Note prior to installation: 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 installation.

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

It may be necessary to recharge it sooner if the temperature is higher or lower.

The vehicle's electronic devices, such as the clock, alarm, etc., also drain the installed battery.

AGM batteries do not tolerate excessively deep discharge well.

Keep them charged to 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 while to maintain the optimal charge level.

Fits: 80-96 FLT/Touring
