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.
