PV Gap

Allen Said:

Does/Can a solar cell battery charger extend the life of a car battery?

We Answered:

It could. Lithium batteries (like in cell phones and laptops) like to be fully dis-charged before re-charging. Lead acid batteries (car batteries) can go completely dead if fully discharged - so, theoretically it could stop that from happening.

Charlene Said:

Does anyone have experience with solar chargers for Ipods, cell phones, etc. I have checked and the prices ...?

We Answered:

I tried it, it's not really worth it. Depending on the charger, you need at least 8-15 hours of uninterrupted sunlight for a full charge on an ipod (varies depending on the device, and the intensity of the sunlight).

Being indoors, interrupting the sunlight, a cloudy day, many things will make the charger less and less useful. Unless you are going on a long trip and not going to be near a power outlet for days at a time, it's barely useful at all.
