PAPR AirWave Blower Replacement Battery 14.4V Lithium Ion Inbuilt LED charge meter - TC180D PAPR - Standard Battery 18 Hour Run Time

A second battery makes good sense because it allows the best charging and depletion cycle which maximises battery life and ensures full duty cycle is achieved everytime.
The AirWave battery has a built-in LED charge meter so you always know how much charge is left before needing to switch off.  Just a note that moving from 99/% to 100% can add a further 10 to 15 minutes of charge time.
In general lithium ion batteries should be fully cycled, i.e. given a full charge operated until 30% or less charge remains then recharge fully.  Each time the battery is plugged in for charging is one charge cycle from the battery life of an expected life of about 500 charge cycles.

The battery makes use of your "USB - C" charge lead and charger supplied with your TC180D PAPR set - available as a spare part should you mis-place yours.

The TC180D PAPR - standard Lithium Battery has a 18 Hour Run Time.
Due to the advanced design and quality of the batteries the standard battery weight is only 284 grams.

Note that lithium ion batteries must never be stored with less than 35% charge otherwise the battery will fail and it will not be possible to charge the battery.  Therefore if you are not going to use the PAPR TC180D welding mask system then the battery must be charged before being stored.

Each AirWave battery has its own LED charge meter which indicates the level of charge, the last 1% to 2% of charge, from 98% to 100% charge takes a disproportionately long time, probably 15 to 20 minutes so please therefor be patient before removing from charge.
