Duracell Duralock Pre-Charged AAA Batteries use a technology known as slow discharge, which allows them to hold a charge 5 times longer than ordinary HR03 rechargeable batteries when not in use. They can be used anywhere AAA batteries are used, but instead of throwing them away like normal batteries; they can be reused over and over again.
Duracell's rechargeable batteries hold a charge for up to a year and can be charged hundreds of times. Since these batteries are longer lasting, they are perfect for high energy using devices. They even arrive pre-charged out of the pack, so they do not need to be charged before first use.
Rechargeable batteries save money and benefit the environment by creating less waste, and Duracell is one of the best brands to choose when looking for these batteries.
