Car Battery Keeps Going Flat? - Try a Solar Charger
When does your car battery go flat?
Right when you don't need it to.
A flat car battery is one of the most frustrating things to deal with. If you are in the city you always hope for a good samaritan to give you a jump start. Outside the city, you are probably on your own.
A flat battery is more likely to occur in vehicles used infrequently. Car, boat, tractor. If it relies on a battery, the risk is there.
Why did the battery go flat?
All batteries gradually lose their charge over time when idle. The rate of loss increases as the ambient temperature increases.
Without frequent recharging, a battery can quickly fall to the level where it will no longer function. If it continues to lose its charge it can suffer permanent damage as a chemical reaction known as Sulphation occurs.
This poses a real problem for those infrequently usung their car or boat.
The Car and Boat Battery Solution
A Solar Charger can continually top up your battery without requiring you to be present. Once the unit is set up there are no ongoing costs and no more frustrating wasted days.
One of the common questions asked of solar chargers is "Won't it overcharge the battery if it is continually charging?"
This is not the case for any charger rated at less than 10 Watts when used on a typical car battery. They prevent the loss of charge and keep the battery topped up without going too far.
Chargers are now much more convenient to use with most models plugging into the car's cigarette lighter while still offering the option of direct battery terminal connection.
As solar technology becomes more commonplace, the price of charging units has come down. For around $50 or less you can get a "set and forget" charger to make sure your vehicle is ready to go whenever you are.
