Common Issues: Memory effect, reduced capacity.
Nickel-Metal Hydride (NiMH) Batteries:
Repair: Replacing bad cells, recalibrating.
Common Issues: Capacity fading, self-discharge.
Alkaline Batteries:
Repair: Generally not repairable; usually replaced.
Common Issues: Leakage, corrosion.
Rechargeable Button Cells (e.g., CR2032):
Repair: Not typically repairable; replacement is recommended.
Common Issues: Voltage drop, leakage.
Industrial & VRLA Batteries:
Repair: Checking for sulfation, replacing damaged plates, electrolyte adjustments.
