Tenergy 4-Bay NiMH/NiCd/Li-ion Intelligent Charger with Backlit LCD,
TN456
Tenergy's TN456 is an intelligent charger designed for 1.2V NiMH / NiCd (A, AA, AAA, SC,
C) and 3.7V Li-ion (26650, 22650, 26500, 18650, 17670, 18490, 17500, 17335,
16340(123A), 14500, 10440) rechargeable batteries.
TN455 can be used to charge your batteries, as well as to test their capacities. Its backlit
LCD allows you to
see the charging status in real time, including the charging current,
battery voltage, accumulated capacity, internal resistance, and elapsed time.

OPERATING INSTRUCTIONS
1. Intended Use
The product is designed for use with NiMH, NiCd or Li-ion rechargeable batteries.
It provides four independent charging slots compatible with these battery sizes: A, AA,
AAA, A, SC, C, 26650, 22650, 26500, 18650, 17670, 18490, 17500, 17335, 16340
(123A), 14500, and 10440. Each charging slot can
be independently controlled, and
has its own display to show various information, such as charging current, battery
voltage, charged capacity, internal resistance, and elapsed time.
The charging current can be selected from 300 mA, 500 mA, 700 mA and 1000 mA.
Batteries of different types (NiMH/NiCd/Li-ion) and sizes with different capacities can be
charged at the same time. This charger uses the
minus delta voltage (-ΔV) function to
determine the charging status for NiMH/NiCd batteries, and the CC-CV(Constant Current-
Constant Voltage) function to control the charging of Li-ion batteries. The charger also has
