- Ensure batteries are correctly inserted into the charger slots.
- Check if the battery contacts are clean and free of debris.
- If a battery is severely depleted, it may take a few minutes for the charger to recognize it.
- If the battery is old or damaged, it may no longer hold a charge.
- Short battery life:
- Ensure batteries are fully charged before use.
- Battery capacity naturally degrades over time and with usage cycles.
