Ideal for easily starting petrol engines up to 6 litres and diesels up to 4 litres this unit has 1500amp peak power output and the 1m leads are operated by a heavy duty isolator switch, so you can safely connect them to the battery. In that regard, these products are much like Tablets and Smartphones, where if you want to replace the internal battery, you will need to either source the battery and do the job yourself, or take it to a professional, which, with the price of the new battery added to the labour for fitting, will most probably cost you more money than if you were to just buy a newer model.

Thankfully, the Clarke 4000 does not fall into this category. Once you get to the point where the internal battery is starting to get weaker you can just buy a replacement. Fitting is fairly straight forward. But be warned, they are not cheap. However, for what they cost, and considering the amount of power you get from the Clarke 4000, the price comparison to other models would be a good quality, but much smaller in size and power 600A - 800A (15000mAh - 18000mAh) unit. Fortunately modern lithium battery-based jump starters are compact and lightweight, and can even double up as an everyday USB charger in some cases. But traditional big heavy lead/acid starters remain popular too. In this test we compare both types, and a third emerging technology.

Anything over the maximum engine sizes and it will more than likely fail to start the car. And usually with jump starters, its wise to shave a litre off each end of what the manufacturer claims it will start. But, in saying that, there are quite a few people who have reported using the Clarke 4000 on petrol engines well within the 4.5 litre to 5.5 litre range with close to a 100% success rate. That also goes for diesel engines within the 2.8L - 3.5L range, too. Heavy-duty battery designed to jump start larger engines, including petrol engines up to 6L and diesel engines up to 4L This can lead to a strange case of permanent cell damage from the long period of dormancy that can see the unit totally refuse to accept a charge. To prevent the issue of irreversible dormancy make sure you give the unit a charge every few months. We prefer models with built-in safety features and alerts, to warn against wrongful connection, dead shorts, and a low charge on the car battery, when being used as a jump starter. Such alerts may just save you damaging your jump starter and your car’s delicate electronics. The Clarke 4000 Jump Start boasts a maximum turn-over capability of being able to safely start up to a 6 litre petrol and 4 litre diesel. Because its known for high power, there is a little bit of confusion with potential buyers as to whether its compatible and safe to use on smaller engines. The answer is yes, it can safely be used to start engines of all sizes lower than the stated maximums.So really, it makes sense to buy the replacement battery, that is, if you have been happy with the Clarke 4000 and have had considerable usage from it before needing to replace the battery. The Clarke Jumpstart 4000 battery starter is suitable for use with a range of petrol engines up to six-litres as well as diesel engines up to four-litres. This high-capacity battery is practical and powerful, with an ergonomic design that allows for easy transportation and storage. It is also supplied with extra-strong one-metre leads with battery clamps, as well as an integral worklight and on-board storage.
