You can buy AAA rechargeable batteries, which will ensure you the same quality as a normal battery. AAA or AA staycharged batteries are a great deal.

Let us assume that a normal battery available in the market costs $1. While staycharged batteries costs about $4. You might be thinking that it is cheaper to buy a normal battery. But this is not true; just think if you change your battery once a week, you will find yourself buying 4 batteries a month. That means you are spending $4 a month, which means $48 a year. Using a rechargeable battery you can just spend that $4 only once, and they will last you more than a year
