Ever since I replaced the battery in my suunto vector, it plays up every now and then, The time and date change to 18:00. sat 1-1-00
has any one else had any problems after changing the battery?
It was the way I knew the battery needed replacing, suddenly find it showing the wrong time and date reset. I would keep resetting the time but fairly soon the display would fade and then it had to ne a new battery. Most likely your new battery is a dud.
Is it a cheap battery?
If put £1 shop batteries in my Core it is fine for a bit and then plays up, before running out after a month.
A proper Duracell or similar will last dozens of times longer
