Primary lithium

Primary (Non-Rechargeable) Lithium Batteries

A primary lithium battery is used once and not recharged. It has a long shelf life and a steady voltage, so it suits devices that must run for years on one battery, such as meters, trackers, sensors and memory backup. Jetray supplies primary lithium batteries from Panasonic, Maxell, FDK and Seiko.

Types we supply

TypeNominal voltageTypical usePage
Lithium thionyl chloride (Li-SOCl2, ER series)3.6 VUtility meters, asset trackers, alarms, IoTLi-SOCl2
Lithium coin cells (CR series)3 VKey fobs, sensors, clocks, small devicesCoin cells

Other primary types may be available on request. Tell us the size and the load.

02

Primary or rechargeable?

Choose primary when the device is used little, must last for years, or is hard to reach. Choose rechargeable when the device is used often and a charger is practical.

03

For OEMs and distributors

Batch supply

For device makers that build the battery into their product.

Versions with leads, tabs or connectors

For products that need to be soldered or plugged.

Distributor supply

Of standard sizes.

MOQ depends on the model. For coin and button cells it is 4,000 pieces. Send your quantity and we confirm.

04

Documents and shipping

Lithium batteries are regulated goods for transport. UN38.3 and MSDS documents are available. Tell us the model and we confirm which documents cover it. We ship worldwide from Shenzhen.

Li-CFx (BR)3 VLong life at low drain, wide temperature rangeMemory backup, industrial

Check the datasheet for exact performance.

06

Estimating battery life

A simple estimate: capacity in mAh divided by average current in mA gives hours. For a device that sleeps most of the time, average current includes the sleep current and the short wake-ups. Add margin for temperature and age. Send us your current profile, and we help with a better estimate.

07

Storage and handling

  • Store in a cool and dry place.
  • Keep the batteries in their packing, so terminals do not touch metal.
  • Do not mix new and used cells in one device.
  • Do not charge, crush, heat or open a primary cell.
  • Follow local rules for disposal.
