Hey folks,
I thought I'd share details of my recent experience trying to get a Cosmo battery replacement.
The battery in my Cosmo Communicator started to noticeably balloon, as of a few weeks ago. It was only slight, but the lid no longer completely closed (about 2mm gap), and the middle of the backplate was raised in the middle (about 1mm).
I emailed Planet to ask if they'd be able to send me a replacement battery. I really didn't want to part with my device, especially for an indefinite period of time, given I rely on it and how screwed up the international shipping network is right now. So I was preferring to install the new battery myself (or take it to a repair shop here in Melbourne, Australia).
I take it that it's not under warranty anymore (if it ever was, having backed it on Indiegogo).
Sadly, they said it was prohibited to ship the battery only, and needed me to send them the Cosmo. They'd install the battery for £75.00 plus £20.00 P&P. Surely posting a device containing a damaged battery is far less safe than sending an intact battery on its own, safely encased? And I thought the restrictions only applied to airmail anyway? I said I was happy to wait for surface mail (sea shipment) if necessary.
They responded saying the company needs to follow the rules governing shipping batteries; and that if I could find a suitable carrier to pick it up from them in London, they could do that. I spent a couple of hours researching last night, and could not find anything suitable for a reasonable price that would not leave Planet liable for potential mispackaging. I had no idea how arduous shipping is from the UK/EU!
Thanks to
this teardown guide thread, I discovered that the Cosmo and my now-unused Gemini use the same battery (SXX600). I disassembled both and installed the battery from the Gemini; I'll see if there's enough life left in it.
The 3rd-party battery linked from there is no longer available; I have ordered
this one just in case the one from my Gemini is not good enough. Whilst still expensive, this is significantly cheaper than sending my Gemini to Planet for a new battery (3rd-party battery =
AU $94.66 = £49.93. As opposed to:
£42.72 sending to them + their £75.00 & £20.00 P&P = £137.72 =
AU $261.11!)
I highly recommend that Planet Computers set up the ability to have batteries be sent from elsewhere (the factory in China maybe) where the restrictions are less.
Hopefully this information is helpful for others

As these devices age, I'm sure more and more people will be in need of new batteries!
It is so satisfying to have my Cosmo able to snugly snap shut again!
