Why Should You Trickle Charge A Motorcycle Battery?

How Do You Trickle Charge A Motorcycle Battery?

Now you know why you should trickle charge your motorcycle battery, the next step is learning how to do it! Fortunately, if you’ve charged a battery before, you’ll soon realize it’s just as easy! And if you haven’t, here are the steps you should take!

Inspect Your Battery

First of all, you should inspect the battery for any problems it may have. Cracks, leaking areas, bulges, and corrosion are all signs that you may need to replace your battery (although in the case of corrosion, it can be fixed.)

If you notice that the battery is damaged (apart from corrosion), then you should avoid charging it; however, if the battery is fine, you can move on to step 2.

Find A Location To Charge The Battery

Before anything, you need to make sure that you’ve found a suitable location to charge your battery. It needs to be somewhere well-ventilated, where heat isn’t going to damage anything. When you’re charging a battery, it’s going to give off a lot of heat as well as noxious fumes, so doing this is vital.

Adjust Your Trickle Charger

The next step is to adjust your trickle charger so that it powers your battery with the right amperage and voltage. To do this, look for the charging specifications on the battery itself. It’s important to do this, as different batteries are going to have different charging recommendations.

Remove The Battery

Now that the trickle charger has been set, the next step is to remove the battery so you can begin charging it. In most cases, leaving the battery in will be fine; however, if there is an electrical surge, it could end up damaging the battery. And because the battery is so easy to remove, it’s normally the best choice.

Remember to disconnect the negative terminal on the battery first, followed by the positive terminal.

Make Sure Your Battery Has Been Grounded

Before you begin charging the battery, you need to make sure that it has been grounded first. You can ground the battery by attaching the charger to something with enough metal to allow any excess electricity to dissipate. The vehicle chassis, grounding rod, or engine block are all great choices for this!

Begin Charging

Now that everything is ready, you can begin charging your motorcycle’s battery! If the charger is turned off, the order in which you attach the cables shouldn’t matter. However, if the power is on, you should connect the positive cable first before attaching the negative cable.

Keep An Eye On It

Now all you need to do is check on the charger and motorcycle battery every so often to make sure that everything is still working correctly. When you know everything is working correctly, you can leave it again until it’s fully charged.

Place The Battery Back

The last step is to obviously place the battery back where you found it. To do this, make sure that you’re disconnecting the negative cable first and then the positive from the charger. Then place your battery back into the motorcycle, and connect the positive cable first, then the negative cable, and you’re good to go again!

How Often Should You Trickle Charge A Motorcycle Battery?

Can You Trickle Charge A Motorcycle By Letting It Idle?
