LG Gram Battery Replacement — your questions answered
How much does an LG Gram battery replacement cost in Australia?
Prices vary by screen size and watt-hour rating. A 14-inch 72Wh pack typically ranges $380-$480 while 16-inch and 17-inch 80Wh units sit between $440-$580. All replacements include cycle count reset and 90-day warranty on parts and labour.
Should I replace my LG Gram battery at 80% health?
For travellers and consultants who rely on all-day runtime, replacement at 80% is recommended. Below this threshold the laptop may shut down under moderate load and Windows power plans become unreliable during meetings or flights.
Can LG Gram batteries swell and damage the chassis?
Yes, though uncommon. Swelling lifts the trackpad and can crack internal mounts after 30-36 months of daily full cycles. Stop charging immediately, power down the unit and bring it in for same-day assessment to avoid further pressure on the motherboard.
Is LG Gram battery replacement covered under warranty?
LG factory warranty rarely covers battery wear after the first 12 months. Our 90-day warranty covers the replacement parts and labour regardless of remaining manufacturer cover, provided no liquid or physical damage is present.
How long does an LG Gram battery replacement take?
Most 14-inch and 16-inch models are completed in one to two business days. 17-inch units or units requiring connector repair may take up to three days. Onsite visits for battery health diagnostics can often be completed the same day.
