Its almost that time of year where we start winterizing our motorcycles and take the battery out of the bike for the season. However removing the battery isn’t enough to ensure a long battery life. If you want your motorcycle to have less trouble starting next year, you’ll want a battery maintainer.

Benefits of a Battery Maintainer

There are many benefits to owning and using a battery maintainer. Maintainers not only keep your battery charged but they can also do this without risking overcharging and damaging the battery. Some maintainers can also be used for car batteries. In addition battery tenders can also help revive dead batteries and give them longer life.

Types of Battery Chargers

There are actually several different types of battery chargers, and understanding the differences will help you select the right one for your motorcycle.

  • Standard Charger: A standard charger works the same way as your typical phone charger. You plug in and your battery charges until its at 100%. The problem with this type of charger is that leaving your battery plugged in and “charging” when its at 100% can lead to damage the battery, waste electricity, and it could even be a fire hazard.
  • Trickle Charger:  The trickle charger is a step up over the standard charger. This type of charger monitors the battery’s charge level and adapt to the battery’s needs. These chargers also stop when the battery reaches 100% charge level. This eliminates the risk of overcharging and reduces electricity usage and fire hazard potential. The big benefit is that this battery is “plug and forget”. Your battery will be at 100% charge and ready to go.  
  • Floating Charger: A float charger is a battery charger and maintainer all in one. It works by charging the battery to 100% and then shutting off. The battery will then drain to a pre-determined level before the float charger turns back on again. This process will repeat for as long as you have it plugged in. The upside is you save energy, reduce the risk of damaging the battery, and reduce fire hazards from overcharging. The downside is that the battery might not be fully charged when you remove to reinstall in your bike.

Key Features

There are several other factors for consideration when selecting a charger. The amps and voltage is crucial to selecting the right charger. A 12V battery will need a charger rated for said battery. The amount of amps will determine how fast the battery charges. Generally the fewer amps the slower the charge rate which is good for battery life, but if you need to charge in a hurry, having a high amperage charging would help.

Like charging your phone, charging a motorcycle battery will produce heat. A battery that gets too hot will get damaged. Having a battery charger that monitors battery temperature could just save you your battery.
