Product Description 1.2 V AA Ni-MH Rechargeable Batteries, 12-pack Overview: We chose Tenergy Premium 2500 mAh Ni-MH batteries as an environmentally and economically friendly option to power our ActivityBot 360° and cyber:bot robots. Used extensively during development of the ActivityBot robot’s Feedback 360° servo, these batteries delivered a more consistent performance, and lasted almost as long on a single charge cycle, as alkaline AA batteries. Features: 12-pack of AA, 1.2 V, 2500 mAh batteries Rechargeable Nickel Metal Hydride formula Compatible with the Tenergy 12 AA / AAA Fast Battery Charger (#752-00021) Not subject to Lithium ion battery shipping restrictions Parallax Small Robot Compatibility: ActivityBot 360° (#32600) – highly recommended cyber:bot robot kit (#32700) – highly recommended SumoBot WX Competition Kit (#32134) – highly recommended ActivityBot (#32500) – acceptable; but re-calibrate if using 1.5 AA batteries previously Boe-Bot Robot (Serial, #28132 or USB, #28832) – Four 1.2 V cells are not adequate, but may be used after switching to a Battery Holder 5-AA Barrel Jack (#753-00007) Note: The original BASIC Stamp SumoBot (#27402) requires 5 V. Four of these 1.2 cells are not adequate for reliable operation. Our 5-AA battery holder may be mounted under the chassis, but customer modification would be required to remove the barrel plug and strip/tin the leads. Note: The Shield-Bot with Arduino Uno (#32335) requires 7.5 VDC. Five of these1.2 V cells are not adequate for reliable operation AA Ni-MH Rechargeable Battery Specifications, Per Cell: Type: AA cell Chemistry: Nickel Metal Hydride Nominal capacity: 2500 mAh Nominal voltage: 1.2 V Weight: 29 grams Dimensions: 14.5 mm diameter x 50.5 mm length
