The Lenovo ThinkPad T480 24Wh 2-Cell Internal Battery (Genuine 01AV489) is a genuine, tested Lenovo replacement battery available at N.N Laptops, Hafeez Center, Lahore for Rs. 8,500.

Why choose this 24Wh battery?

This 24Wh internal battery is ideal for users who prioritise portability and light weight. It’s significantly lighter than the larger 48Wh or 72Wh options, making it perfect for everyday commutes and short work sessions. If you use your ThinkPad T480 mostly for web browsing, Office tasks, and video streaming, this pack gives you 5–7 hours—more than enough for a typical day. For heavy workloads, you can combine it with the external battery bridge (sold separately) to double your runtime without carrying a bulky single pack.

Full specifications

All batteries we sell are bench-tested to ensure they meet or exceed OEM performance. The 01AV489 is a direct replacement for original Lenovo part numbers including FRU 01AV489, 01AV490, and 01AV491.

Compatibility — which laptops does this battery fit?

This 24Wh 2-cell internal battery is a direct OEM replacement for the following Lenovo laptops:

• ThinkPad T480
• ThinkPad T470
• ThinkPad T570
• ThinkPad T580

Match the OEM part number on the sticker of your current battery before ordering. If your old battery part number isn't on this list but the laptop is, message us — there are often three or four interchangeable part numbers per chassis. Common FRUs include 01AV489, 01AV490, 01AV491, SB10K97561, and SB10K97562. If you're unsure, send a photo of your old battery to Sayam on WhatsApp 0314 4000131, and we'll cross-check within minutes.

Battery health — what we test before shipping

Every battery on our shelf goes through a 5-point test before listing:

• Capacity — we measure actual usable Wh and only ship packs at 95%+ of rated capacity.
• Cycle count — read from the embedded BMS chip; we don't sell anything over 100 cycles.
• Cell balance — all 2-cell internal cells within 50mV of each other.
• Charge/discharge cycle — verified full cycle without thermal anomaly.
• Visual — no swelling, no bulging, no scorched contacts.

We source our stock from reputable suppliers in Pakistan and abroad. Most units are genuine Lenovo pulls from laptops we've upgraded, tested thoroughly before listing. Each battery is bench-tested, and the BMS is verified to communicate correctly with Windows/Lenovo Vantage.

Installation — how to swap the battery

Internal 2-cell batteries on modern Lenovo laptops require opening the back panel (8-12 Phillips screws, sometimes Torx T5). Disconnect the AC adapter, unscrew the panel, locate the battery connector on the board, gently lift the ribbon connector latch, unscrew the battery hold-down screws, lift out the old pack, and reverse the steps with the new one. Total time: 10-15 minutes.

Free installation in shop

If you're in Lahore, bring the laptop to Hafeez Center — installation is free with battery purchase. We'll also calibrate the new pack (full charge → full discharge → full charge) so Windows / macOS reads the correct capacity from day one.

After installation, allow the battery to complete two full charge/discharge cycles for optimal performance. Avoid deep discharges below 10% regularly to extend lifespan.

Real-world battery life — what to expect

With this 24Wh pack and balanced Windows / macOS settings (70% brightness, Wi-Fi on, mixed use), expect:

• Web + Office work: 5-7 hours
• Video playback: 6-8 hours
• Code compilation / Photoshop: 2-3 hours
• Gaming or heavy GPU load: 60-90 minutes

These figures match Apple / Dell / HP / Lenovo published specs for the listed models. If your old battery was giving you 2 hours, the new one will restore the original full runtime. For longer sessions, pair this internal battery with the ThinkPad T480's external battery bridge (24Wh or 48Wh) to reach 10+ hours of mixed use—ideal for travel between Karachi, Islamabad, or Lahore.

Battery life tips

To maximise cycle life, keep the battery between 40% and 85% most of the time. Avoid leaving it plugged in at 100% for days. Use Lenovo Vantage's conservation mode if you use the laptop docked often. A well-maintained battery can last 2-3 years before noticeable degradation.

Frequently asked questions

Is this a genuine OEM battery or aftermarket?

Our stock comes in both genuine Lenovo pulls (tested cells, original casing, often the higher price) and high-grade A-class compatible cells (tested for capacity at 95%+ of rated Wh). Tell us which you want on WhatsApp 0314 4000131 — both carry the same 30-day check warranty.

How much battery backup will I get on my ThinkPad T480?

With this 24Wh pack at default Windows balanced settings, expect 5-7 hours of mixed-use battery life (web, Office, video). Brightness at 70%, Wi-Fi on, no heavy GPU workload. Gaming or compiling drains in 90-120 minutes — that's normal for any laptop battery this size.

How long will the new battery last?

A fresh quality cell-pack should give you 400-600 full charge cycles (about 2-3 years of daily use) before noticeable capacity drop. Avoid leaving the laptop plugged in at 100% all day — keep it cycling between 40% and 85% for longest cell life.

Will the laptop recognise this battery in Windows / macOS?

Yes — every battery we sell is BMS-flashed with the correct cell-pack ID for the laptop, so Windows / Lenovo Vantage / Dell Power Manager / macOS Battery Health show full information including cycle count and design capacity. No 'plugged in, not charging' driver errors.

Can I use this battery with the ThinkPad T480's external battery bridge?

Absolutely. The T480 supports a dual-battery system: this internal 24Wh pack plus an external 24Wh or 48Wh bridge battery (sold separately). Windows automatically manages both, prioritizing the external one first for hot-swapping. This setup is popular among professionals who need all-day battery life for work across Karachi, Islamabad, and Faisalabad.
