SeaLife Li-ion Batteries Troubleshooting & Technical Updates

The following information applies to all SeaLife products using rechargeable Li-ion batteries.


Using Li-ion rechargeable batteries in extreme cold temperature

Li-ion rechargeable batteries, as well as all other types of batteries, will perform best at approximately 80°F (27°C). As temperature drops, so will the battery life. While Li-ion batteries can operate at sub-freezing temperatures, their run time will significantly drop to about 50% at extreme cold temperatures of -20°F (-29°C). When using Li-ion batteries in extreme cold, try to keep the batteries as warm as possible to extend battery life. It is also a good idea to have some fully-charged spare batteries on hand so you can quickly exchange batteries when needed.

Note:  Make sure to check the operational temperature limits specified for the UW light or camera that you are using.  Most underwater lights and cameras include minimum and maximum operating temperature.


Storing Li-ion rechargeable batteries

When storing Li-ion rechargeable batteries for more a few months or more, battery should be charged to about 50%. Batteries should be stored in a dry environment at room temperature (approximately 70°F/21°C to 80°F/27°C). This will help to maintain the battery’s life and performance.
