We briefly reviewed battery chargers in a previous post “The Best Rechargeable AA Batteries“. But let’s take a look at the best “Universal Battery Chargers”. These are chargers that can handle AAA, AA, C, D sized cells, and well as 9V cells.
The Best Overall Charger: The Maha PowerEx “Ultimate Professional” Charger
Maha’s Ultimate Professional Charger almost lives up to its hyperbolic name. This compact charger 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 universal battery 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 also comes with an international AC adaptor, and short-circuit protection.
It is available from Amazon for around $96.
The Most Affordable: The Maximal Power FC999 Universal Rapid Charger
The Maximal Power FC999 Universal Rapid Charger is a versatile and reliable charger. It has a microprocessor to intelligently monitor and control the charging cycle in each charging port for overcharge and short-circuit protections. It is capable of charging a wide range of batteries, namely: AA, AAA, C, D, N, 9V, Ni-MH (Nickel Metal Hydride), Ni-CD (Nickel Cadmium), RAM (Rechargeable Alkaline Manganese) and even Alkaline (previously Non-Rechargeable).
It’s available on Amazon for about $28.35
