The Ni-Cd N3-U Battery (Japanese: カドニカ単３型バッテリー, Kadonika Tan 3-gata Batterī) was a battery manufactured by Sanyo (A subsidary company of Panasonic) and released by Tamiya in the 80's. It was the company's first AA-size rechargeable battery.
This battery was meant to power Tamiya's Quick Drive R/C cars. It comes in 2-battery packs and 8-battery packs and is included with certain Tamiya battery chargers.
The external of the battery was mostly in gray with N3-U and Tamiya labels on it. later revision of the same battery has the green recycle label on the lower part of the battery.
Compared to the Mini 4WD Ni-Cd Battery, the regular Ni-Cd battery from Tamiya has lower electric output.
However, as with other nickel-cadmium batteries, it suffers from a high self-discharge rate and contains cadmium, the use of which has declined in recent years due to its toxicity. This, along with the memory effect common with other nickel-cadmium batteries, led to it being discontinued and replaced by nickel–metal hydride batteries like the NeoChamp.
