I'm beginning to think the battery in my Motorola G5 is not long for this world, and it doesn't look like there are a lot of options locally for purchasing a replacement.

Battery is a GK40 which a small number of other Motorola devices also use.

FoneFix can supply an official Motorola Replacement battery but are by far the most expensive option I've seen

A lot of the other retailers appear to be off shore sites with local domain names. Plus a lot of other online retailers won't ship a lithium battery to NZ.

Any local options I've missed?
