Genuine Lenovo Legion 5 / Y540 80Wh Battery – Restore Your Gaming Laptop's Full Runtime
If your Legion 5 or Y540 now dies after an hour of FIFA or a single Netflix movie, the original battery is likely worn out. The Lenovo Legion 5 / Legion Y540 80Wh 4-Cell Gaming Battery (L19C4PC0) brings back the factory runtime you paid for. Priced at Rs. 15,899 at N.N Laptops in Hafeez Center, Gulberg III, Lahore, this is the exact replacement your laptop needs – we bench-test every unit so you know it delivers 95%+ of rated capacity before it leaves our shop. WhatsApp 0314 4000131 with your laptop model and we'll confirm fitment in seconds.
What Sets This Battery Apart
This 80Wh, 15.36V, 4-cell internal pack is built to Lenovo's OEM spec. It's not a cheap aftermarket cell that degrades after 50 cycles – our batteries (both genuine pulls and high-grade A-class compatibles) are tested for cell balance, cycle count (under 100), and charge/discharge performance. Every battery is bench-tested before listing, and we offer a 30-day check warranty against failure, swelling, or wrong capacity readings. Whether you're in Karachi, Islamabad, Rawalpindi, Lahore, or Faisalabad, we deliver nationwide via TCS or Leopards with same-day delivery in Lahore – order through nnlaptops.com or drop by the shop.
Compatibility – Which Laptops Fit?
This battery is a direct OEM replacement for: Legion 5 15ARH05, Legion 5 15IMH05, Legion Y540, Legion Y545, Legion 5 Pro, and other models using the L19C4PC0 part number. Always match the part number on your old battery sticker before ordering. If your laptop is listed but the battery part is different, message me on WhatsApp 0314 4000131 – I'll help you find the right pack.
Real-World Performance
With a fresh 80Wh battery, expect 5-7 hours of web/office work, 6-8 hours of video playback, around 2-3 hours for coding or Photoshop, and 60-90 minutes of gaming – exactly what your Legion delivered when new. These numbers are consistent across all compatible models. If your current battery gives you less than 2 hours, this replacement will bring back full factory runtime immediately after calibration.

Frequently Asked Questions
How long does this battery last per charge?
With this 80Wh pack on balanced Windows settings, 70% brightness and Wi-Fi on, you'll get 5-7 hours mixed use (web, Office, video). Gaming or heavy GPU load reduces it to 60-90 minutes – typical for any gaming laptop.
Will my laptop recognise this battery?
Yes – our batteries are BMS-flashed with correct ID, so Windows, Lenovo Vantage, and battery health tools show proper cycle count and capacity. No 'plugged in, not charging' errors.
How many cycles will it last?
400-600 full cycles (2-3 years of daily use) before capacity drops noticeably. Keep the battery between 40% and 80% for longest life – avoid leaving it plugged in at 100% continuously.
