The list author says: "There are many different AA battery chargers with different features and functionality and different prices. Here's an attempt to identify the chargers that will do the best at charging AA batteries."
"For the hobbyist the best AA battery charger is the Maha MH-C9000 AA/AAA battery charger analyzer by Powerex. This charger will charge quickly or slowly as you choose and will refresh and rejuvenate batteries that have been under performing."
""Keep it simple stupid" is the mantra to follow when you want something to work and this little USB AA battery charger simply works and is easy to use in home, on the road and anywhere else a USB plug is available which is just about anywhere."
"Many time charging 2 or 4 cells simply isn't enough and this inexpensive 8 cell charger will do the job of charging 8 eneloop batteries in about 4 hours. It can even efficiently charge 4 AA batteries in 2 hours if you only populate two slots in each section."
"La Crosse has long been a name recognized with great battery chargers but for some they've not been a solution because they could only be run from an AC household plug. The BC500 however, is a mobile solution because it is a 12v charger that can be plugged into your auto or 12v battery source."
"A Charger that has stood the test of time and is still producing great results with the least amount of effort. The MAHA MH-C401FS is a simple and easy to use AA battery charger that works at home or on the road."
