A swollen battery isn't just an inconvenience — it's a safety risk that can push against the keyboard and trackpad and, in rare cases, damage the chassis. Our Dell Laptop Battery Repair Kolkata technicians remove and dispose of swollen cells correctly, then fit a properly matched replacement so you're not left guessing about compatibility or safety.

Frequently Asked Questions
Is a swollen laptop battery dangerous?
Yes. A swollen lithium-ion battery can leak or, in extreme cases, catch fire. Stop using the laptop on battery power and bring it in as soon as possible for safe removal and replacement.
Why does my Dell laptop show 'plugged in, not charging'?
This can be a battery health issue, a DC jack fault, or a charger/adapter problem. We run a quick diagnostic to identify exactly which component is at fault before quoting.
How long do replacement batteries last?
A genuine compatible cell typically lasts 2–4 years of normal daily use, similar to an original Dell battery, depending on charge cycles and usage patterns.
Can I replace the battery myself?
Some Dell models have user-replaceable batteries, but many business and premium series require opening the chassis. We recommend professional replacement to avoid damaging internal connectors.
