![]() ![]() Some are just mobile phone charging batteries which only operate at 5v so make sure yours is capable of running at 12v It sounds silly but not all the devices sold as jump starters are 12v. What to look for in a portable motorcycle jump starter If you’re going to carry jump leads you might as well carry the powerbank as it’s the same size and weight and can do so much more. You press your bike’s starter button and boom, it’ll spring in to life! In ConclusionĪs you can see, a portable motorcycle jump-starter is a great option. On a lot of these portable jumpstarters the lights flash which indicates you have a time-limited window (usually 5-10 seconds) where the powerpack is ready to dump its power. You connect up the powerbank and press the button to get it to prime itself. Sometimes when bump starting a bike by hand you can fire the engine up but the systems haven’t booted up in the order they want to, and so you might get a warning light. They’re really good because they prime your bike’s systems before you go to start the engine, so the bike will start just as it should. ![]() They’re small in size but they use a lithium battery similar to that used in a mobile phone, so you have the equivalent of 20 mobile phone batteries in your hand. Use a portable jump starterĪ portable jump starter will fire up your bike, even if the battery is kaput. This is unlikely to happen as the bike will only draw what it needs from the car battery. Some people worry that jump-starting a motorcycle from a car will damage the bike’s electrics. A car battery has a far larger capacity than a bike battery and so starting your bike won’t drain the car battery. However a good rule of thumb is that if the car has an engine that is double the size of your bike’s engine, you don’t need to have the car’s engine running when you go to start your bike. This is an almost identical approach to bump-starting your motorbike from another bike. ![]() If the bike won’t start again, you might have a battery issue or more likely the bike’s charging system, the regulator/rectifier might be dead. Let your bike run for 5 minutes at tickover to charge the battery. Once your bike is running you can disconnect the leads (negative first). Then switch on your ignition and fire up your bike. Then get your mate to pick up the revs on their bike, 2-3,000 rpm ought to do it. Start up your mate’s bike and let it run for a minute. Then connect the red (positive) terminal to your mate’s red terminal. Connect your black (negative) terminal to your mate’s bike’s negative terminal. You need a set of jump leads for this one. These can be used to rekindle a dead battery but shouldn’t be left on for longer than a minute or you can overcharge the battery, causing it to fail. Workshop grade chargers will have a BOOST button (or similar) that increases the amps the charger forces into your battery. ![]() This isn’t the best thing for the charger to be doing but using it in this way once or twice should be fine. However if you don’t have time, plug the charger in, let it charge for 1 minute and then try and start the bike with the charger connected. If your motorcycle battery charger has a car mode, this will use a higher amp output so keep it on this for 5 minutes. If you are at home and you have access to a battery charger, if you have time, you can just plug the battery charger in for 40 minutes to boost the battery. Don’t try this on loose surfaces or wet surfaces as the rear wheel won’t grip.When you dump the clutch time it with dropping your bum onto the seat to help the rear wheel grip.While it sounds sensible to push your bike (as there’s one less thing for you to have to go), you’ll have a a lot more drag on the drive system so neutral is best to build up speed.Gravity helps, so if you are on a gentle slope use it to your advantage!.If you are in full bike gear you will end up getting hot and pretty frustrated.Top tips when bump-starting your motorcycle: Once you get the technique it’s actually easier to push the bike yourself and hop on. You can have the bike in neutral, build up speed, jump on and quickly select 1st gear and drop the clutch. You can either run alongside the bike or have someone push you. This involves pushing the bike with the ignition on and dropping the clutch to engage the drive from the rear wheel to turn over the bike. However it is a very reliable and simple way to get you out of trouble.
