If you own an affected battery, or are in doubt, immediately contact LG Energy Solution Australia on 1300 677 273 or email productau@lgensol.com to arrange an inspection. All affected batteries will be replaced for free.  

To reduce the risk of fire until the batteries are replaced, LG Energy Solution is applying a software upgrade for affected RESU-branded ESS units to prevent them from charging beyond 75% of their maximum capacity.

LG Energy Solution has been applying and will continue to apply this upgrade remotely for certain online RESU10H Type-R, RESU10H Type-R (Secondary) and RESU7H Type-R units with sufficient connectivity. For the remaining affected RESU-branded ESS units that cannot receive the software upgrade remotely, LG Energy Solution Australia will organise a site visit to apply the upgrade.

If you are unsure whether your unit can be upgraded remotely, contact LG Energy Solution Australia on 1300 677 273 or email productau@lgensol.com.
