Replacement battery for Olympus recorders

This nickel-metal hydride cell delivers 2.4 volts and 800 milliampere-hours of capacity. It matches the original dimensions of 46.1 by 21.0 by 11.0 millimetres and weighs 50.0 grams. The pack is certified to ISO9001, RoHS, CE, UN38.3 and MSDS standards. Built-in protection guards against overcharge, over-discharge, over-voltage and short circuits.

Compatibility and limits

The battery fits Olympus DS-4000, DS-5000ID, DS-2300, DS-5000 and DS-3300 voice recorders and replaces part numbers BR-403 and BR-402. It will not work in devices that require a different voltage, connector layout or chemistry. Buyers who need a lithium-ion pack or a higher capacity cell should look at other options.

Deciding specification

The critical figure is the 2.4 volt nominal voltage combined with the 800 milliampere-hour rating. If your recorder specifies exactly these values and uses the BR-403 or BR-402 form factor, this cell is the correct replacement.

Questions about this item

How often will the Ni-MH 800mAh pack need replacement?

The battery pack carries a 1 Year specification; typical Ni-MH cells last several hundred charge cycles before capacity drops noticeably.

What limits runtime during continuous use?

Capacity is 800mAh at 2.4V, giving 1.92Wh total energy; sustained current draw will determine how long that lasts.

Does the pack get hot or draw extra power when left on all day?

Ni-MH chemistry self-discharges slowly and has no active cooling; heat only appears during charging or high-load discharge.
