• [WARNING!!!] : For batteries with a capacity of 20Ah or lower, we recommend not using the "auto shut-off" feature on this charger. Instead, turn it off manually to stop charging. When charging older batteries, it's important to monitor the process early on. If you notice abnormal readings from the charger or if the battery becomes excessively hot, stop charging immediately. Feel free to contact us anytime—we’re here to help with any issues you may encounter.

• [Percentage Display + Automatic Shut-off ] : The digital LED screen with charging percentage is easy to read, allowing you to monitor the battery’s charging status at a glance. In auto shut-off mode, the 12V/24V car battery charger automatically stops charging when the battery is full to prevent overcharging. The maintenance mode uses pulse current to restore and extend the life of old, depleted, stratified, or sulfated batteries after they’re fully charged.
