New L18L3PF3 L18L3PF2 Battery for Lenovo Ideapad S340-14 S340-15 C340

New L18L3PF3 / L18L3PF2 Battery for Lenovo IdeaPad S340-14, S340-15, C340 – Restore Your Laptop’s Original Runtime

Exact replacement for Lenovo part numbers: L18L3PF3, L18L3PF2 (interchangeable). Compatible with IdeaPad S340-14, S340-15, C340-14, C340-15 (and select S340/C340 variants).

You chose the IdeaPad S340 or C340 because it looks great, performs well, and has a long battery life. It's perfect for classes, work, or Netflix. But after a couple of years, that battery doesn’t hold up. It dies at 30%, jumps from 60% to 10% in seconds, or you notice the trackpad getting stiff—a sign of swelling.

The L18L3PF3 / L18L3PF2 is a high-density battery. It usually has 36Wh, but this can vary by model. When new, it gave you 6–8 hours of mixed use (web, Office, video). Now you might get 2–3 hours. You don’t need a new laptop – just a fresh, reliable battery.

This new genuine battery matches the original in performance and safety. Plus, it costs less.

Quick Specs – What You’re Getting

A healthy L18L3PF3 / L18L3PF2 battery restores your IdeaPad to its original all‑day stamina – perfect for school, remote work, or travel without hunting for an outlet.

OEM vs. Genuine Replacement vs. Cheap Generic – What’s the Real Difference?

Not every battery that fits your S340/C340 is safe or reliable. Here’s how the three options compare.

 Important for S340 / C340 owners
These laptops have thin, sealed chassis. A cheap generic battery can swell, pushing against the trackpad, keyboard, or even the screen – causing permanent damage. Our genuine‑spec battery uses the same safety circuits and precise dimensions as Lenovo’s original.

3 Signs Your IdeaPad Needs a New Battery

1. Shortened runtime – Used to last a full workday. Now you’re recharging after only 2–3 hours of light use (email, web).

2. Sudden shutdown – The laptop powers off when unplugged, even with 20–30% battery remaining.

3. Physical swelling – The trackpad becomes hard to click, the bottom case bulges, or the laptop no longer sits flat. Replace immediately – a swollen lithium battery is a fire hazard and can destroy your laptop.

If your IdeaPad is more than 2–3 years old or showing any of these signs, replace the battery now. It’s far cheaper than buying a new laptop.

Frequently Asked Questions (FAQ)

Q: Will this battery work with my Lenovo IdeaPad S340-14, S340-15, or C340?

Yes. L18L3PF3 and L18L3PF2 are the official batteries for these models. Check your current battery label – if it matches either number, this is the direct replacement. Some S340-14API (AMD) and S340-15API also use the same battery.

Q: Are L18L3PF3 and L18L3PF2 interchangeable?

Yes. They have identical voltage, capacity, connector, and dimensions. Lenovo uses multiple FRUs for the same physical battery. Either will work perfectly.

Q: Can I install this battery myself?

Yes, but it requires opening the laptop. The S340/C340 have a removable bottom cover (Phillips screws). Disconnect the battery cable (use a plastic tool), remove the old battery (held by screws), install the new one, and reconnect. If you’re comfortable with basic repair, follow a YouTube guide. If not, any local repair shop can do it in 10–15 minutes. We include a screwdriver and spudger with every battery.

Q: How long does a full charge last after replacement?

6–8 hours of typical productivity (web, Office, streaming). More demanding tasks (video calls, light gaming) may reduce runtime. You’ll get back to the original battery life when the laptop was new.

Q: Does this battery support Lenovo Rapid Charge?

Yes. When used with a genuine Lenovo 45W or 65W USB‑C adapter, it will charge to about 80% in about one hour. Enable Rapid Charge in Lenovo Vantage if available.

Q: Is this battery safe for air travel?

Yes. At under 60Wh (52–57Wh), it’s well under the FAA 100Wh limit for carry‑on luggage. Always keep spare batteries in carry‑on, never checked, and protect terminals from shorting (use original packaging or tape over contacts).

Q: What if my laptop doesn’t recognize the battery?

First, plug in the charger and let it charge for 2 hours. Then restart. If still not recognized, check that the connector is fully seated. In rare cases, a BIOS update (available from Lenovo Support) resets the battery controller. If none works, contact us for a replacement under warranty.

Q: Do you offer discounts for multiple batteries (e.g., for schools or IT departments)?

Yes. For orders of 5+ batteries, contact us for a quote. We work with businesses, schools, and repair centers.
