OPTIMA O804250000 Starting Battery

Compatibility

The OPTIMA O804250000 starting battery is an advanced AGM device designed for reliability in harsh conditions. Due to the nature of the marine parts market, compatibility must be verified by the manufacturer's catalog number (O804250000) or OE number. We do not recommend assuming fitment for specific engine brands without prior verification. If you have doubts about selecting the right battery for your equipment, we strongly advise contacting our support team to find the perfect solution.

Installation, Setup, and Maintenance Tips

Installing an OPTIMA battery requires strict adherence to safety rules. The device is sealed and vibration-resistant, making it ideal for boats, but correct polarity connection is crucial. The positive terminal is marked as standard (L+). Before installation, ensure the battery holder is stable and the 10.5 mm foot provides secure seating. Regularly check the voltage, and for long periods of inactivity, consider using a maintenance charger to extend cell life.
