We stock a range of different battery booster packs in various voltages and brands here at Toolforce.

They’re an absolute must-have if your vehicle is the subject of a roadside breakdown.

Check out our full range of battery booster packs in our vehicle roadside breakdown category.

Battery booster packs, or charge packs, deliver a charge to a flat or low vehicle battery, typically designed for use in an emergency to help start a vehicle’s engine. 

Vehicle jump starters are also a useful tool to have in a car dealership or yard where vehicles may be sitting idle for months at a time.

However, it’s not a case of one size fits all. You must pick the best battery jump starter to suit your needs.

What type of Battery Booster Pack do you need?

Normal charge packs will typically work on batteries ranging from 6 to 12 volts while industrial-grade ones designed to jump-start medium and large trucks can go up to 24v.

Don’t forget that jump starters can be used for virtually any vehicle with a battery, from cars and trucks to motorbikes, lawnmowers and watercraft.

Smaller vehicles like motorcycles sport 6v batteries while the vast majority of cars and vans run on 12-volt batteries.

The material of the battery pack might be another consideration to take into account. Typical Lead-Acid battery packs are cheaper, but Lithium battery packs on the other hand are more portable, discharge more slowly and retain their charge better.

Car Booster Pack

Car batteries won’t need as much juice as batteries in larger vehicles to jump-start when they break down.

You won’t generally need anything bigger than a 12v booster pack to jump-start a car, pickup or SUV.

We have a wide range of these in stock to get you out of trouble in a roadside breakdown.

Here are a few examples from Three of our trusted brands, Lemania, Draper and Sealey.

This unit can also supply several full charges for smartphones and MP3 players or one full charge for your tablet/laptop via two USB outlets (5V/2.4A and QC 3.0).

Truck Booster Pack

Trucks require a more powerful jump starter when they break down because their batteries are bigger. The size of the machinery these truck starters are trying to start is more demanding.

In cases with a truck or larger machinery, you should look for a truck booster pack with at least a 24V capacity.

How to jump-start your car using a battery booster pack

Using a battery jumper couldn’t be simpler – but you ought to double-check where everything goes before you go ahead and hook it up.

Here’s a handy guide to remind you how to use a power pack.

1. Check the battery booster pack

Make sure the jump starter pack is fully charged

Put the pack somewhere stable, where it won’t fall over. Putting it on the engine is a bad idea – it might fall off when the engine starts.

2. Connect the red positive (+) jump lead

Connect the red positive (+) jump lead from the battery pack to the positive (+) terminal of the car battery.

3. Connect the black negative (-) jump lead

Connect the black negative (-) jump lead to an earthing point on your car. Unpainted metal on the engine block or chassis is best.

4. Switch on the pack

Once the battery pack is connected, switch on the pack.

5. Try to start the car

Try to start your car by turning the key in the ignition.

If it doesn’t start, keep trying. If it still won’t start after a few tries, there’s probably a more serious problem that needs professional help.

6. Let the engine run

If the car starts, keep the engine running for about 5 minutes.

After 5 minutes, switch off the booster pack and allow the engine to run for a further 5 to 10 minutes.

7. Turn off and disconnect

Now, turn off the engine.

Once you’ve done that, remove the jump leads in the reverse order of how you put them on (first disconnect the black lead, then the red lead).

8. Restart your car

Try turning the keys in the ignition to see if the car starts up again.
