3.6 V NIMH Battery Packs

A 3.6 V NiMH battery pack provides a compact, rechargeable source that fits directly into many hobby‑level robotic and sensor modules. The standard JR‑style connector and 4 inch lead make wiring straightforward, allowing quick replacement or integration into existing chassis. Packs built from three 2/3‑size AAA cells suit low‑power drives and handheld devices, while three full‑size AA cells deliver higher capacity for longer runtimes. Capacity ranges from a few hundred to over two thousand mAh, giving flexibility between lightweight, short‑duration tasks and extended operation where space permits. The nominal 3.6 V output matches common motor drivers and microcontroller boards, and the sealed NiMH chemistry offers reliable performance through many charge cycles without the memory effect concerns of older chemistries.
