Charge Mate 2502

A secondary battery is becoming increasingly common. As a second battery can prevent the main battery from depleting and being unable to start, this seems like a safe and reliable solution.

The second battery, however, also has to be charged regularly. The Charge Mate series connects both batteries during charging and keeps them isolated when discharging.

The Charge Mate 1202 and 2502 are especially practical for small systems.

I brought in my 2008 Toytoa Tundra for a new radio head unit. Sean was extremely professional and helped me pick out a Kenwood unit with built in GPS. He even installed a front and rear camera set up which makes parking my truck so much easier. The best part is how dependable this new head unit is. Several months later, and I have no issues with it. I'll definitely be back in the future for more upgrades.
