Use Your Homemade Battery Pack To Charge Flashlight Batteries

Easy to use

Battery pack and charger

One of the many uses of the battery pack that I wrote about previously is to charge smaller batteries.  I found a 12-volt battery charger in a garage sale that charges AAA, AA, C, D and 9-volt rechargeable batteries.  It uses a cigarette light style plug which plugs directly into the battery pack.

With 14 amp hours of power, you could charge large numbers of the smaller batteries.  I like the Eneloop batteries made by Sanyo.  They can be recharged between 1000 to 1500 times and will hold a charge for several years.  See a previous blog on Eneloop batteries

A quick search of the internet showed several battery chargers that would work with this battery pack.
