Questions about this item

How do I install the GU230 battery in my LG KF390, and which step do people often miss?

Power off the phone, remove the back cover, lift out the old cell, align the gold contacts on the new GU230 with the terminals in the compartment, press it down until it sits flat, then replace the cover. The step often missed is checking that the 54.82 x 33.93 x 4.66 mm pack sits completely flush before snapping the cover back.

What maintenance or replacement will the GU230 battery need over time?

The 650mAh lithium-ion cell will gradually hold less charge; when talk time becomes too short for daily use, replace it with another GU230 unit certified to ISO9001, RoHS and CE.
