When you need a little boost, reach for a jump battery and get your motor running.

A motorbike being charged by a jump pack

Somedays, you need a little help to get going, and that can also be true of your bike. For a number of reasons, your battery may be a little low on energy when you want or need it and you don’t have time to plug your charger in to get it back up to full strength before you have to head out on the daily commute. So what do you do? At times like these, you need a jump battery.

We’ve all, at some point, jump-started someone else from a running motorcycle or car. And using a jump pack is effectively the same but instead of using another vehicle, you use a standalone battery designed specifically for the task.

Versions for cars tend to use quite large batteries but motorcycle jump batteries are much smaller because generally, bike engines don’t need so much power to turn them over ready to start.

There could be a variety of reasons a motorcycle battery is low on energy; if it is fitted with a tracker by the manufacturer – or an aftermarket one to help prevent theft – then this can drain the battery over time.

If the battery is not quite at its peak and there’s a cold snap, this can also deplete a battery – the electrical supply is based on a chemical process and a drop in temperature results in a slower reaction and hence, less power.

Of course, in either of these situations, the ideal scenario is the bike is left connected to a charger or conditioner as we looked at in the past but sometimes, you just need that quick hit to get you going.

Although this jump pack from Noco claims to be able to start car engines up to 4.0-litres, weu2019d reckon it is more useful for motorcycle engines. The material doesnu2019t specify what size the actual battery is but it claims cranking current of up to 500 Amps from an internal lithium battery.

It charges by USB and includes a USB output as well, for charging phones or other devices and also includes an LED lamp. It has an override function to bypass detection circuits if the main battery is so flat it can’t be recognised by the jump pack.

At the pricier end of the scale, this example from Autowit uses a supercapacitor rather than an internal battery to provide starting power. What that means is that it doesnu2019t require traditional long-term pre-use charging but will require to be u2018energisedu2019 from the vehicle with the flat battery or a separate power source then discharges its stored energy quickly, offering the necessary power to jump start the flat vehicle.

This jump pack from Sealey is definitely not cheap but it packs a hefty punch u2013 up to a whopping 1600Amps of current for cranking.
