The best rechargeable batteries: our 2021 buying guide

Rechargeable batteries are still far less common than disposable batteries, despite the advantages they have over the latter. They are indeed more durable, in addition to being more economical overall. Check out our guide to buying the best rechargeable batteries in 2021.


2020 was the year of containment. So much so that the use of batteries in homes has literally exploded. Cloistered at home, the French used far more battery-powered objects than usual. As LSA reports, 483 million units were sold in this way last year, an increase of 13%. And consumers are increasingly opting for rechargeable batteries, albeit more expensive.

That being said, the price gap catches up very easily thanks to their lifespan. Rechargeable batteries thus have a minimum of 400 recharge cycles, with an average of 1000 cycles. As for their ecological advantages, they considerably reduce the extent of recycling. But also pollution, knowing that a single pile can infect up to 1 m³ of soil and 1000 m³ of water.

To supply them with energy, you obviously need a charger. There are different ranges, with prices ranging from around fifteen euros to over 200 euros for top quality models. These offer advanced features such as fast charging or 100% charging stop.
