3.7 V 500mAh Lipo Batter Rechargeable Lipo  Battery LP552540 for Fetal Heart Rate Monitor

The fetal heart rate battery is a 500mAh lipo battery. The 500mAh battery has stable power supply, no noise, and no infrasound. This is the best choice for Fetal Heart Rate Monitor. The polymer lithium battery has superior electrochemical performance, excellent processing performance, and large tap density, which helps to increase the battery volume specific capacity, product performance is stable, and consistency is good. PCM makes with Japan IC & MOS, it makes the battery much more safety.

The fetal heart rate monitor detects and measures the fetal heart rate in real time to assess the health of the fetus, digital filter noise reduction technology, clearly listen to the rhythm of new life, and wireless integrated technology to improve its convenience and comfort. To monitor the fetal heart rate yourself at home is to find a way to communicate with the baby and take a more practical way for prenatal care. As more and more companies sell personal fetal Doppler instruments, it seems to be an attractive proposal for moms.

Lipoly battery Life?
Standard: After 500 cycles, the capacity will be <80%.
It will be affected by the situation of discharge/recharge, and battery environment like temperature, humidity.

What is room to swell of lipoly battery?
Lipoly Battery will have a sligh swell in the charging. So it will affects your mechanical design? The answeri we gave is that you do not have this worry about these.
Because all lipoly battery we produced have reasonable tolerances:
Thickness tolerances is ± 0.3mm,
length is ± 1.0mm,
width is ± 0.5mm.

What’s more, the swell usually only affects the thickness of the battery, and it is within our tolerances. It means that thickness tolerances is ± 0.3mm (Maximum tolerances is ± 0.5mm), that is swell range.
