Can anybody provide me a linear section of rechargable LiIon battery

Terry

I'm using nRF51822 for development. and I want to use ADC to measure the electricity of battery, but I don't know the discharge characteristic, i couldn't get that on internet. and DEMO in the SDK only shows the CR2032's linear section. Can anybody show me the rechargable LiIon's linear section?

    Hi Terry,

    Most of my experience is with CR2032, not Li-ION. However, none of these two discharge linear. The tricky part with lithium-ion batteries is that most of them have different characteristics, so this is not a "one fits all" kind of operation. The best bet is to check the characteristics for the battery you're going to develop with and create a lookup table based on the measured ADC value.

    If you google "lithium ion discharge curve" you will find many articles and plots regarding this topic.

    Best regards Håkon
