Review on 🔋 Intelligent Pulse Repair Maintainer Car Battery Charger - 12V/24V, 1-15 Amp, 250W Trickle Charger with LED Bar Screen, Ideal for Car, Boat, Marine by Roel Lebron

First of all, this is an attempt to charge my 12 volt battery, which may damage the battery and the inverter connected to it. I found and stopped it at 15.5V before anything serious could happen, like a battery burnout or a fire. I think it may have started charging it to 24V automatically. Obviously this is a serious safety issue. This charger never sent more than 7 amps out of the 15 amps to my 12v 100ah battery (was 11.9v so completely drained). It also appears to turn off (the charge indicator goes off) once it reaches a full charge. So don't expect it to reliably keep your battery charged when you've got a load connected. it won't work for campers and the like. I wasn't expecting much but wow it's rubbish.
