Pre-installation note:

Never start the engine before fully charging the new battery to avoid irreversible damage that could shorten its lifespan.

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

After production, AGM batteries are factory-activated and slowly discharge during storage. Recharge at least every 3 months.

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

Vehicle electronic devices, 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.
