Battery Features:  

D SIZE BATTERY.jpgRecommended battery model parameters:

Battery model: D Size battery,LR20 batteries,ER34615M, High drain ER34615

Battery brand: SER

Battery performance index

1. Battery capacity: (23±2℃, 2.0mA/2.0V) 14.5Ah

2. Open circuit voltage: ≥3.64V

3. Load voltage: (8Ω, 20±5℃, time ≤10s) ≥3.20V

4. Continuous working currents: 1800mA (at 25℃ 2.0V cut  off, up to 50% of nominal capacity)

5. Large pulse working current:  3500mA    

(100mA/0.1s pulse, drained every 2 minutes at 25℃ from 1mA mid-charged cells with 20μA base current, yield voltage readings above 2.7V, the readings may vary according to the pulse characteristics, the temperature, and the cells’s previous history.)

6. Operating temperature range: -55~+85℃

7. Battery storage life: 10 years

  (Storange condition: clean, cool (preferably below +20℃, not exceeding +30℃), dry and ventilated.)


Do not recharge, short circuit, crush, disassemble, heat above +100℃, incinerate,or expose contents to water. Dispose of used batteries properly in case of explosion, burn and leakage.

Eight Advantages

The main raw materials are all imported from abroad, and the sealed lithium battery produced is novel in technology and has the following notable features andeight advantages:

1. The energy density is as high as 680Wh/kg, which is the highest among various lithium batteries.

2. High and stable operating voltage; open circuit voltage up to 3.66 volts, working voltage varies with load, usually between 3.3~ 3.6V

3. Low self-discharge rate: the annual self-discharge rate is less than 2%; the storage life can be 10-15 years at room temperature.

4. Wide temperature range: -55℃~+85℃.

5. The working voltage is stable: more than 90% of the battery capacity is output on a high-voltage platform with almost constant voltage.

6. The Li-SOCL2 battery is hermetic glass-to-metal sealing, well sealed, safe and free of leakage.

7. Non-flammable electrolyte

8. Good safety record, pollution-free products fully meet the requirements of UL, CE, UN, do not contain mercury, cadmium, lead and other heavy metals, no environmental hazards.

Energy-type Lithium Thionyl Chloride battery (including standard energy type and high-capacity type) generally works continuously for a long time with micro-current, and can provide medium-current pulses, and the working time can be as long as 8 years

Power-type Lithium Thionyl Chloride battery can be designed in different ways according to different uses. Generally, it mainly provides high current or high pulse current. At the same time, it can work continuously for a long time with low current, and the working time can reach 8 years;

High temperature Lithium Thionyl Chloride battery can be used in the temperature range of -40~125℃.
