I probably already know the answer but having just spent money on this car I'm reluctant to fork out again, it's starting to become a bit of a habbit.
It's just been in the garage for new bottom pulley and some work on the brakes.
When I got the car back the clock was flashing... thought nothng of it.
used it for a couple of short trips and battery dead - jump started ok - charged battery for about 3-4 hours.
Used car yesterday about 70 miles stop/start about half a dozen times.
Went to use it today, just about turns over not enough to start.. charged for an hour and started.
Testing it I get around 12.5 v. (slightly higher when it's just finished charging)
Battery drain test with car shut down I get around 0.001a or 0.1 ma. Rising to around 1a when you open the door and put internal lights on.
Voltage test with engine running I get around 14.3 rising to 14.6 when you throttle the engine.
Had the car nearly 5 years and I have not fitted a battery - and wait for it it's a Tudor battery which from reading on here don't get too good a write up..
Time for new battery ???
