Car & truck starting batteries go flat when left for long periods of time. This process is called
'natural
discharge'. In most vehicles it will occur at about 10 to 25% per month - high temperatures
accelerate the process.
A flat battery can often incur long-term damage as lead acid batteries don't like being left in a
discharged state, and so the battery often needs replacing.
Small solar pv panels can be used to keep the vehicle battery 'topped up'. For most cars, wattages of
around the 5w region seem to work well in the UK. Trucks have larger batteries and therefore are
likely to need a 10w panel.
Our range of flexible solar battery chargers have been very popular in this application, as they have
no sharp edges and take up virtually no room in the vehicle.
With the increase in 'high power' vehicle alarm and tracking systems - many performance, collectors
or low mileage vehicles have even more of a struggle to keep up with the drain on the battery. Some
car owners have solved the problem using a 10w solar panel.
