What Are the Signs Your Laptop Battery Needs Replacement?

1. Battery swelling (immediate action required)

If the trackpad is pushing up, the bottom case has a bulge, or you hear a cracking sound when pressing on the laptop base — stop using the device immediately. A swollen lithium-ion battery is a fire risk. Do not charge it. Do not poke it. Call a technician.

BAYAS handles swollen battery replacement safely. We follow proper disposal procedures for lithium-ion cells. WhatsApp 01712-644590 for emergency service.

2. Battery dies quickly

If your laptop ran for 4 hours on a full charge when new and now dies in 30 minutes, the battery has degraded. Lithium-ion cells lose capacity over time and are accelerated by heat — which means Dhaka's tropical climate takes a toll.

3. Laptop shuts down at 20–30%

This is a calibration issue or a failing cell. The battery reports a charge level, but the actual voltage drops below the threshold needed to keep the system running. A replacement is the only real fix.

4. Battery not charging

If the battery icon shows "plugged in, not charging" or it charges only when the laptop is off, the battery may have entered protection mode (common after deep discharge) or the charging circuit on the motherboard may have failed.

5. Battery percentage jumps erratically

If your battery reads 50%, then suddenly drops to 5% without warning, one or more cells inside the battery pack have failed. A new battery pack restores accurate capacity tracking.

What DIY Checks Should You Do Before Replacing Your Battery?

Before spending money on a new battery, try these quick checks:

Check battery health in Windows

Open Command Prompt as Administrator and type:

powercfg /batteryreport

This generates an HTML report showing design capacity, full charge capacity, and cycle count. If full charge capacity is below 80% of design capacity, it is time for a replacement.

Check battery health on Mac

Click the Apple icon → System Settings → Battery. On newer macOS versions, go to System Information → Power and check "Cycle Count" and "Condition."

Industry guideline: Most laptop batteries are rated for 300–500 charge cycles (MacBooks: 1,000 cycles). Beyond that, expect reduced life.

Check for swelling

Place the laptop on a flat surface. If it rocks, the battery has swollen. On MacBooks, check if the trackpad is clicking properly — a swollen battery presses up on the trackpad from below.

Reset SMC / BIOS

Some charging issues are software-related. On Intel Macs, resetting the SMC can restore normal charging behavior. On Windows laptops, a BIOS reset or removing the battery and holding the power button for 30 seconds can discharge residual power and fix charging lockout.

If these checks do not help, professional diagnosis is needed. BAYAS technicians can run a full battery and charging circuit diagnostic as part of our laptop repair service. Battery swelling, random shutdowns at 30%, and sudden drops to 0% are three of the 8 warning signs that mean your laptop needs professional repair — do not ignore them.

Genuine / OEM batteries

Pros: Matches original specifications, safe, reliable, full capacity
Cons: More expensive
Warranty: 6–12 months
Source: Authorized distributor or OEM

Grade-A compatible batteries

Pros: Good quality, meets or exceeds OEM specs, well-tested
Cons: Branding not original
Warranty: 6–12 months
Source: Reputable third-party manufacturers (e.g., Green Cell, KingSener)

Cheap / counterfeit batteries

Pros: Cheapest option (BDT 1,000–2,000)
Cons: Untested cells, incorrect capacity labels, no safety protection circuit, risk of swelling and fire
Warranty: None
Source: Unlabeled, no brand, sold on Facebook Marketplace

Bottom line: A BDT 1,500 battery that swells in 3 months and damages your laptop chassis is not a deal — it is a liability. BAYAS uses only genuine or grade-A batteries from trusted suppliers.

How to Compare Battery Replacement vs Buying a New Laptop

Use this decision table to guide your choice:

Situation	Laptop age	Repair cost	Recommendation
Battery only failing, laptop fast	Under 4 years	BDT 3,300–8,500	✅ Replace battery
Battery + keyboard failing	Under 3 years	BDT 5,000–12,000	✅ Replace both
Battery failing, laptop very slow	5+ years	BDT 3,300–22,000	Consider new laptop
Battery swollen + motherboard issues	Any age	BDT 8,000+	New laptop likely better
MacBook in good condition	Under 5 years	BDT 8,500–22,000	✅ Replace battery (Macs last 7+ years)

General rule: If the repair cost is under 40% of the laptop's current resale value, repair is worth it. For a 3-year-old HP worth BDT 25,000, a BDT 5,000 battery replacement makes financial sense.

What Is the Laptop Battery Replacement Process at BAYAS?

Step 1: WhatsApp your laptop model

Send your brand, model name, and battery symptom to 01712-644590. Include a photo of the battery indicator if possible.

Step 2: Get a quote

We reply within 30 minutes with the battery price (genuine and compatible options), labor cost, and available time slots.

Step 3: Home visit

Our technician arrives at your home or office with the battery, tools, and anti-static equipment.

Step 4: Diagnosis confirmation

We run a battery health check to confirm replacement is needed. If the issue is actually a charging circuit fault on the motherboard, we explain the difference and adjust the plan. For chip-level charging port repair, see our motherboard repair service.

