A heavy duty jump starter is, as the name implies, a unit for applications requiring a large amount of cranking current and with a high peak current available. This can be for ordinary car batteries which are really deeply corroded and have been sitting for a long time, or for very high capacity batteries, such as those on trucks and large SUVs, which need very high current to quickly revive them to a point where the vehicle can actually be started. Another function of a heavy duty jump starter is for applications where a number of consecutive jumps are required, as in professional environments such as in dealerships, service centers, road side assistance, and so on. They are also therefore perfect for the outdoor enthusiast who would like to be prepared in the event several of their buddies need a jump start as well during a particularly grueling expedition!
The Jump ’n Carry JNC660 is certainly a top notch, heavy duty class jump starter, from a name which has become synonymous with unbeatable quality and ultimate reliability in the portable jump starter market. It is fitted with a 22Ah maintenance-free, lead acid battery, providing the capacity to start many, many vehicles on a single charge. It is difficult to put an exact number on this because it really depends on the state of the batteries that are being started, but you can be rest assured that the JNC has plenty of juice for pretty much any 12V battery jump starting requirements! The JNC105 PROFORMER battery in the JNC660 is also renowned for its incredibly durability, and will unquestionably survive hundreds of charging cycles, guaranteeing a long life for the unit.
