There's a strong case for a dedicated motorcycle battery charger. Most batteries will become discharged if the bike is left alone for a period of time (sometimes as little as a couple of weeks) and this is particularly true for bikes that have trackers fitted, as these inevitably draw power from the battery to offer their protection. So although only a small amount of current is drawn, it's inevitable that an unattended bike will have a flat battery before long.

This can be annoying at best and scrap the battery at worst. It is annoying because you come to the garage for your first ride in some time and the battery is dead. If you’re lucky, you can jump-start it and go for a run – hopefully the charge you get back into the battery will see you through your ride.

However, in the worst-case scenario, the cells in the battery can become damaged to the point where they simply cannot hold a charge and the only solution here is to replace it. And while motorcycle batteries generally are less expensive than car batteries, for example, it’s still an expense you could do without.

How to avoid flat batteries on your motorcycle

The solution, of course, is to leave your bike with its battery on charge when it’s not being used. This is particularly true for bikes that are laid-up for winter and in this case, a battery optimiser/maintainer can be useful, as it not only charges the battery but it carries out a series of conditioning cycles. These put some load on the battery so that it isn’t simply under constant charge, as this can also, paradoxically, damage the battery and reduce its capacity as well.

One point you should consider is what kind of battery your motorcycle uses. Lithium batteries are becoming more popular as they can offer better performance than traditional lead-acid ones. However, they require very different charging characteristics and as such, you should be careful not to pair the wrong charger with the battery, as this can have a negative effect on the battery and can even be dangerous.
