A laptop battery typically lasts 300–500 full charge cycles before its capacity drops noticeably below the original rating. For a laptop used daily, this translates to 2–4 years before the battery feels significantly worse. At Xigox, battery replacement is our most common single repair — and with free doorstep pickup across Mumbai, it takes less than a day from collection to return.
When Does a Laptop Battery Need Replacing?
- Backup time below 50% of original — a laptop that used to last 6 hours now lasts 2–3 hours
- Swollen battery — the trackpad feels raised, the base of the laptop looks puffed; this is a fire safety risk and must be replaced immediately
- Not charging at all — battery shows 0% and does not increase even when plugged in (check if adapter is working first)
- Sudden shutdowns — laptop powers off at 30%, 40%, or 50% battery without warning
- Stuck at a percentage — battery shows 100% for hours then drops rapidly to 10% (calibration failure)
- Windows Battery Health alert — Windows 11 may show a red battery icon indicating capacity is critically low

OEM vs Compatible Batteries — Which Should You Choose?
OEM batteries are manufactured to the laptop brand's exact specification — same capacity (Wh), voltage, and discharge curve as the original. Compatible (aftermarket) batteries are manufactured by third parties to similar specifications at 20–35% lower cost. At Xigox, we use high-quality compatible batteries from reputable manufacturers that we have vetted for safety and capacity consistency. All batteries we install carry our 90-day Xigox warranty. For premium laptops (MacBook, XPS, ThinkPad X1), we recommend OEM-equivalent cells to maintain the laptop's designed performance envelope.
Is a Swollen Laptop Battery Dangerous?
Yes — a swollen battery is a safety hazard that must be addressed immediately. Lithium polymer batteries swell when gases accumulate due to electrolyte breakdown, often caused by overcharging, heat damage, or age. A swollen battery can rupture, catch fire, or cause chemical burns. If your laptop's trackpad is raised, the base is puffed, or you can see the battery bulging through the casing, stop using the laptop immediately and contact us for emergency same-day pickup.
How Long Does Laptop Battery Replacement Take?
For most laptop models — Dell Inspiron, HP Pavilion, Lenovo IdeaPad, ASUS VivoBook, Acer Aspire — battery replacement takes 30–60 minutes in our workshop. MacBook battery replacement takes 1–2 hours due to the adhesive strips securing the battery to the chassis. Total turnaround from pickup to return: same day (pickup in morning, return by evening) for all standard models.
What Backup Life Should I Expect After Battery Replacement?
After replacement, you should expect backup time close to the laptop's original specification. A 3-year-old Inspiron 15 that lasted 2 hours should return to 5–6 hours after a new battery is fitted. The exact backup life also depends on screen brightness, workload intensity, and background app activity. We recommend calibrating the battery after replacement — run it from 100% to below 10% in one session, then charge to 100% before using normally.
