You don’t usually think of car batteries as expendables, but it looks like that is changing. An interesting article in this weeks Wall Street Journal talks about how the demands of today’s electronic-laden cars are taking a real toll on their batteries. A car battery has traditionally lasted 3-5 years but the addition of power sapping devices like DVD players, GPS systems, heated cup holders and security systems has radically altered the life of these batteries.
The design of the auto battery is little changed in decades and what we ask these batteries to do was never imagined 10 years ago. It used to be that about the only thing that used power when the car was shut off was the clock. Now all sorts of items from the cooling fan to your cell phone charger continue to use power long after the car has been parked.
Experts in battery maintenance recommend that the battery be disconnected when the vehicle is parked for more than a couple of weeks. Better yet, use a device called a “trickle charger” to keep the battery charged up even when the car is not being used. These same experts warn that the biggest threats to battery life, extreme weather and harsh vibtration,can’t be avoided.
With the cost of a replacement battery sometimes exceeding $200.oo a little thought given to battery mainteance can go a long way.
