Cells OK no top up needed.
To view rating of current battery you have to take off battery clamp and it's detailed under
there.
Unfortunately when I removed the clamp bolt [on the engine side], after removing
nut, the threaded rod dropped into engine bay. No luck locating, so off to Mazda in morning!
There's also need to reset the Stop /start.
Found a useful YOUTUBE video on how to reset the iStop [STOP/ START] feature when you change the battery ; personally I don't miss it, as on my CX5 hasn't worked for a time, which is down to battery voltage being somewhat low (12.06v).
Procedure also requires some resetting steering wheel settings.
