Replacement Battery for Flex 2 14 and 15

This Dr. Battery Professional Series pack is a new lithium-ion unit rated at 7.2V and 4400 mAh. It matches the original Lenovo part numbers L13L4A61, L13L4E61, L13M4A61, L13M4E61, L13S4A61 and L13S4E61. Integrated circuitry protects against over-charge, over-discharge, overheating and short-circuit.

Upgrading from a Depleted Original Pack

The battery replaces a worn or failed factory cell when run-time has dropped or the laptop no longer holds a charge. Swapping is worthwhile once the original no longer meets daily mobility needs and the part number plus 7.2V rating match the label on the old unit.

For Flex 2 14 and 15 Owners Needing a Direct Swap

Buyers with a compatible Flex 2 14 or Flex 2 15 model who can verify the original part number and voltage will find a drop-in fit. Those whose laptop uses a different voltage, connector layout or part-number series should look elsewhere.

Questions about this item

Will this 8.0 x 1.5 x 0.8 cm battery fit my Lenovo Flex 2 14 without modification?

The pack measures 8.0 x 1.5 x 0.8 cm and is built to the original Lenovo form factor for the Flex 2 14 and Flex 2 15 Series, so it seats in the standard bay with no trimming or adapters.

What is the part-number match I should verify before fitting this 7.2 V replacement?

Confirm your original battery shows one of these Lenovo part numbers: L13L4A61, L13L4E61, L13M4A61, L13M4E61, L13S4A61 or L13S4E61; the DR-PRO-LLN283-A unit replaces all of them.

How long will the 4400 mAh Li-ion cells hold a useful charge before I need a new pack?

Li-ion chemistry in this capacity class typically provides several hundred full cycles before runtime drops noticeably; the built-in protection against over-charge, over-discharge and overheating helps maximise that service life.
