Hi Timd1971,
We are an Australian distributor and carry plenty of stock and some limited spares, although not batteries.
We can supply RS+ units very quickly.
For anyone with battery issues I would recommend upgrading to the latest version of Reachview and leaving your units on charge for at least over night (as a one time measure), regardless of battery status indicating 100% charge.
FWIW, we charge overnight and check each unit we supply prior to shipping to our customers. We’ve only had one returned and that was due to a diode that was I talked back to front, an issue peculIar to a small batch of Reach RS (not RS+) that prevented fix,
This doesn’t answer your battery replacement question but I hope this helps, Al
