To ensure the stability of the connection, it’s essential to have a tender, compatible with the battery’s power capacity. This prevents charge leaks and wearing-off.
Of course, if you happen to find a versatile 6V/12V charger, it should do. Since such appliances are very adaptable to different kinds of batteries, they can do well with your motor vehicle. However, make sure that the recommended voltage and wattage comply with those of your battery.
How Do You Use a Motorcycle Battery Tender?
A motorcycle battery tender works like any other charging device. You have to supply a sufficient power output for the appliance through an outlet, for instance. Connect them using a cord provided by the charger’s manufacturer. It’s important to use only the original accessories since they can vary in power capacity so that you don’t damage your utilities.
When your battery is connected, choose the right mode (if there are any). Normally, you would have to select the 12V charging option. Watch the display for information regarding the charging process since there can be indications of failure or other issues. After the display lights solid green, remove the charger since the battery is ready to go.
What Size of a Battery Tender Should I Buy?
The most important thing about choosing a trickle charger is, of course, the compatibility with your battery. When it comes to picking the size of a product, it’s completely up to you since it doesn’t matter here. Fortunately, there is a whole array to choose from.
The optimal size for a charger would be around 6-8 inches in length. This way, the appliance is compact enough to carry and keep in the glove box. However, there are also bigger options if you don’t mind the size. Choose a 10-12-inch charger to use in your garage since it can also be a fit for other vehicles.
Can You Overcharge Your Harley Battery With a Trickle Charger?
Well, overcharging any battery can cause lots of aftermaths, like reduced performance, wear-off of the circuits, etc. But most modern chargers are designed to shut down automatically when a battery has reached its full charge.
