I wanted to ensure that my charger would work with the batteries I use in my vehicles.

Portability and Design

I appreciated the portability of some trickle chargers. A compact and lightweight design allows me to easily store the charger and take it with me when needed. I also looked for chargers with built-in mounting options, as this made it easier for me to secure the charger in my garage or vehicle.

Price Range and Warranty
