Q I have always carried jump leads and have used them on a few occasions to help others and on my own Ford Focus after flattening the battery. I now have a Suzuki Vitara bought new a year ago and I'm looking to buy a booster pack as you recommended in the June 2018 issue. The Sealey RS13 12HV costs £96, but the more modern Sealey SL1S is £240. Which would you recommend? Mark Pash
A The Sealey RS13 12HV is a good jump pack and, if kept charged, will serve as a good stand-by unit for your Vitara. However, the Sealey SL1S is more versatile and can also be used via a USB lead to charge devices such as mobile phones, tablets, etc. It also has the advantages of a lithium-ion battery, which holds its charge for about five times longer. Plus it's a physically smaller unit, so it can be stored in a vehicle more easily.
At present, the cost of the SL1S is £239.94. The alternative is, of course, roadside assistance and, at the moment, the AA are offering a year’s cover for £39.
