Compatible with: Ni-MH and Ni-CD: AA and AAA

The Tenergy TN438 is another top rated charger that is widely and globally used. This is a monster charger with 16 bays that can all be used simultaneously, saving a lot of time and energy.

The TN438 arrived packed with sixteen Tenergy AA premium rechargeable batteries (which we purchased separately at an additional cost). These batteries have a high capacity and are reputedly very long lasting.

Tenergy batteries are ideal for those devices that are frequently used and are especially suited to clocks, wireless mouses, and game boxes.

The TN438 is compatible with Ni-MH and Ni-CD AA and AAA batteries and features a prominent LCD display that displays the charge status of the various batteries.


Another excellent feature of this charger is that it is equipped with smart battery charging technology. This smart charging technology prevents overcharging, automatically discontinuing charge to the battery that is fully charged. It also provides protection against overheating and reverse polarity.

The TN438 also has an adapter that enables it to be used universally, as well as a car adapter. You can use it while on the go, and there is an easy to use refresh cycle that charges and discharges the battery, increasing its lifespan and performance.
