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.

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.
How battery replacement works at Hitech

How to extend your new battery life
- Avoid extreme temperatures -- Heat accelerates battery degradation.
- Keep charge between 20%-80% -- Lithium batteries last longest in this range.
- Use original charger -- Third-party chargers can damage the battery management system.
- Enable battery saver settings -- Both Windows and macOS have built-in power management.
- Calibrate monthly -- Let the battery drain to near empty, then charge to 100% without interruption.

Laptop battery repair or replacement?
Searching for laptop battery repair in Singapore? Most battery faults (fast draining, sudden shutdowns, "plugged in but not charging", swelling) are solved by a battery replacement — from S$100 fitted at Hitech, usually within an hour. Battery cell "refurbishment" is unreliable and short-lived; we install new genuine-grade batteries with full warranty instead, which is both safer and cheaper over time.
We service batteries for Dell, HP, Lenovo, ASUS, Acer, MSI, MacBook and more — including older models. If your battery is swollen, stop using the laptop and bring it in promptly: a swollen battery can damage the trackpad and chassis. Every job includes free diagnosis, a fixed quote and warranty on the new battery. Related services: charging-port & motherboard repair if the battery itself is fine but will not charge, and SSD upgrades to make an older laptop feel new again.
