Selecting the correct charge rate setting for your battery

When using the OC-2412U it is important to select the correct charge rate for the battery you are charging. A common mistake many people make is to select the highest charge rate setting, not realising it may damage the internal components, reducing the battery life. The recommended charging Amps for a flooded lead acid battery is roughly 10% of its Ah rating. For an Absorbed Glass Mat (AGM) or Gel battery this can be increase to 20% of its Ah rating.

If you are unsure of the Ah rating of your battery please check the specifications on the battery or contact your battery's manufacturer

The 2A - maintenance mode - will charge a range of lead acid batteries between 6 and 40Ah and will maintain batteries up to 200Ah.

The 8A - silent charge mode - will charge a range of lead acid batteries between 24Ah and 160Ah and will maintain batteries up to 240Ah. 

The 12A - rapid charge mode - will charge a range of lead acid batteries between 36Ah and 240Ah and will maintain batteries up to 360Ah. During this mode, the internal fan may engage from time to time if the charger gets hot.

  • Battery Charging vs. Battery Maintenance

    What's the difference between the two and which battery charger suit your requirements best? Firstly you need to determine whether you need to recharge a flat battery entirely or just keep a battery at full charge.

    Battery charging is when you are requiring to recharge a flat or dead battery to full. Battery maintenance on the other hand is when you just want to keep a battery topped up. For instance, if you're storing a classic car that you only drive a few times a month but want to ensure it's ready to go on a sunny afternoon you would require battery maintenance as opposed to battery charging. This is often referred to as trickle charging a battery. All OzCharge battery chargers perform both functions, and understanding each charger's limits is important.
