Many of us are using our cars less these days but are relying on the battery to power devices which keep running even when the car is switched off, such as alarms, trackers and dash cams with parking modes. Even a clock could drain enough power over time to mean you hear the dreaded click when you try to start the engine.
In an ideal world we’d all keep our cars topped up using a mains-powered battery charger, but in reality not all of us have access to a plug.
The solution could be to use the sun to keep your battery in tip-top condition with a solar-powered charger. Place one in the windscreen and it could ensure you always have enough juice to keep your gadgets running and still churn the starter motor when you turn the key.
