic interference due to the 60Hz, 120VAC electricity coursing through the building’s wiring.

Automobiles are driven daily, so their batteries don’t get much chance to self-discharge. 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. GolfVenture, Suspecting a defective unit, we obtained two others and tested them in the same manner. The current tapered at 14.3 volts, and this was accomplished by reducing the pulse heights while retaining their shapes. $. But if you’ve accidentally left your key on, don’t plan to go anywhere for a while if you want to completely recharge your battery. They were observed to perform extremely close to their manufacturer’s specifications. The instructions indicate only that the amber charge light remains on until the battery reaches about 14.4 volts and the charge current has decreased to 0.5 amps. Price $88.20. She would be so happy if only her legs were a few (well maybe 6) inches longer. He said the maintanece free batteries can fully discharge and then will take up to 48 hours or more of trickle charging to get them back up to full charge. 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. A second unit allowed the battery voltage to drift between 12.75 and 12.95 volts. 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. It then cut back its output and gradually brought the battery back up to float voltage. You’ll note pulsation in the current waveforms displayed in this article. In this section, we’ll provide you reviews of the ten deep cycle battery chargers we see as the best on the market. 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). The GL1800’s alternator has the capacity to keep its battery from discharging at all engine speeds. Your bike's charging system should keep your battery charged. Voltage was monitored across the battery terminals on a voltmeter with ten megohms input impedance; again, negligible effect on the circuit was the goal. 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. That being the case, the bulk charge mode should hold a current at or close to the unit’s maximum output until the battery voltage is at or near gassing voltage. 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. Item# 167964 ...

It started right up. I think we are headed for the new Suzukie 1300 with the batwing fairing and sound system. The unit then kicked back in with a 0.665 amp current containing 2.25 amp spikes, and it applied this charge until the battery reached 13.56 volts. If it isn't doing so something is wrong with it. 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. I've been running the DEKA ETX18L for going on 5 years. Above that amount, the unit begins actual charging again. Then again, as we stated earlier, the pulsing was not designed for any particular purpose. Should the battery begin drawing more than 200 milliamps at any time afterward, the maintainer will re-start its main charging program.
