Review on ⚡ Beleeb Battery Charger 12V 24V Smart Pulse Maintainer 12V/20A(max) 24V/10A(max) Repair Charger with LCD Display – AGM SLA Car Golf Cart Mower RV ATV, Portable Auto-Volt Detection 2Ah-200Ah by Cory Spence

These are used to output 20A at 13.5-14V (I've had the exact same make and model in the past - thought I broke it so ordered it as a spare) , but now this new one only puts out 15 amps MAX. Luckily for me, my old one turned out to not actually be broken and was still putting out 20 amps, so I think this new one will only be a 15 amp backup. Btw, on my old unit I accidentally connected the wires to the battery the wrong way round and was about to plug it in when I heard the reverse polarity alarm go off and then for 2 seconds (before I could get it to the battery). open the cable) the capacitor exploded (loud bang and lots of smoke). I disassembled it and removed the parts of the capacitor that were dangling inside. Haven't tried charging it until now (just think it would be broken) but it still works fine in the end. Find out.
