We all know too well the feeling of dread in the pit of your stomach when you turn the key in your Renault's ignition, and nothing happens. Overuse is the main cause of battery failure, and so that innocent few hours of listening to the radio while your wife is in the shops, or the couple of times you forgot to turn off the lights when leaving the car in the garage can all take their toll on you car's battery. Excessive heat is also a major culprit and can affect even those living in cooler climates, since long drives cause the engine to heat up, and possibly reduce the life of your battery even further.
The battery is so vital that not only the engine, but the radio, lights and heating are unable to function without it. So how can you be confident in this key component of your Renault? Batteries have a rough life expectancy, and although this is considerably variable, it lies somewhere in the region of 2-3 years for a cheaper battery, and 5-6 years for a more expensive battery. Although it may cost a little more, a higher end battery has a higher cycle count (the number of times you can fully charge and discharge the battery over its lifetime), and so will give you the peace of mind that no matter what the weather is doing outside, you will be safe inside your car; driving the kids to school, or driving to work on those cold winters mornings safe in the warmth of your car, with your headlights lighting the way before you, and your radio to keep your journey a pleasant one. So remember to keep an eye on your battery, and replace every 2-3 years, or at the first sign of your battery's capacity starting to decrease.
