Trickle charger pack

A trickle charger pack is not going to jumpstart a car battery. But it will ensure that your car battery lasts longer, and it can help prevent the need to have to jumpstart your car battery in the future.

Trickle chargers help batteries maintain their full capacity -- they charge a battery at the same rate it is discharging. Car batteries, even when the car is not running, can lose their charge (especially if parked for longer than a couple of weeks).

Trickle chargers sold here at SolarHome.org are of course, solar powered. You can find them with flat fixed panels and folding modular panels. For use with batteries, the panels work in direct sunlight as well as through clear glass.
