If you wish to store your motorcycle for a longer period of time you need motorcycle battery tenders. A battery tender is an essential device that plugs into a standard AC wall outlet and transfers power to the motorcycle’s battery (12V or 6V) via amperage to keep it charged.
Motorcycle battery tenders do not get weak from use. However, batteries do. On average, a motorcycle battery should last for 48 months. Lack of maintenance on the other hand could cause the battery to go bad faster.
Battery tenders help extend life of your battery all year long. A good battery tender has an inbuilt smart technology that detects when the battery is fully charged and shuts down automatically.
What do battery tenders do?
Battery tenders play a big part in ensuring batteries remain operational over long periods of motorcycle inactivity. They are designed to fully charge the battery and maintain them at recommended storage voltage. This also protects the battery from potential damage caused by trickle chargers.
Battery tender chargers therefore are valuable to anyone living in long, cold winters or to a person who leaves their motorcycle unattended for two weeks or longer.
Characteristics of battery tender battery chargers
They are fully automatic: Battery tenders are designed to automatically switch off immediately a regular charge cycle is attained. The switching off eliminates the need to keep checking on the condition of the battery.
Full output power at low AC Line conditions: Except for the tenders with an output current of 2 amps or less, battery tenders deliver full output power with input AC line voltage as low as 90 VAC.
Zero to minimal current draw from batteries: Most battery tenders will draw zero current from the battery when AAC power is disconnected.
Battery tender chargers offer some of the highest charging power density
Visual indication of charge progress: Battery tenders are fitted with colored lights which indicate the charging progress.
Battery maintainer versus battery tender
Battery maintainer and battery tender perform the same task of bringing your motorcycle to full charge and maintaining it at recommended levels. However, they should not be confused with standard battery chargers.
Ordinary battery chargers simply send a constant charge to your motorcycle battery regardless of whether the battery needs to continue charging or not. A battery tender is able to perform many more duties that a standard charger cannot perform. Battery tender helps prevent the motorcycle battery from overcharging and hence protecting it from potential damage. Battery tenders also have the ability to monitor the rate at which a battery charges and this helps prevent damage caused through fast charge rates.
How to buy the best battery maintainer for your motorcycle battery
Choosing the right battery tender for your motorcycle battery can be a tough task given the many options we have in the market. The following factors will therefore help you make the best choice:
Charging modes
If a standard charger came with multiple charging modes, probably you wouldn’t see the need for battery tenders. The ideal battery tender should therefore come with trickle charge mode that would help reduce amount of power supplied to your motorcycle battery once it is fully charged.
The device should also be able to shut down charging for some time and be able to maintain its optimal levels through the winter season.
Compatibility
The kind of compatibility to look for should be in terms of amperage and voltage. The voltage of the device you purchase should match that of your motorcycle battery. For instance, a 6 volts battery tender will work with a 6Volts battery and 12 volts battery tender with 12 volts battery. If you are looking for flexibility therefore, consider models that work with both 6 Volts and 12 Volts batteries.
On the other hand, ensure that the charger’s amperage rating matches the amount of power your motorcycle battery needs to be supplied with.
Ease of use
You’ll definitely love a battery tender that is quite easy to connect to your battery. The main focus therefore should be on how the battery tender is designed to connect to your battery terminals. Consider also a tender that comes with a cord, long enough to make it easy to use with your battery.
Safety features
When charging your battery, safety is paramount. Look for a battery tender that comes with safety features. Consider battery tender models with spark-proof connectors, reverse polarity protection, short circuit protection and overcharging protection.
To help ensure that you are using the right charge settings for your specific battery, consider a device with automatic voltage detection feature.
Versatility
Consider a battery tender that works with different types of batteries. This can be helpful especially if you also own a car, a tractor, watercraft or a boat.
LCD/Indicators
Indicator lights help you know the charging status of your battery. There are models which come with LCD screens that will give you more than just charge status information.
Connectors
Availability of connectors is a point to consider when looking to purchase a motorcycle battery maintainer. If the battery charger is not compatible with the motorcycle battery, it might be difficult to attain excellent services. Be keen on how the maintainer clips onto your battery, especially when there are different types of terminals. Some battery maintainers come with shorter connection cords and in this case you may have to deal with issues such as availability of outlet options.
