Frequently asked questions
How long does it take to recharge a car battery?
It depends on its capacity and condition. For example, a 70 Ah battery that is half empty will recharge in a few hours at 10 A; the automatic mode adjusts the current by itself.
Can the charger be left plugged in all winter?
Yes, the 8-step charging includes maintenance charging that prevents overcharging.
Is this charger suitable for LiFePO4 lithium batteries?
Yes, a dedicated LiFePO4 mode is included.
Does the booster function replace a portable jump starter?
It helps start the vehicle when the charger is plugged into the mains. For roadside assistance, a standalone booster remains necessary.
Recharge, maintain, and protect your batteries all year round with a single device.
