The GP220AAH/T is a rechargeable Nickel Metal Hydride battery and is AA in size. Please note that these are industrial flat top cells and are designed to be used primarily in battery packs.
These batteries are made to the highest quality standards and have the additional benefit of being qualified to the UL standard for product safety. This makes them the ideal choice when working with battery packs.
It is not recommended to solder directly to the battery, hence the addition of flexible solder tabs is required.
The cells are nominally 1.2V, have a typical capacity of 2200mAh, with a minimum capacity of 2250mAh. They can tolerate discharge currents of between 220mA and 6600mA and should give you around 500 charge and discharge cycles.
The GP220AAH/T is a widely used in many applications and we quite often supply them as spare batteries for rechargeable toothbrushes and rechargeable shavers.
