Compatible Olympus cameras

This lithium-ion battery replaces the BLS-1 and PS-BLS1 packs used in Olympus E-400, E-410, E-420, E-450, E-620, EP-1 and E-P2 models. It delivers 7.4 volts and 1150 milliampere-hours in a black casing measuring 55.06 by 35.39 by 12.76 millimetres. The cell is brand new and built to match original specifications. Photographers using other Olympus bodies or different battery part numbers cannot use this pack.

Li-ion voltage and capacity limits

The 7.4 volt nominal output is fixed by the two-cell lithium-ion chemistry and cannot be adjusted for cameras expecting a different voltage. Capacity of 1.15 ampere-hours determines how many shots or minutes of video are possible before recharging; it will not exceed the original BLS-1 rating. The physical footprint of 55.06 by 35.39 by 12.76 millimetres defines the maximum size the battery compartment can accept.

Check your camera model and battery code

Verify that your Olympus camera appears in the supported list: E-400, E-410, E-420, E-450, E-620, EP-1 or E-P2. Confirm the original battery part number printed on the old pack reads BLS-1 or PS-BLS1. Ensure the battery compartment can accommodate the stated dimensions and that the charger you own supports lithium-ion cells of this voltage.
