I can buy a new 3rd party battery of t'Internet and there are instructions

So I've never got to the point where the benefit of a new battery
outweighs the risk of screwing it up.

So the answer you didn't ask for may be to replace the battery to get more
life out of your current SatNav.

I did this recently with my TomTom and, while the instructions sound
fairly scary, it's not too difficult as long as you take your time and
are reasonably careful.
