Signs your laptop battery needs replacing

Not every charging issue means you need a new battery. Here's how to tell the difference:

1. Rapid battery drain

Your laptop used to last 4–6 hours. Now it dies in under 90 minutes — even with light use like browsing and email. This is the most common sign of battery degradation. Lithium-ion batteries lose capacity with every charge cycle; after 300–500 full cycles, most batteries hold less than 80% of their original capacity.

2. Battery percentage jumps or is inaccurate

One minute it says 40%, the next it's 5%, then back to 25% after a reboot. This erratic behaviour means the battery's internal controller is failing — it can no longer report its true charge level.

3. Laptop won't charge at all

If your laptop only works when plugged in and dies instantly when you unplug the charger, the battery has failed completely. This can also be a charging port or motherboard issue, so get a proper diagnosis before buying a replacement.

4. Overheating during charging

If the bottom of your laptop gets uncomfortably hot near the battery area while charging, the battery may be developing internal shorts. Stop using it and bring it in for inspection immediately.

5. Swollen or bulging battery — DANGER SIGN

If your trackpad is lifting, your keyboard is bulging, or the bottom case is no longer sitting flat, your battery is swelling. This is a fire hazard. Power off the laptop immediately. Do not charge it. Do not pierce or press on the bulge. Bring it to a repair shop the same day.

Swollen lithium-ion batteries can rupture and catch fire. This is the one battery issue you should never wait on.

Quick self-check: On Windows, open Command Prompt and type powercfg /batteryreport to generate a detailed battery health report. On Mac, hold Option and click the battery icon → look for "Condition: Replace Soon" or "Service Battery."

Laptop battery replacement cost in Singapore (2026)

Prices vary by brand, model, and whether you choose an OEM (original) or third-party battery. Here's what to expect:

BrandOEM BatteryThird-Party (Grade A)Typical LabourTotal (OEM)
Dell$80 – $150$50 – $80$30 – $50$110 – $200
HP$70 – $140$45 – $75$30 – $50$100 – $190
Lenovo$65 – $130$40 – $70$30 – $50$95 – $180
ASUS$70 – $140$45 – $75$30 – $50$100 – $190
Acer$60 – $120$35 – $65$30 – $50$90 – $170
MacBook (pre-M1)$120 – $200$80 – $120$40 – $60$160 – $260
MacBook (M1/M2/M3)$180 – $280N/A (integrated)$50 – $80$230 – $360
Microsoft Surface$100 – $180$60 – $100$50 – $80$150 – $260
Gaming laptops$80 – $180$50 – $100$30 – $50$110 – $230

Why the range? Older and business-class laptops (ThinkPad, Latitude, EliteBook) tend to have more affordable and widely available batteries. Slim ultrabooks and newer MacBooks use glued-in or integrated batteries that cost more in both parts and labour. Gaming laptops often use higher-capacity batteries that naturally cost more.

At Hitech Computer & IT Solutions, we source either original OEM batteries or Grade-A third-party cells with full calibration and a 90-day warranty. Free diagnosis before you commit.

OEM vs third-party batteries: which should you choose?

FeatureOEM BatteryGrade-A Third-Party
Compatibility100% guaranteed95%+ (tested before install)
Battery lifeMatches original specs85–95% of original
Warranty1 year (manufacturer)90 days (shop)
PriceHigher30–50% cheaper
SafetyHighest standardGood (if from reputable supplier)
AvailabilityMay need to order (3–7 days)Usually in stock

Our recommendation: For MacBooks and premium ultrabooks, go OEM — the integrated battery design makes third-party cells riskier. For standard laptops (Dell, HP, Lenovo, ASUS, Acer), a Grade-A third-party battery from a trusted repair shop saves you money with near-identical performance and the same warranty protection.

Watch out for: Ultra-cheap batteries ($20–$30) from online marketplaces. These often use recycled cells, have no safety certifications, and can swell or fail within weeks. A $25 battery that damages your $1,500 laptop is not a bargain — it's a liability.

How long does a battery replacement take?

Most standard laptop battery replacements take 30–60 minutes from drop-off to pickup. That includes removing the old battery, installing the new one, calibrating it with a full charge-discharge cycle, and running a health check.

For MacBooks and ultrabooks with glued-in batteries, expect 1–2 hours — the adhesive needs to be carefully dissolved and the new battery properly seated. We never rush this step; a poorly installed battery is a safety risk.

When you bring your laptop to Hitech, we do a free diagnosis first. Sometimes the issue isn't the battery at all — it's a faulty charging port, a bad power adapter, or a motherboard problem. We'll tell you honestly what needs fixing and give you a firm quote before any work begins.

What happens during a professional battery replacement

  1. Diagnosis (free): We test your current battery's health and confirm it's the source of the problem — not the charger, charging port, or motherboard.
  2. Removal: The old battery is disconnected and removed. For swollen batteries, we follow strict safety procedures.
  3. Installation: The new battery is connected and secured. All screws, clips, and adhesive (if applicable) are properly applied.
  4. Calibration: We run a full charge cycle and verify the battery reports correctly to the operating system.
  5. Testing: Boot test, charge test, discharge test, temperature check. You get a working laptop with a battery that actually lasts.
  6. Warranty: 90 days on parts and labour. If anything goes wrong with the battery in that period, we replace it.

Frequently asked questions

How do I know if my battery is the problem and not the charger?

Try a different charger first — many "battery problems" are actually dead power adapters. If a known-working charger doesn't help, bring the laptop in. Our free diagnosis will identify whether it's the battery, charging port, or motherboard within 15–20 minutes.

Can I replace the battery myself?

Technically yes, if you have the right tools and your laptop has a removable battery (many older and business-class models do). For modern ultrabooks, MacBooks, and gaming laptops with internal batteries, we strongly recommend professional replacement. One wrong pry or punctured cell can cause a fire.

Will a new battery make my old laptop faster?

A new battery won't increase processing speed, but it can eliminate performance throttling. Many laptops deliberately slow down when the battery is degraded or missing to prevent sudden shutdowns. Replacing the battery often restores full performance because the system stops throttling.

How long will a replacement battery last?

A quality replacement battery should last 2–4 years with normal use (300–500 full charge cycles). To maximize lifespan: avoid keeping your laptop plugged in at 100% constantly, don't let it drain to 0% regularly, and keep it away from extreme heat.

Do you replace batteries for all brands?

Yes. We stock or can order batteries for Dell, HP, Lenovo, ASUS, Acer, Apple MacBook, Microsoft Surface, Razer, MSI, LG Gram, Huawei, Samsung, and most other laptop brands. If the battery is older or rare, we'll source it and give you an ETA.

What if my battery is swollen?

Stop using the laptop immediately. A swollen battery is pressurized and can rupture. Do not charge it. Do not press on it. Bring it to us — we handle swollen batteries following strict safety protocols with proper containment and disposal.

Is battery replacement covered under warranty?

The replacement battery itself carries a 90-day warranty for parts and labour. If your laptop is still under the manufacturer's warranty, check with the brand first — Apple, Dell, and Lenovo may replace the battery for free if it's a manufacturing defect (not normal wear).

How much does diagnosis cost?

Diagnosis is completely free at Hitech. We'll check your battery, charger, and charging circuit and tell you exactly what needs fixing — with a firm price — before any work starts. If you decide not to proceed, there's no charge.
