Battery alternative for DS3231 ?
According to the specs, the DS3231 rtc module wants a LIR2032, which is a rechargeable 3.6V lithium coin cell battery.
Can I use a regular CR2032 instead? My guess is that I can't, at least not without disabling the battery charging circuit on the DS3231. CR2032 are readily available where I live, but the LIR seems hard to find.
Alternatively, does anyone know where to get the LIR2032 shipped to Sweden?

[EDIT] I have removed Ebay sellers
@bjacobse have you had any luck getting ebay sellers to ship lion batteries? I've had the order cancelled multiple times.
Hello, it seems you have to cut a trace to disable charging.
@Nca78 sweet, thanks!

The first link was to a Danish site, they seems to sell
I have removed the chinese ebay links, since they wont sell overseas/airfreight
for LIR batt, maybe amazon, or i think conrad may have some but then the price...
I believe that the chinese can't send batteries with lithium, due to aviation rules..
Normally you are not allowed to put lithium batteries in checked in bagage either, when flying.
I desoldered the 201 resistor, found that easier than cutting the trace. Works great.
