1. Battery Characteristic
An auxiliary battery capacitor providing large pulse current.
Compared with the lithium SOCl2spiral battery, bobbin battery and UPC in parallel is more safety,and the combination can provide large discharge current compared with the single bobbin battery.
Low resistance, high power density, suitable for high current pulse;
Long life, using pulse cycle count up to 100000 times;
Good low temperature performance, wide temperature range from 40 ℃ to + 70 ℃;
Good safety performance.
The nominal voltage of single cell up to 3.6V, the operating voltage varies with the load, normally between 3.3V and 3.6V
Specific energy density up to 458Wh/kg
Battery working temperature range from -55℃ to +85℃
Battery voltage is very stable during work, more than 90% of the capacitycould be outputon a fixed high voltage platform
The battery self-discharge less than 2% per year at room temperature
Battery sealing using the fully sealed structure to reduce the leakage of the battery, make the battery can be stored at room temperature for more than 10 years
2. The working principle of UPC
Lithium SOCl2bobbin battery and UPC in parallel, high load of pulse completed by the Ultra Pulse Capacitor, not affected by the passivation.High load pulse bycompleted UPC, ahead of the next pulse lithium battery recharge UPC, after a full charge the discharge capacity ofUPC is constant, so on, until the battery capacity is completely consumed. In this way, we can guaranteethe battery packa long life under the high load capacity.

4. FAQS of General Safety Instructions
In order to store the battery, the environment should be dry enough.
You need to read our manual before you need the battery.
You need to keep battery out of the children. Please call to a physician immediately if it is swallowed by children.
When you put the battery into the devices, you need to follow the signs + and -. If they are put in the wrong way, they are going to be hot in very short time and it will lead the leakage of gas and toxic materials which may cause a big rupture.
They are going to be hot in very short time and it will lead the leakage of gas and toxic materials which may cause a big rupture.
The batteries are able to be deformed or drilled into or damaged because the toxic materials or gas leakage may lead a big rupture.
The batteries can’t be soldered directly. If they are directly soldered, it will cause short circuit and a gas and toxic material leakage or big rupture.
