Why does the indicator light on my Mitzu MC-202 battery charger stay on even after 24 hours of charging?

Based on the manual and user feedback for the Mitzu MC-202, here is what you need to know regarding the indicator lights:Continuous Light Behavior: Many basic chargers in this category, including some versions of the MC-202, do not have an automatic shut-off or a light that changes color when charging is complete. One user review specifically notes that "there is no indicator to tell you if the batteries are already fully charged."Charging Time: The MC-202 has an output of 120mA for AA batteries. If you are charging the 1300 mAh batteries often bundled with this unit, they should be fully charged in approximately 11 to 13 hours. Charging for 24 hours is significantly longer than necessary and may lead to overcharging.Safety Warning: The manual advises that if the charger or batteries become excessively hot, you should discontinue use immediately and unplug the device.Recommended Steps:Calculate Charge Time: Divide your battery capacity (mAh) by the charger output (120mA) and multiply by 1.2. For 1300mAh batteries, unplug them after about 13 hours regardless of the light status.Check Battery Health: If the batteries are very old or damaged, they may not reach a voltage level that would trigger a light change (if your specific sub-model supports it).Manual Removal: Since the light may stay red as long as the unit is plugged in, it is best to use a timer and manually remove the batteries once the calculated time has elapsed to avoid damaging the batteries.
