New data from RAC reveals your car battery is most likely to hit the snooze button on a Monday, with roadside patrols attending over 150 call outs for flats, on average, every Monday last year.

RAC General Manager Motoring John Griffiths said last year, 7,811 battery related call outs were received on Mondays with the chances of a flat decreasing as the week progressed.

“The high rate of Monday battery call outs could be attributed to cars being left unlocked or doors left a-jar over the weekend which can drain a modern car battery,” Mr Griffiths said.

“Other factors could include leaving lights on, old age, extreme temperatures and service history.

“Often, an old battery will become sluggish before it dies so when this happens it’s important to have your battery checked by a professional to avoid a breakdown situation.

“Batteries like to be kept fully charged so leaving your car stationary for long periods can also cause a battery to fail,” Mr Griffiths said.

“Some motorists may opt to disconnect their battery before going away, but it’s important to know what’s right for your particular car and remember that in more modern vehicles this can cause electric system failure.

“Our advice is to use a battery charger to keep your battery fully charged while you’re gone.

“Even when you’re home, regular use of a battery charger can help keep your battery maintained. It’s also important look out for any build-up, cracking or leaks.”
