Motorcycle Battery Maintenance and Charging System

You’ve seen it before, a lone motorcyclist on the side of the road. It could just be a quick rest break- or a dead battery. No matter how well you maintain your motorcycle battery, you could one day find yourself in need of a jump.

Knowing how to properly jump-start your bike can get you quickly and safely back on your way. And if you are planning to change your bike’s battery then first you need to check the motorcycle owner’s manual for its proper size and minimum recommended cranking amps. Always use recommended motorcycle batteries because it improves starting and provide longer life.

Basic Guide of Jump-Starting

  • Make sure you have the right gear before you ride. Having a cell phone and some water with you is common sense, but if you want to get that bike started again, what you’ve absolutely got to have is jumper cables.
  • In this case, opposites do not attract. If you’ve got a 12-volt battery, you want to jump it from a 12-volt battery. If you have to jump your motorcycle battery from a car battery, then just remember to take the keys out of the car. Never turn on the car’s engine while it’s hooked up to your bike. Car batteries have enough juice to start yours up without the engine running, and if that car engine turns over with your battery attached, it could easily fry your motorcycle’s entire electrical system.
  • Your motorcycle and the jumper bike should be close but never touching. Contact between metal could create electrical common ground and ignite the gasoline in both tanks.
  • Turn off any lights or other unnecessary functions, including radios or music players, since any voltage surges could end up damaging or erasing memory circuits.
  • Making sure that both engines are off, connect the motorcycle batteries in parallel, positive to positive (RED clamps), negative to negative (BLACK clamps). When making connections, be careful not to touch the clamps to each other or to anything other than the appropriate connection points. Start with the discharged battery, making the positive connection first, then connecting to the positive (+) terminal of the good battery.
  • Next, connect to the negative (-) terminal of the good battery first, but rather than connecting the last clamp to the negative terminal on the discharged battery, attach it to an engine bolt or fame ground away from it and its vent tube. This minimizes the risk of explosion. Chromed or painted parts should be avoided. Apply the same procedure to car batteries.
  • (Once you’ve got your motorcycle started, disconnect in the reverse order of the connection sequence.
  • (Drive your motorcycle directly to someplace where you can test and charge your motorcycle battery because chances are once you turn it off, it won’t start again without a jump or re-charge.

Charging is Important!

Motorcycle batteries don’t work exactly like car batteries. Letting your bike idle, or riding for 20 miles isn’t going to re-charge it. To do that, the engine rpm has to reach what’s called the ‘break-even rpm point,’ and maintain it long enough to make up for energy losses from starting and self-discharge. Battery testing and complete charging is the only real way to avoid another dead battery situation.

When you charge deep cycle batteries, the water inside breaks down into hydrogen and oxygen, leaving dangerously combustible gases inside it and around the vent holes and hose. If these ignite, your motorcycle battery can explode, spraying battery acid in all directions. This is not an urban legend- it does happen.

That’s why it’s so important to take the utmost care when jump-starting, and not to endanger yourself further by smoking or creating sparks near the battery. It’s a great idea to keep your full helmet or face shield on, or at the very least, some goggles.

Remember, when it comes to motorcycle safety, it’s all about equipment. Having the right gear, like jumper cables or safety goggles, is so vital that it’s ridiculous to call these things “accessories.” To make sure you’re safe on the road, Impact Battery carries a large range of accessories and advice on how to use them. Stay safe, and we’ll see you on the road. has complete information about motorcycle and other batteries. You will know how safely you can jump-start your motorcycle and other vehicles.
