Clore AutomotivePL2310 10-Amp Fully-Automatic Smart Charger, 6V and 12V Battery Charger, Battery Maintainer, and Stable Power Supply with Temperature Compensation

I bought three different chargers before a friend recommended this one and it works great! I love that when it’s connected it tells current percent charge level of your battery which you can see change as it charges the battery. Unlike the others it works as it should.

This is a quality product as a battery charger but I bought it as an unattended maintainer which it does not work for. If the power is lost this unit has no way or ability to restart charging automatically. Bummed about that since it advertises as a Maintainer, and while technically not a lie, its expensive for something that can't be relied on.

I use it to try to restore a group of 6 V deep cycle golf cart batteries and it preformed flawlessly as a charger. It's not a battery reconditioner but with the different amp charging rates, I could slow or speed up the rate of charge. How effective my experiment was has yet to be determined. They were already reconditioned once so I'm not very optimistic. So far, they are charging and discharging at the same rates as before. I'm hoping a few more charge and discharge cycles with an attached pulse desulfanator may start to improve them. I tried to clean the battery plates and chemically desulfanate them first.

Still getting to know the charger. Was giving it a trial run and It turned itself off overnight sometime while charging a one year old standard battery on the 2 amp setting. I think it's supposed to stay on and maintain the battery long term. On a different vehicle, which is outdoors, I couldn't leave it plugged in overnight but I could see that after 8 hours it was in Phase 7 and maintaining the battery. However, the only way to KNOW it was in Phase 7 was to get the manual out and compare the voltage read outs to the graph. The problem being that the indicator lights light up the same for Phase 4, Phase 6 and Phase 7. The manual recommends to leave the charger hooked up until it's in Phase 5 - steady green with no flashing yellow. When the yellow is flashing and the green is steady you can't easily tell which side of Phase 5 the battery is on unless you pull out the graph and compare voltages too.

I bought this for my father as a gift. He is not tech and he is very pleased with it. It does seem to work fairly well. I do think it is pretty high priced for what you are getting here though as I have bought considerably cheaper chargers on Amazon that offered more power and features which work every bit as well or better.
