We’ve seen too many projects stall mid-cycle because a battery couldn’t keep stable voltge under load, especially in tempearture swings or low-drain conditions, and that’s where the CR1632 actually earns its keep with its 125mAh capacty and tight discharge curve.

Basically, this is a 3V lithium manganese dioxide cell at 16mm by 3.2mm, weighing just 1.6g, so it fits anywhere you’d normally squeeze a coin cell.


shelf life is about 5 years or so, and teh operating range is -20°C to +60°C — (we usually have stock in bulk, but confirm lead time for card packing since MOQs vary).

It’s not suited for high-drain appliction like LED flashes or motors, but for car keys, digital scales, and medical monitors it runs steady and doesn’t drop voltage early.
We can start from as low as 1,000 pieces per model. If you need smaller quantities for testing, just ask and we can work something out.
If the model is in stock, we usually ship within 3-7 business days. For larger orders or custom packaging, lead time may extend to around 15-20 days.
Yes, we have RoHS, ISO9001, and SGS certifications on file. We can share the certificates and test reports with you before the order.
Yes, our 125mAh rating is tested at a standard discharge current of 0.2mA down to 2.0V at room temperature. Actual runtime varies depending on the device's power draw.
Absolutely, we offer both bulk and card packing options. Just let us know which type you need, and we'll adjust the packaging accordingly.
