Batteries don't die suddenly — they show warning signs. If you notice any of these, it's time to act.
The 5 warning signs
- Backup time dropping: If your UPS used to give 4 hours and now gives 1 hour, the battery is failing.
- Swollen battery case: This is dangerous. Stop using it immediately and replace.
- Takes too long to charge: A healthy battery charges in 4-6 hours. If it takes 10+, internal cells are damaged.
- Smells bad or leaks: Only happens with lead-acid. Replace right away.
- Gets very hot while charging: Bad sign for any battery type.
For lithium batteries, a simple capacity test at our Lahore office takes 15 minutes and is free for our customers.
Can it be repaired?
Lead-acid batteries — usually not worth the cost. Lithium packs — yes, often individual cells can be replaced if caught early. Bring it to us and we'll check.
