So I just need to buy the exact same battery as it and replace it when it runs out of power?There are rechargeable lithium button cells available but the 'CR' on the cell in your picture implies that it is a primary cell - not rechargeable - and so needs to be replaced when it is flat.
Don't ever attempt to charge this cell. It will explode. Disastrously.
Thanks for your enthusiastic reply, I will check it out and buy some.hi,
There are LiR 2032 rechargeable types, but they are rated at 3.6V.
You would have to add suitable charger circuit, the regular CR2032 would be easiest option to replace.
BTW: In case you did not know the 2032, means 20mm Dia and 3.2mm Thick.
1 x CR2032 Li-ion rechargeable button cell battery 3.6V Lir2032 replaces all CR2032 Lithium 3V. Very cost-effective: A rechargeable CR2032 replaces 200 lithium CR2032 disposable battery cells Capacity: 40 mAh rechargeable 500 times. Dimensions: 20 mm x 3.2 mm. Weight: 2.6 g. Compatible models: CR2032,
