Batteries
BATTERY WARNING. Lithium ion batteries may explode or burn due to improper use. Careful
attention should be paid to your battery suppliers safety recommendations.
The SoundTrap ST400 is powered by 2 Panasonic NCR18650B (flat top) lithium-ion batteries. These
are loaded individually, meaning you can use one or two batteries. However we recommend loading
both batteries to provide a level of redundancy.
We strongly recommend only using Panasonic NCR18650B (flat top) batteries.
These are commonly
available and all testing and advertised battery endurances assume use of NCR18650B batteries.
Performance of other brands is unknown. Untested brands may leak acid, potentially causing
damage to the electronics. Source the batteries from reputable suppliers to avoid inferior
counterfeits.
Be careful to ensure correct battery polarity as indicated by the diagram in the battery
compartment. Once loaded, double check each batter
y’s
polarity.
18650 batteries are generally supplied in a partially charged state and should be recharged prior to
first use. Recharging requires a good quality lithium-ion battery charger such as the XTAR VC4 or
similar.
When not in use, batteries should always be removed from the recorder and stored in a fireproof
container. If the batteries are not to be used for a long period (more than a month) they should
ideally be stored in a half-charged state in order to maintain future performance.
