https://devzone.nordicsemi.com/f/nordic-q-a/14154/nrf51822-with-3-6v-lithium-batteriesHi there, I know 3V lithium batteries (Lithium Manganese Dioxide) batteries would be perfect for the nRF51822, but we&#39;re wondering if Lithium Thionyl Chloride (Li-SOCl2) 3.6V batteries would work as well. The datasheet for the nRF51822 says the operatingen-USTelligent Community 13Tue, 31 May 2016 20:46:19 GMThttps://devzone.nordicsemi.com/thread/54082?ContentTypeID=1Tue, 31 May 2016 20:46:19 GMT137ad170-7792-4731-bb38-c0d22fbe4515:4501785e-d69c-4799-a9b3-ad1ee2504d91Kent Suzuki<p>Thank you Ole,</p> <p>Best regards, Kent</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/54081?ContentTypeID=1Mon, 30 May 2016 11:21:38 GMT137ad170-7792-4731-bb38-c0d22fbe4515:73f05552-79dd-4416-8b61-a05a04ce7adfOle Bauck<p>Do <strong>not</strong> operate the chip over 3.6V, this is the maximum operating voltage as specified in the datasheet. Yes, the absolute maximum is 3.9V, but as the datasheet says:</p> <blockquote> <p>Maximum ratings are the extreme limits the chip can be exposed to without causing permanent damage. Exposure to absolute maximum ratings for prolonged periods of time may affect the reliability of the chip.</p> </blockquote><div style="clear:both;"></div>
