Signs your laptop battery needs replacement
Not all battery problems require immediate replacement. But if you notice any of these signs, bring your device in for a free battery health check:
- Battery swelling — The trackpad feels raised, the chassis has a bulge, or the device won't sit flat. Swelling is a safety hazard requiring immediate replacement.
- Fast battery drain — Your laptop dies within 30–60 minutes on a full charge, when it used to last 4–6 hours.
- Laptop shuts down unexpectedly — The device powers off at 20–30% battery remaining, or shuts down under load even when plugged in.
- Battery not charging — The laptop only works when plugged in, or shows "plugged in, not charging" status.
- Overheating near the battery area — The bottom of the laptop gets unusually hot near the battery compartment.
- Age over 2–3 years — Lithium-ion batteries naturally degrade. If battery life has noticeably declined, a replacement restores original performance.
- Battery warning message — macOS or Windows shows "Service Battery" or "Replace your battery" warnings.
Warning: A swollen battery is a fire risk. Do not continue charging or using the device. Switch it off, place it in a cool ventilated area, and bring it to Hitech immediately for free assessment.

Types of laptop batteries
Lithium-Ion (Li-ion) batteries
Most laptops use Li-ion batteries. They offer good energy density and have no memory effect. Typical lifespan: 300–500 charge cycles (about 2–3 years of daily use). Li-ion batteries degrade naturally over time.
Lithium-Polymer (Li-Po) batteries
Modern ultrabooks and MacBooks use Li-Po batteries. They are thinner, lighter, and can be moulded into custom shapes. These have a similar lifespan to Li-ion but are more sensitive to heat. MacBook batteries are glued into the chassis and require specialist tools for removal.
