Direct replacement for LG handsets

Two new LG BL-53QH lithium-ion cells deliver 2100 mAh each, matching the original specification for the Optimus L9 P769, 4X HD P880 and Escape P870. The OEM chemistry ensures proper voltage regulation and charge-cycle behaviour without modification.

Twin-pack convenience

The pair lets you keep one battery in the phone and a fully charged spare in a bag or desk drawer, eliminating downtime while the depleted cell recharges. No cables, docks or adapters are included in the pack.

Suits owners of the listed LG models

Users of other LG handsets or different brands should verify the exact model code before purchase, as the BL-53QH form factor and connector are not universal across the range.

Questions about this item

When should the 2100 mAh Li-Ion cells be replaced?

Replace them when runtime drops noticeably or the phone shuts down before the indicator reaches zero, typical after several hundred charge cycles.

What limits runtime during continuous heavy use?

The 2100 mAh capacity sets the hard ceiling; sustained high drain will deplete the cell faster than light use.

Do the batteries get hot during all-day operation?

Li-Ion chemistry stays cool under normal loads; only heavy continuous discharge or charging generates noticeable warmth.
