The chargers featured below are some of the “smartest” out there — they have built-in protection to prevent overcharging or undercharging. They also perform battery testing and recovery.
PowerEx MH-C808M “Ultimate Professional” Charger
The MH-C808M charger by Maha can charge any combination of 1 to 8 batteries. You can mix and charge AA, AAA, C and D sized cells at the same time on individual charging circuits. Each battery size also has its own fixed contact charging points (i.e. not a spring). An LCD display shows charging and conditioning status of each rechargeable battery.
Maha’s chargers can restore batteries to their optimal performance level by repeatedly charging and discharging them. It also has intelligent charging technology and overcharge protection. It comes with an international AC adapter, and short-circuit protection.
The PowerEx MH-C808M is available from Amazon for around $90.
PowerEx MH-C9000 WizardOne Charger
The PowerEx MH-C9000 charger is now our pick for an inexpensive battery charger. This charger has four independent slots for AA or AAA NiMH or NiCd batteries. It can provide charging current from 200 to 1000mA for 4 cells, or up to 1800mA for two cells. Just like the Maha Ultimate Professional charger, each battery is independently charged. It also features battery analysis and refresh functions.
Under testing, this charger has proven itself to be superior to the LaCrosse charger (our previous recommendation) — see the Amazon reviews for the MH-C9000 for more information.
The PowerEx MH-C9000 is available at Amazon for about $50
LaCrosse Technology BC-1000 Alpha Battery Charger The LaCrosse Alpha BC-1000 Charger has sophisticated monitoring circuitry that controls the charging process, and it is also capable of “reconditioning” batteries by running a series of discharge-recharge cycles. The charger shows battery voltage and charge status on its digital display. It has four separate charge channels so you can charge one, two three or four batteries at a time – even on individual charge programs. This allows you to test one battery while charging the others. It comes with four AA and four AAA batteries, four battery adapters (which convert AA sized battery to C and D sizes) and a carry case. Note, however, if you want to charge C or D size batteries, you’ll want to get the Ansmann chargers below. Available from Amazon:
