In April 2019 I replaced the original Banner battery, it was 5 years old, so a reasonable life.
The new battery was a YUSA HSB075, from Halfords, with a 5 year guarantee.
In October it was going flat regularly, alternator charging properly, so Halfords replaced it, under warranty.
Now, a year later, it is holding charge for no more than a week, today after 8 days in the garage it is showing 6.2v, so on charge again.
Back to Halfords, but I'm getting a mite fed up with this. I'll get Williams to check the charging rate and voltage, I can't believe that the car is pulling any power with the ignition off: the only device that is "always on" is the radio, it needs a non switched power line to retain station memory.
Any thoughts, collective?
