Description
Switch mode lithium ion chargers are designed to effectively charge lithium ion batteries while protecting the batteries from over-charging. All charger ratings are based on a nominal input of 90-264VAC/47-63Hz. The output current ranges from 500mA to 1.3 Amps
Features:
- Medical approved (EN 60601)
- 3 step charge control
- Current detection as charge termination
- Switch mode charger with universal input voltage
- Charges 1 to 7 cell packs
- Protected against reverse polarity and short circuit
- LED status indicator
- Custom specifications on request

Functionality:
Once the charger is attached to a lithium ion battery and then plugged in, the charging process will begin. The charger will subject the lithium ion battery to three steps of charging.
During the first step, the charger enters into 'fast charge' mode. During this step, the charger is in constant current mode with the current rate remaining at its maximum rating.
In step two, the battery will be nominally 80-95% charged, and the charger switches into constant voltage mode (current is no longer being provided at its maximum rate). The charger will continue to provide a constant voltage until the charge current decreases to the charge termination level.
In the third step, the charge process is complete. Charging has ceased as no current flows to the battery.
Note: The Prices include CORDSETS and adapters. Please call / specify the country this will be used in for us to send an appropriate cord. If no country is specified, we assume that it is for North America.
(Please mention the voltage and Amp Hour ( Ah) rating and or the watt hour (Wh) rating of the battery pack the charger will be used for while you place your order)
