According to metaefficient.com the best rechargeable AA batteries:
- The best energy capacity (2550 mAh) — get the Eneloop Pro
- The maximum recharge capacity (2100 times) — get the 4th Generation Panasonic Eneloops
- To save some money and don’t mind a little less performance from your batteries — get the Imedion by Maha
I’m using Eneloop by Panasonic (code BK-3MCCE) 1.2V 1900mAh. The price is RM41.00 for 2 batteries. You can use it for maximum 1500 times of recharging.
