Remove batteries after the charger indicates full charge or when charging is complete to avoid prolonged trickle charging beyond recommended periods.

Recommendations

Use the charger with Nickel‑Metal Hydride (NiMH) rechargeable batteries only. Do not attempt to charge alkaline or non-rechargeable cells. For best battery life, store batteries partially charged if not used for long periods and avoid exposing the charger to extreme temperatures. If a battery is detected as faulty or non-rechargeable, remove it immediately and do not attempt to use it further.