Step 5: Replacement

Non-glued batteries (most Windows laptops): The battery is unscrewed, disconnected, and replaced. Takes 15–30 minutes.
Glued batteries (MacBooks, some ultrabooks): The battery adhesive is carefully dissolved, the old battery removed, and the new one installed. Takes 45–90 minutes.

Step 6: Calibration and test

We charge the new battery to 100%, run a discharge test, and verify health reporting. You confirm everything works before payment.

What Are the Dhaka-Specific Battery Issues?

Heat degrades batteries faster

A lithium-ion battery's life is measured at 25°C. At 35°C (a normal Dhaka afternoon), battery degradation doubles. At 40°C+ (inside a laptop running under load in an uncooled room), degradation accelerates even more.

Tip: Keep your laptop on a hard surface (not a bed or pillow) to allow heat to escape. Consider a cooling pad during Dhaka summers. See our computer maintenance service for preventive care.

Power surges kill charging circuits

During load-shedding cycles, power flickers on and off. Cheap UPS units and surging voltage can damage the charging IC on your laptop's motherboard — making it look like the battery is dead when the real fault is on the board. For power backup protection, see our UPS repair service.

BAYAS technicians always test the charging circuit before replacing a battery. We serve all areas including Dhanmondi, Gulshan, and Banani. If the motherboard charging IC is the problem, our chip-level motherboard repair fixes it without replacing the entire board.

Counterfeit batteries flood the market

Facebook Marketplace and unlabeled shops sell batteries that claim 56 Wh capacity but deliver 18 Wh. Worse, these batteries often lack the protection circuit board (PCB) that prevents overcharging and short circuits — creating a genuine fire hazard.

Frequently Asked Questions

How much does laptop battery replacement cost in Dhaka?

Laptop battery replacement in Dhaka costs BDT 3,300–22,000 depending on brand and model. HP, Dell, and Acer standard laptops cost BDT 3,300–5,700 installed. MacBook Air costs BDT 8,500–17,000; MacBook Pro costs BDT 11,000–22,000. WhatsApp BAYAS at 01712-644590 for a model-specific quote.

How long does a laptop battery last in Dhaka?

In Dhaka's climate, most laptop batteries last 18–30 months before noticeable degradation. With good habits (avoiding 100% charge constantly, keeping the laptop cool), you can extend this to 2–3 years. MacBook batteries rated for 1,000 cycles typically last 3–5 years even in Dhaka's heat.

How much does a laptop battery cost in Dhaka?

Standard Windows laptop batteries cost BDT 2,500–5,500 for the battery part alone (before labor). MacBook batteries cost BDT 7,000–18,000 depending on model. Total installed price includes BDT 800–3,000 for labor. See the full price table above for brand-specific pricing.

Can I replace my laptop battery myself?

On older laptops with removable batteries, yes — it is an easy swap. On modern laptops with glued-in batteries (most ultrabooks and all recent MacBooks), DIY replacement carries real risk. The adhesive is strong, the battery is fragile, and puncturing a lithium-ion cell causes a fire. We recommend professional service for glued batteries.

Do you replace laptop batteries at home in Dhaka?

Yes. BAYAS provides laptop battery replacement at your home across all 36 Dhaka zones including Uttara, Gulshan, Dhanmondi, Mirpur, and Banani. Most replacements complete in under 60 minutes.

Will a new battery make my laptop faster?

No — a new battery only affects battery life and charging behavior. If your laptop is slow, the issue is likely storage, RAM, or thermal throttling. See our computer upgrade service for performance solutions.

What should I do with my old laptop battery?

Do not throw it in the trash. Lithium-ion batteries contain hazardous materials. BAYAS accepts old batteries for safe disposal when we install a new one.

My laptop charges but dies quickly on battery — is it the battery?

Almost certainly yes. If the laptop runs fine while plugged in but dies quickly on battery, the cells have degraded. If it also shuts down while plugged in under load, the problem may be the charger, motherboard, or battery together — a diagnostic is needed.

Is laptop battery replacement worth it in Bangladesh?

Yes — if your laptop is under 4–5 years old and otherwise working well, battery replacement is almost always worth it. Replacing a battery at BDT 3,300–5,700 is far cheaper than buying a new laptop at BDT 25,000+. The exception is if other components (motherboard, screen) are also failing.

How long does laptop battery replacement take at BAYAS?

Non-glued Windows laptop batteries take 15–30 minutes. Glued-in batteries (MacBooks and premium ultrabooks) take 45–90 minutes. The technician comes to your home — no shop visit needed.

What brands of laptop battery does BAYAS replace?

BAYAS replaces batteries for HP, Dell, Lenovo, ASUS, Acer, MSI, Toshiba, Samsung, Xiaomi, Huawei, and all Apple MacBook models (Air and Pro). We use genuine OEM or grade-A compatible batteries with 6–12 month warranty.
