FOVAL 2000mA Automatic Trickle Battery Charger 12V Fully Automatic Battery Charger for Car Motorcycle Lawn Mower SLA AGM GEL CELL WET Lead Acid Batteries

Forget all the negative reviews. Some of the people who wrote negatively about it, did not know what they are doing.So I left my GSX-R 600 ignition on after a ride...Totally drained the battery. It would not even light up. I asked my cousin for a his battery charger/ tender but it was a pain to remove his tank and all on his Ducati so I bought this after reading the reviews. I saw some negative but I usually avoid those as those are the people who do not know what they are doing. So I got it on Sunday and installed it first removed - first then +. Installed the tender attachment and reinstalled battery + then - back on. Plugged in the quick connect to the unit and lit up and looked at the lights and what they stood for. Said charging. Let it sit for 3 hours. Lights turned on which was excellent. Let it stay over night and then Monday morning, looked at the charging unit and it and light for fully charged was good. Turned ignition on and everything lit up and then started the bike...BOOM!!! Started like a charm. Seems to have started easier than in the past which shows I probably needed a tender even though I ride twice a week but only on weekends. Took me less than 20 minutes to install. Works like a charm and keeps the bike tended. HIGHLY RECOMMEND this Charger/ Tender. For the price it is unbeatable and the quality is solid and not as flimsy as people said it was. So as the title states, beware of negative reviews...If I followed negative reviews, I would have just bought a battery which would never have raised my awareness and need for a Charger/ Tender.

I have a marine deep-cycle lead-acid battery attached to several solar panels. I use this array for some lights, running an audio amp, and for charging NiMH and Li-Ion batteries in my cell phones and Kindles, etc. On days when it is rainy and dark, and especially in winter here in the Pacific Northwest, I need to use an auxiliary charger to keep the lead-acid battery topped off. This little charger does the trick. It is small and can be tucked out of the way, and then switched on (using a separate AC switch) when I need it. It is a smart charger and knows how to go from bulk, to absorption, to trickle properly. I can run it parallel to the charge controller with no problem. I highly recommend it.

I ordered this on an amazon deal because I was looking for a smart automatic maintainance charger. I tested both on a lead acid and AGM style 12 Volt automotive batteries and was pleased with the charger's performance. I keep it in my vehicle for those road trips to friends and family so I can keep my battery topped up and maintained. As its a smart charger I can safely leave it charging overnight. Would recommend this for anyone in the market for a maintainance charger. Please note that this cannot jump start a car.

My battery was dead as a door nail and this unit charged it to full capacity in 2 days. Those expecting a much shorter charging time should not expect this device to do that. IT IS NOT meant for that so this is not a knock. It actually performed better than even the makers described. According to them the battery should still have some charge (around 3V) for this device to be able to work. But again, my battery was completely dead and it still charged it (as another buyer noted) within 48 hours. It does get quite warm but that is no surprise considering I used it to charge a dead battery versus a weak one. For the money, it did a bit more than it was intended so worth it.

I purchased this charger (2 amp) to charge a replacement battery that I installed in a Peg Perego (kids John Deere tractor). I had previously purchased their 800mA model for my kayak and loved it. I needed this one for the kid's toy because it can charge faster and it is safe for them to use. They can easily plug it up and wait for the "charge complete" light to illuminate. If they forget about it, it's no big deal because it won't overcharge the battery. This is a simple charger that is easy to use. I also like the fact that it comes with hooped wiring as well as clipped wiring, although I did not use them for my application.

I use this charger to keep the accessory battery on hybrid auto full when I do not use the car for a few days. Starts at 2 amp level when first connected and cycles back to trickle for maintenance when the battery is full. This is 12 volt only and I used it to replace a unit that was both 6 and 12 volt. Its problem was that it could not sense the proper voltage and so was as likely to be in 6 volt as 12 volt mode (not good). The Foval with 12 volt only does not have that problem and keeps the battery topped off, so far successfully for over 6 months.
