Recall Update: LG Energy Solution Announces Expansion of Existing Free Replacement Program Due to Risk of Fire in Certain Energy Storage System (ESS) Home Batteries

The voluntary recall and free replacement program covers ESS Home Batteries containing cells manufactured between April 2017 and September 2018, and expands existing replacement programs underway in certain markets (please refer to https://www.lgessbattery.com/us/home-battery/news-view.lg?blcSn=1233&devonTargetRow=1&devonOrderBy=&searchType=all&searchKey= for the existing replacement program underway). LG Energy Solution will cover the costs related to this replacement program.

LG Energy Solution has announced the recall and free replacement program following reports from the field about overheating incidents linked to certain ESS Home Batteries. LG Energy Solution will undertake inspections and replacement of the potentially affected ESS Home Batteries and will also implement safety-enhancing upgrades for the battery management and control software. In conducting this voluntary replacement program, LG Energy Solution is fully cooperating with the Consumer Product Safety Commission.

Jong Hyun Kim, President of LG Energy Solution, said, "customer safety and product quality are our highest priority. With this announcement, LG Energy Solution will further enhance the safety of our products in our bid to make the world's safest batteries."

Replacement Scope and Details

LG Energy Solution's replacement program will provide free replacement batteries which incorporate manufacturing process improvements that are designed to further enhance the safety of ESS Home Batteries. LG Energy Solution, in cooperation with its partners, will contact potentially affected customers to arrange for the replacement, and all proposed safety measures will take place following such consultation with customers.

Where possible and before the replacement is completed, LG Energy Solution will also implement remote modifications to the potentially affected ESS Home Batteries to reduce the potential for overheating until replacement is complete.
