Understanding Battery Venting:
While OPTIMA AGM batteries are sealed and maintenance-free, all lead-acid batteries, including AGM, have provisions for venting gases in severe overcharging situations. This is a safety feature to prevent pressure buildup. Ensure the battery's vent ports are not obstructed during installation.
3. Pautas de funcionamiento
The OPTIMA YellowTop battery is designed for optimal performance in both starting and deep-cycle applications. To maximize its lifespan and ensure consistent power delivery, adhere to the following guidelines:
- Uso regular: For vehicles that are not used daily, consider using a compatible battery maintainer to keep the battery fully charged.
- Evite la descarga profunda: While the YellowTop is a deep-cycle battery, repeatedly discharging it below 10.5 volts can shorten its lifespan.
- Carga adecuada: Use a charger designed for AGM batteries. Avoid using chargers that are not regulated or that deliver excessive voltage.
- Accessory Load Management: Be mindful of the electrical load from accessories, especially when the engine is off, to prevent excessive discharge.
4. Mantenimiento
One of the primary benefits of the OPTIMA YellowTop AGM battery is its maintenance-free design. Unlike traditional flooded batteries, it does not require water additions. However, some general care practices will help ensure its longevity:
- Mantenga las terminales limpias: Periodically inspect battery terminals for corrosion and clean them if necessary using a wire brush and a mixture of baking soda and water. Rinse with clean water and dry thoroughly.
- Comprobar conexiones: Ensure all cable connections to the battery terminals remain tight and secure. Loose connections can lead to poor performance and heat buildup.
- Battery Tray Inspection: Check the battery tray for any signs of damage or corrosion. Ensure the battery is securely held in place to prevent vibration damage.
- Almacenamiento: If storing the battery for an extended period, ensure it is fully charged and then disconnect it from the vehicle. Store in a cool, dry place and periodically check its voltage, recargándola si cae por debajo de 12.6 voltios.
