Can your battery chargers, charge a dead battery from 0 volts?, also what is the maximum CCA it can handle to?, e.g 550



Hi there, our battery experts have replied with the below.
The Smart Charge charger will not turn on to charge a battery below 5Volts. It needs at least 5-6 Volts to trigger it to start.
The charger can charge pretty large batteries. Keeping in mind the larger the battery the longer it will take to charge as this is only a 4amp charger. It can charge 700CCA - 850 CCA with no issues ,however, will take a lot of time to bring it back to 100% SOC if the battery is very low in charge.
One more point to remember - it is meant to be a maintenance charger and not to charge airport flat batteries.
