Lead-acid batteries that have remained in a discharged state for a long time internally build up lead sulfate which can inhibit normal charging. This charger has an operating mode designed to recondition sulfated batteries.
A cooling fan runs while charging, but turns off when charging is complete. The unit then automatically switches to float mode to maintain the battery at full charge. This is very important not only for convenience, but also to prolong battery life. Since the fan turns off after topping off the battery, it works well for building up relatively inexpensive, large capacity, indoor UPSs built around deep cycle batteries (make sure that the battery area is well ventilated and place the battery on an acid resistant drip pan to prevent damaging the floor).
The lightweight, compact, microprocessor controlled charger features a backlit, scrolling LCD display that provides charge rates, status messages and battery diagnostic information. The device is built well, especially considering its low price. The battery clamps have copper contacts and the cabling is heavy gauge. All cables can be stowed inside the charger.
From my experience with the Power On Board 25 Amp Fully Automatic Battery Charger, the device is an outstanding bargain.
EDIT April 4, 2011: The charger has more than doubled in price since the time I wrote this review, so keep that in mind when considering it since there are other good chargers in this much higher price range.
Lead sulfate forms on the battery plates if the battery is discharged for some time which makes the battery difficult to recharge. Reconditioning dissolves the sulfate.
It first gave "Internal Shorted Cell Battery" warning which recommends evaluation by a battery repair store. I ignored the message and gave the battery a 20 minute charge as part of the reconditioning procedure then tried the recondition feature again. The reconditioning process took over and twenty four hours later, the battery was fully charged.
Tips: Almost all lead acid batteries evaporate water from the cells, even the low or free maintenance batteries. Mine was low maintenance so I cleaned the top of the battery and the posts, took a flat head screwdriver and popped the two caps off to reveal the reservoirs. I filled them up with distilled water then slapped the caps back on. Unless you know what you are doing, let someone knowledgeable do it because of the battery acid danger.
Other comments not mentioned in product description up above: the instructions weren't very clear because of all the warnings and cautionary statements about safety; the first two pages were warnings. I sat down and took a highlighter to note the necessary instructions. I never tried the 75 amp jump start feature or the alternator diagnostic feature. The battery cables and clamps store neatly in the unit compartment. The fan is a bit noisy but tolerable and who cares if it's in your garage.Read more ›
AS a regular charger, I used it on a dead car battery and it started charging right away. First used the 75 amp starter thing, twice and it started. But, as I know from solar batteries, when they are really low/dead you want to slowly bring them up and then at about 20% hit them hard and fast. So, I'll check the dead battery in about 15 minutes (the time it took me to write this) and will turn it to 25 amp and I'll have a fresh battery no doubt. I highly recommend this charger. Unfortunately it isn't offered many places anymore. It has been rebranded, repackaged and reduced in quality. So, good luck and happy charging.
I'll keep this one at home and get a 40 amp for the solar system. Needs more juice for 6 x 6volt batteries.
