Anyone knows what are the specs of this battery?I would like to order the replacement but I’m not sure if this one is the one:https://www.aliexpress.com/item/10050034…
Grzegorz Baran the battery for this device is a AHB330945 9429011-1891 0.4Wh 3.7V dc You could possibly use the battery you have linked to but it is not an exact replacement. You may have to “fiddle” with it to make it work.
