Replacement Battery for HME Base Stations
This 2000mAh nickel-zinc pack replaces the original power source in HME MB100, MB300ES and Pro 850 intercoms as well as WS200 speaker stations. It matches the 7.20 V specification and the 90.70 x 59.20 x 16.10 mm form factor so the battery slides into the existing compartment without modification. A built-in protection circuit guards against over-charge, over-discharge and short circuits. The pack is certified to ISO 9001, RoHS and CE standards.
Upgrading from a Worn Original Cell
When the factory-fitted battery no longer holds a full shift charge, this unit restores the rated 14.40 Wh capacity and 11.1 V nominal output. The jump is worth it if run-time has dropped below operational requirements or if the original pack shows swelling or connector corrosion. Installation follows the same connector orientation as the OEM part; the fully decoded chip reports status to the host exactly like the original. No firmware update or calibration tool is required beyond two to three full charge cycles.
Limits of Nickel-Zinc Chemistry
Nickel-zinc cells deliver the rated voltage in a smaller footprint than nickel-metal-hydride alternatives, but they self-discharge faster during long storage. The chemistry is rated for operation up to 60 °C (140 °F); sustained exposure above this temperature accelerates capacity loss. The protection circuit disconnects the pack if voltage or current exceeds safe thresholds, which can interrupt a transmission if the load spikes. Users needing multi-day standby without recharging should plan for more frequent top-ups than with lithium-based packs.

Questions about this item
Will the 90.70 x 59.20 x 16.10 mm dimensions fit my HME WS200 base station battery compartment?
The pack measures 90.70 x 59.20 x 16.10 mm and is listed as a direct replacement for the HME WS200, WS200 Speaker and WS200 station, so it matches the original compartment.
How do I install the replacement battery and what step is often missed?
Connect the pack's plug to the device's internal connector, ensuring it seats fully; the most common mistake is leaving the connector partially inserted, which prevents charging.
When will this 2000 mAh nickel-zinc pack need replacing?
After roughly 2 to 3 full charge and discharge cycles the battery reaches peak capacity; replace it when run-time drops noticeably below the original 2000 mAh rating.
