Tacktick batteries

[DaveyG]

My wireless wind reader uses Sanyo ML2430 (24mm x 3mm coin) rechargeable Li 3v coin batteries, ~£50 for a set of 2 replacements from Raymarine. Clearly, I can't possibly pay 10x the market rate for batteries, so I need to find my own replacements. Can't find the Sanyo ones anymore.

So, I have a choice, 3.6v 2430, or 3.0v 2450 - I think the 5mm may be a bit tight.

Anyone been down this path ?

Is it something like like this:
FDK - Lithium button battery ML2430-HS1 3V 100mAh: Amazon.co.uk: Electronics

Reminds me a bit of the 'capacitor' I recently changed in a Citizen Eco-Drive (solar powered) watch, I think that was basically a small button Lithium battery. I think the base battery might be a standard but there maybe some sort of metal conductors added, possibly propriety. Worth checking the original against the various photos in the link above. Cheaper than £25 each though.

The challenge seems to be spot welding the conductor rails to the two cells. If you know someone who is set up to do that ...

Might be able to make these fit:-

quick soldering - so as not to heat the li too much, or diy spot weld witha 12v lead battery -

I think there have been various threads on this on the yots and yotting forum
