Tamiya 55099 1/32 scale 4WD-compatible Power Champ GZ AA battery 4-pack  [55099]

Tamiya 55099 Power Champ GZ AA four-pack for Mini 4WD use

The Power Champ GZ AA set provides four R6/AA/UM3 alkaline cells packaged for hobby use. These are the same single-use alkaline chemistry previously offered in a twin pack, now supplied as a four-pack for easier replacement and storage.

For experienced Mini 4WD owners and collectors the pack is useful as a consistent, off-the-shelf power source for display models, track practice sessions, and general maintenance. The cells are intended as disposable alkaline batteries; recycling and proper disposal should follow local regulations.

Compatibility is broad: the cells fit standard AA holders used across Mini 4WD bodies and many after-market battery trays. Do not treat these as performance upgrades; they are a convenience supply for keeping models powered during handling, display, or casual running.

Storage advice: keep unopened packs in a cool, dry place and rotate stock to avoid long-term self-discharge. If a model is being stored long term, remove batteries to prevent leakage.
