If you are looking to charging your car battery with a charger, look no more, as the Optima Digital 400 12V Performance Maintainer and Battery Charger comes with great features to guarantee a healthier battery.

It features a hybrid LED battery-charging gauge with an LCD screen and a quick-set battery type selection for easy operation.

You can hook this battery charger to the bonnet of your car and leave it to do its work. It has a 4amp max which can guarantee fast charging and a microprocessor that controls the charging to make sure that it floats once the battery is full.

The Optima 400 also has advanced safety features including no spark, reverse polarity, diagnosis of battery errors, and microprocessors to prevent overcharging. This battery is great because it revitalizes deeply discharged batteries as low as 1.25A where others cannot. This car battery charger starter would be a great addition to your car.


  • This auto battery charger can rekindle a deeply discharged battery and can extend the battery’s life span
  • It is very portable and has a USB port for charging your phone too.
  • It has a 12amp max which can comfortably fast charge your battery if you are late to work


  • High amp-hours usually result in battery damages in the long run; using the 12amp max option might get you on your way faster but might deplete the life span of your car battery.
