What this battery replaces

This kolitt replacement battery uses Li-ion chemistry at 11.1 V with a 2200 mAh capacity and 24 Wh energy rating across three cells. It carries part numbers A31N1519 and 3ICR19/66 and is built for ASUS X540, X540S, X540L, X540LA, X540LA-SI302, X540SA, X540SC, X540LJ, X540YA, R540L, R540SA and R540L series laptops. Each unit is tested for voltage accuracy, circuit protection, stable current and low self-discharge and holds CE, FCC and RoHS certifications.

Who should buy this and who should not

Owners of the listed ASUS models needing a direct 11.1 V, 2200 mAh replacement will find the correct fit and certified safety profile here. Buyers whose laptops require a different voltage, a higher capacity pack or a different physical form factor cannot use this unit. The design targets the specific part numbers shown and does not suit other series or brands.

Cycle life as the deciding spec

The manufacturer rates the pack at about 500 recharge cycles over its service life, giving a concrete measure of long-term usability for daily charging routines. This figure lets you gauge how many full charge-discharge periods to expect before capacity drops noticeably. If your workload demands significantly more cycles, you will need to plan for an earlier replacement.

Questions about this item

How many recharge cycles will the A31N1519 battery last before it needs replacing?

The Li-ion pack is rated for about 500 recharge cycles over its life, after which capacity will drop enough to require a replacement.

What limits runtime during a long work session with the 3-cell 2200mAh pack?

The 24 Wh capacity is the first limit; once the stored energy is used the laptop must be plugged in to continue.

Does the 11.1 V battery run hot or draw extra power when the laptop is on all day?

It is tested for correct voltage, circuit protection and stable current with low self-discharge, so heat and power draw stay normal during continuous use.
