    New battery, black spot?

    I recently changed my battery to a bigger 70Ah GM one, only about a month ago. Yesterday I was tinkering under the bonnet and already the green spot has turned black. How may this have happened so soon?

    Cheers

    Depends on how many miles/length of your daily drive and how often you start the car and whether its used? At this time of year the battery gets a hard time so it takes time to recharge it from all the starting and/or just sitting there powering the alarm. The one fitted to my Omega is often black (not used much) but it works fine I just charge it every few months.

    If you use your car daily and do reasonable mileage try checking your boot/glove box lights?

    As Techno says, lots of short trips at this time of year are hard on a battery. It doesn't always get a long enough run to recharge up what the starting of the engine has taken out of it.

    As Measorpaul said the indicator is a waste of time and go faulty on a regular basis,as said do a test on the battery HTH
