Battery for Tacktick Micro Compass

Originally posted by ian.r.mcdonald is it the small market that stops a manufacturer coming to the market with a competing product with a replaceable battery? tacktick seem to have lost the replacement market to the diy replacers and they must be losng more sales than the few gained because batteries are not easily replaced? surely a new supplier would clean up?

Surely the battery replacement market is pretty slim anyway?
My tacktick is pretty old and has not needed a battery.
I don't race at night and it spends a lot of time on a window cill FWIW.
It's about time there was a much cheaper product though!

Great news

Velocitek Shift offers a replacement battery; has higher initial price, but will level off if/when you replace the battery.  Has bigger numbers, compass displays during countdown and smarter compass.

This looks like it might be close enough to work.
It's, rechargeable, the right 3.0V, has pins for a PCB.
Only 50mAh instead of 100, and the pins may not be in exactly the right place.

Is there space for a bigger diameter?

It looks like you won't get 100mAh in 24mm diameter these days.
Coin cell numbers are e.g. 2430 = 24mm diamter, 3.0mm thick BTW.

HTH?

Obviously check the polarity if fitting a slightly different part.
