My battery charger helps me alot in saving my battery expenses

I used to buy triple A batteries and double A batteries for my transistor radio and for my daughters toys. It is very expensive and costly because every time the battery gets weak, I go again to the sore to buy again another set of batteries. The expenses for the battery supplies gets bigger and bigger because I always buy frequently. So I have decided to buy some battery chargers and rechargeable batteries. It gives me more savings because I don't have to buy a new set of batteries when my battery gets weak.
