Full specifications

This battery is the direct OEM replacement, meaning it matches the original Acer battery in every way — from the BMS chip to the cell chemistry. Using a genuine pack ensures your laptop's charging circuitry stays safe and battery life readings are accurate. Aftermarket batteries often cut corners on cell quality, leading to shorter runtime or even swelling. Our tested used units have been bench-tested to perform like new, so you get reliable power without paying full retail price.

Compatibility — which laptops does this battery fit?

This 48Wh 3-cell internal battery is a direct OEM replacement for the following Acer laptops:

• Aspire 5 A515-54
• Aspire 3 A315-55
• Aspire 5 A515-44
• Swift 3 SF314
• Aspire 7 A715

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 on WhatsApp 0314 4000131 — there are often three or four interchangeable part numbers per chassis. Sayam can cross-check the part number from Acer's database to confirm fitment.

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 3-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.

Each pack is bench-tested in our workshop at Hafeez Center before it's listed. We reject any battery that shows even a 5% drop in capacity or any imbalance. This rigorous checking is why we can offer a 30-day check warranty with confidence.

Installation — how to swap the battery

Internal 3-cell batteries on modern Acer 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. For customers in Karachi, Islamabad, Rawalpindi, Faisalabad, Multan, or Peshawar, we include a printed guide with photos to make the swap easy.

Real-world battery life — what to expect

With this 48Wh 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 Acer's published specs for the listed models. If your old battery was giving you 2 hours, the new one will restore the original full runtime. Compare this to a degraded pack where lithium-ion cells have lost capacity — our tested units deliver consistent performance because we filter out high-cycle or worn-out packs.

Warranty — what you're protected against

Every battery carries our 30-day check warranty. If the pack fails to charge, shows wrong capacity in Windows/macOS, drops below 85% of rated Wh in our diagnostic, or develops any swelling within 30 days, bring it back to the shop with the invoice for full replacement or refund. No questions asked within the warranty window. This warranty covers both the original price of Rs. 9,499 and any additional services.

Frequently asked questions

Do I need to take the laptop apart to install the 3-cell battery?

Internal batteries need the back panel removed — typically 8-12 Phillips screws, then disconnect the old battery cable, swap, and reseat. We do free in-shop installation in Lahore if you bring the laptop. Removable 6-cell/9-cell batteries on older laptops just slide in/out with a latch — no tools needed.

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.

Is this a genuine OEM battery or aftermarket?

Our stock comes in both genuine Acer 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. The price on nnlaptops.com applies to the tested used original, which is a direct pull from a working laptop — no performance compromises.

How much battery backup will I get on my Aspire 5 A515-54?

With this 48Wh 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.
