The ENERpower BT-C700 is an intelligent table-charger for four AA or AAA NIMH / NiCd rechargeable batteries, with LCD-Display and various functions.This charger has 4 independent charging slots, which allow it to charge simultaneously different batteries of different types and capacities. Five different operation modes are available: charge, discharge, refresh (optimizing old batteries), test (measures the actual capacity of the battery and neutralizes memory effect), Quick Test (measures the internal resistance of the battery). A backlit LCD display provides information with a key press: charging current, battery voltage, charged/discharged capacity, internal resistance and elapsed time of the charging/discharging process. The charging current can be selected from 200mA and up to 700mA for all four slots. The standard is 400mA.Charging current of 1000mA is available for slots 1 and 4, when there are no batteries in slots 2 and 3.Discharging current of 100, 200, 300, 400 and 500mA. Standard current is 300mA The following NiMH and NiCD battery-types can be charged: AA (LR6 Mignon) AAA (LR3 Micro) batteries, NiMH-, NiCd. Highlights    Charging and discharging NiCd, NiMH Lithium Ion-Batteries    Optimization and measuring the maximal capacity of the batteries.    Each charging slot has its own display to inform about charging current, battery voltage and capacity, internal resistance and elapsed time.    With 4 intelligent independent charging slots    Charging current of 200mA - 700mA for all four slots; 1000mA is available for slots 1 and 4 (when there are no batteries in slots 2 and 3)    Discharging current of 100, 200, 300, 400 and 500mA.

The Tensai TI-400L charger has 4 independent charging channels for R6 AA or R03 AAA batteries. Thanks to the backlit LCD display, the device clearly and easily displays the current charge level (25/50/75/100%) on the bar chart. The advantage of the device is also that the batteries are charged separately. The charger has protection against short circuits, incorrect insertion of batteries and overheating. Highlights  Worldwide voltage range: AC 100-240V, 50 / 60Hz Possibility of power supply from a 12V car (cable included) Charging current: DC 1.5V R6 / AA 0.5A / R03 / AAA 0.25A Charging time control based on: - delta V Dimensions: 105 x 65 x 25 mm Weight: 92 g
