Well so much for Maplins, they not got a clue!
I called them this morning and asked if they had an ML2030 T26 Battery and was told oh yes we have lots of them!
So I drive the 15 miles there to find out they only stock the CR2032 battery! Arghhhhhhhh
I try to explain i wanted an ML2032 with T26 fitting and not the standard CR2032 and was told they only tock the CR2032 and that would be fine. Maybe for around five seconds until it explodes as the CR2032 is no rechargable!
And thats asuming it does not blow up when i try and solder it.
So back to square one again, guess i'm left with ordering one from the link provided earlier.
