Pre-installation note: Never start the engine before fully charging the new battery to avoid irreversible damage that will shorten its lifespan.

It is absolutely mandatory to fully charge any new AGM battery before installing it.

After manufacturing, AGM batteries are factory activated and will slowly discharge during storage.

Recharge them at least every 3 months.

They may need to be recharged sooner in higher or lower temperatures.

Vehicle electronics, such as the clock, alarm, etc., will also drain the installed battery. AGM batteries do not tolerate deep discharge well.

Keep them charged at a minimum of 12.4V for optimal performance throughout their lifespan.

Connect the battery to a suitable automatic maintenance charger when not in use for a period of time to maintain the optimal charge level.
