The Tamiya 15182 - D.C. N-3U Battery Discharger provides a simple method to discharge AA rechargeable batteries used in Mini 4WD models. It helps maintain battery capacity and reduces the risk of reduced runtime caused by partial-charge memory.

Operation is user friendly: insert the AA cells and the unit carries out the discharge automatically. This makes it handy for hobbyists who turn up to long practice sessions or frequent local events and need consistent battery management.
