Key Takeaways: Common signs of a bad lithium-ion battery are a high self-discharge rate, frequent overheating, low voltage, reduced capacity, and swelling. However, the sure way to tell if it''s bad is to measure its performance and compare it with the manufacturer''s specifications using a Capacity and discharge test and a Voltage output test.
The other problem is that if you use a DC-DC converter, your current will not be constant. As the voltage decreases, the load current will increase. As a practical matter, what is usually done is to use the battery average voltage (3.7 in your case) and the current at average voltage for the life calculation.
This represents a large current from a relatively small battery of about 800 milliampere (mAh) hours. A current pulse of 2.4 amperes from an 800 mAh battery, for example, correspond to a C-rate of 3C. This is three times the current rating of the battery. Such high current pulses can only be delivered if the internal battery resistance is low.
