FAQ

Common questions

Everything you need to know about smart charging

Is it safe to leave connected overnight?

Yes! Thanks to the intelligent CPU control, the charger automatically stops when the battery is full and enters a maintenance mode. It won't overcharge or damage your battery.

Will this work for my motorcycle and my truck?

Absolutely. Carertery is broadly compatible with both 12V and 24V systems. It works on cars, trucks, motorcycles, boats, and lawnmowers using Lead-Acid, AGM, GEL, or Wet batteries.

Can it really fix a dead battery?

Our Pulse Repair technology uses high and low frequency pulses to break down sulfation on lead plates. While it can't fix a physically broken battery, it can significantly restore capacity to drained or old batteries.

What happens if I connect the clamps to the wrong terminals?

Nothing bad! The charger has integrated reverse polarity protection. It will simply alert you on the LCD screen and won't send power until the clamps are corrected. No sparks, no damage.

Does it need a special power outlet?

It works with standard US 110V-220V AC household outlets. It's designed for easy use in any standard garage or workshop environment.

How does the temperature mode work?

It's automatic! Below 10°C (50°F), it enters Winter Mode to boost charging voltage. Above 28°C (82°F), it enters Summer Mode to prevent the battery from overheating.

Is it loud when charging?

Not at all. It features a built-in cooling fan that is whisper-quiet while ensuring the unit stays at an optimal operating temperature during the charging cycle.
