Smart Charging

With smart charging capability, the TN156 automatically identifies when batteries are full, so it will stop charging at it's full capacity to reduce wear & tear on your batteries and to extend battery life.

Independent Charging Channels

Charge any combination of 1 to 4 rechargeable AA and/or AAA batteries at a time. No need to charge only in pairs like other basic chargers on the market. Simply flip down the channel latch for AAA batteries and the TN156 automatically recognizes AAA batteries to charge at the appropriate charge levels.

Fast Charge Rates

The TN156 is designed to offer a fast charge rate without comprising battery life. It efficiently charges at a rate that best maximizes quick charge time, and reduces heavy load & wear on your batteries.

LCD Display allows easy and proper charging indication of your battery. Easily see when batteries are charging, full, or if there is a bad battery
