Caution

This charger is optimally designed for protected cells although will work with unprotected cells. Tolerance of this charger may allow charge of unprotected cells up to 4.3 volts, this is still safe for unprotected cells although is not optimal for cells durability of recharge cycles. Due to the high current of this unit, do not use it with spacers to charge smaller cells such as the CR123.
