REASONS WHY YOUR SOLAR BATTERY SWELL UP
These are Common Reasons Batteries Swell up
1. Overcharging
Charging the battery beyond its safe voltage causes heat and gas buildup.
2. Excessive Heat
High temperature (especially in poorly ventilated areas) damages battery cells.
3. Deep Over-Discharge
Draining the battery too low repeatedly weakens internal plates or cells.
4. Wrong Charge Controller or Inverter Settings
Incorrect voltage settings for battery type (lithium vs tubular).
5. Poor Battery Quality or Fake Batteries
Low-grade materials fail quickly under stress.
6. Aging Battery
Old batteries lose chemical stability over time.
7. Internal Short Circuit
Caused by manufacturing defects or physical damage.
Let me explain it the way I will explain to a house wife:
Battery is like food cooking on fire.
If you leave it too long or put too much heat, it will swell and spoil.
You should know:
- Overcharging is like cooking soup without watching it - it boils over.
- Heat is like too much fire under the pot.
- Deep discharge is like forcing someone to work without food - the body collapses
