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 1.0 Amps to 2.3 Amps
Features:
- Medical approved (EN 60601)
- 3 step charge control with timer
- Switch mode charger with universal input voltage
- Protected against reverse polarity and short circuit
- Charges 3-8 cell battery packs
- 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 (timer mode), 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 timer has run out.
In the third step, the charge process has stopped. 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)
