So over the past few months I have been getting the brake warning on start up and as we all know it suggests battery is on the way out so checked it and sure enough its only getting up to roughly 75% charged
anyway I went and picked up a new bosch battery today from euro car parts got home and the first thing I did was check the charge state!
to my horror its showing 10.6 volts!!!
Am I right in thinking batteries should come already charged and must be kept charged and if the voltage drops below 12.3 then it needs to be charged otherwise permanent damage can be caused and the life expectancy reduced?
I have searched online and found nothing about if they should be supplied fully charged etc
Any advice welcome
