Guys, i have a suspission that my near new 12 volt car battery is running down in volts due to something electrical. if the vehicle is left for a few days the battery does need a charge up for starting of the engine. i had an alarm fitted which i now have disconnected thinking it could have been draining current whilst sitting but just today i did charge the battery up to approx 12.80 volts and every hour i checked the voltage with a multimeter and noticed a drop of around .10 per hour, the voltage at present is 12.44. i also did disconnect the terminals and checked voltage drops per 1/2 hour and there was a slight drop per test. i took the battery back to place of purchase and they checked it with some fancy unit and the read oput said; needs a charge up. i mentioned to them it has only just been charged and its loosing a slight percent per every hour , they will charge this up overnight and test it tomorrow so we will see what happens but as mentioned i still have a feeling something else is draining the battery, any ideas ?
