PKCELL ER14250 ER14505 ER26500 3.6V LI-SOCL2 Battery Packs Manufacturer

Short Description:

Certification: UL / RoHS/UN38.3


Li-SoCl2 cells offer a notable advantage over other primary battery chemistries in terms of high voltage stability. Unlike alkaline or zinc-carbon cells that exhibit voltage drops as they discharge, Li-SoCl2 cells maintain a relatively constant output voltage throughout their discharge cycle.

1. High energy density (620Wh/kg); Which is the highest among all lithium batteries.
2. High open circuit voltage (3.66V for single cell), high operating voltage with load, normally ranging from 3.3V to 3.6V).
3. Wide range of operating temperature (-55℃~+ 85℃).
4. Stable voltage and current, over 90% of the cell capacity is discharged at high plateau voltage.
5. Long operating time (over 8 years) for continuous low current discharge with medium current pulses.
6. Low self-discharge rate (less than 1% per year) and long storage life (over 10 years under normal room temperature).
