Replacement battery for Laresar L6 Pro

This 14.4V lithium pack is built to the original specifications for the Laresar L6 Pro robot vacuum. It delivers a 5200mAh capacity and 74.88Wh energy rating. The unit includes overcharge, over-discharge, over-voltage and short-circuit protection. It is certified to ISO9001, RoHS, CE, UN38.3 and MSDS standards.

Upgrading from a depleted original pack

The battery replaces the factory cell when run-time has dropped or the vacuum no longer holds a charge. A swap is worthwhile when cleaning cycles finish early or the dock reports a charging fault. The 1-pack format restores the original 5000mAh design capacity with a tested 5200mAh rating. No higher-capacity alternative is offered in this listing.

Check model and part number before ordering

Verify that your robot is the L6 Pro and compare the part number on your old battery to the compatible list. The physical size is 136.6 x 37.6 x 37.3mm and the weight is 580.0g; confirm the battery bay accepts these dimensions. This unit fits only the models explicitly named by the supplier.
