Modern electronics are getting ever more powerful and coming with ever more capabilities, but no matter how great your electronic device is, it's powerless when it runs out of batteries. With that in mind, finding batteries that will keep your gadgets going is of the utmost importance.

Rechargeable batteries have come a long way and are capable of keeping their charge longer and carry more charge cycles than ever before. Having rechargeables will save you in the long run from constantly buying and disposing of batteries.

What Are Rechargeable Batteries?

A rechargeable battery is a type of electrical battery that can be used over multiple charge cycles. While rechargeables typically have a higher initial cost compared to disposable batteries, their ability to be reused over a long period of time typically means that they cost less in the long-run and also have a smaller environmental impact. When it comes to purchasing rechargeable batteries, the key factors to look for are charging time, shelf life and the number of charge cycles they have.
