GP Batteries GP10AAAHC-B4A NiMH 1/3 AAA 170 mAh Rechargeable Battery (1-Pack)

For compact cordless phones, medical devices, and small electronics, the GP10AAAHC-B4A delivers dependable NiMH power in a 1/3 AAA size that standard AAA cells simply cannot fit. Unlike disposable batteries that end up in landfill after a single use, this rechargeable cell offers up to 500 charge cycles, cutting waste and long-term cost. Its flat top terminal and 170 mAh capacity are tuned for low-drain devices where space is at a premium.

Highlights

• NiMH chemistry with 1.2 V nominal voltage and 170 mAh capacity
• Compact 1/3 AAA cylindrical form factor fits tight battery compartments
• Rechargeable up to 500 cycles for economical, eco-friendly operation
• Flat top terminal ensures reliable contact in custom battery packs
• Wide discharge temperature range from -20°C to 50°C
• RoHS compliant and packaged in a single blister for retail

In daily use

Installed in a cordless phone handset or a small medical monitor, this cell provides steady voltage until the device signals a low battery. Recharging is straightforward with any compatible NiMH charger; the cell accepts standard charge rates and tolerates occasional partial charges without significant memory effect. Its low self-discharge is typical for standard NiMH, so it is best suited to devices used regularly rather than stored for months. The flat top design requires a holder or tab connection, making it ideal for OEM replacements and hobbyist projects alike.
