In a Li battery, the thermistor is for safety. It's slovenly manufacture not to include such a cheap item, but won't affect the operation of the pack. Most likely is that your new battery has a pitifully small capacity, and the nominal mAh figure is just that (nominal - with no bearing on reality). In a Li battery, the thermistor is for safety.
The battery explosion threshold temperature depends on the specific chemical compounds in the lithium ion battery. Different NTC thermistor designs are being used depending on the temperature limits. For the widely used lithium cobalt oxide batteries in consumer electronics the upper safe temperature limit is 130 °C to 150 °C.
Only batteries with three terminals or more will have thermistors inside, two terminals means no thermistor, however you can use a battery protection pcb. Yeah but I hear it only protects from over/under charging.
Only batteries with three terminals or more will have thermistors inside, two terminals means no thermistor, however you can use a battery protection pcb. Could you use a thermal fuse (like this )? This would only require two wires. You would of course have to select a temperature suitable for your application.
The thermistor is located on the battery because that's the temperature one is monitoring. The thermistor seems to have no control function, but is simply a sensor that when connected to an appropriate lipo charger gives a temperature measure that is used to shut down charging should the battery overheat.
The thermistor has no control function, but is simply a sensor that when connected to an appropriate lipo charger gives a temperature measure that is used to shut down charging should the battery overheat. It could in principle also be used to vary the charging characteristics to optimize charging at any given normal temperature.
