3.6V NON Rechargeable C size lithium thionyl chloride battery with solder tabs; 9000 mAh; wide range of temperatures -55C to +85C; most suitable for low power consumption devices.CERTIFICATIONS RoHS and UN 38.3 compliant; UL and IEC certified. MANUFACTURER DIRECT All of our batteries have date-code to guarantee freshness. Lithium thionyl chloride battery has a passivation characteristic. Therefore, we highly recommend customer to use the battery within 3 months to receive optimal performance. Although our battery has a 20-year shelf life (under special storage conditions), we advise customers not to store batteries for a long time due to the passivation characteristic. It is highly recommended that you purchase as many as you need. If you plugged in the battery into your device and it appears to be “dead” or half-charged, it is usually due to lithium batterys voltage delay or passivation.
