Yes not enough to turn an engine over, but plenty for an led strip light
12V solar panel battery charging
- Thread starter jj4091
- Start date
My neighbour's 2011 diesel Opel Omega failed to start ~ 2 years ago (original 95 AH battery), the terminal volts were 11.8 so I connected in my 3.8A smart charger, after 32 minutes the battery/charger were up to 14.3V and the charger then went into trickle mode, (battery obviously knackered), 15 minutes after disconnecting the charger the terminal volts were 12.5 and the car started immediately and was constantly charging at 14.3V so alternator OK, next morning same story, no start initially, so new battery. Its amazing that my charger had only put 2AH into this battery in 32 minutes and it was then capable of starting the car even if only once, I can only explain it by the fact that while a cranking current of say 400A is required the energy (AH) required is quite small, a 3 sec crank at 400A only requires 0.33 AH.
