3.4.2 Lithium-Ion Batteries (LIBS) - 2500-36TSC (01532104) and 2500-30TSC
(01532116)
The 2500-36TSC supersedes the 2000-36 and 2000-36T LIBs.
The 2500-30TSC supersedes the 2000-30 and 2000-30T LIBs.
The functionality and performance of the 2500 Series LIBs is equivalent to those LIBs they supersede and they may be used
interchangeably relative to performance and application.
CAUTION
The power cord for the 2500 Series LIBs has a different cord-to-battery connector (A) and this cord must be used with
the 2500 Series LIBs, and not the older cord (B). The new cord is also compatible with the older style LIBs.
The older cords do not connect reliably with the 2500 Series LIBs and must not be used with these new LIBs.
When you purchase a 2500 Series LIB you will receive new power cords for each of the MAXAIR Helmets you have purchased
over time. You must discard all older power cords when you receive your new 2500 Series LIBs to ensure you are always using
the correct connector, regardless of newer or older battery.
NOTE
The 2500 Series LIBs incorporate a Secure Lock Button and mechanism that securely locks the power cord connector,
from the helmet, into the battery connector. The operation of this Secure Lock Button is described in all appropriate
sections of the User’s Instructions.
If you have questions about the newer versions described in this section, please contact Customer Service at
info@maxair-systems. com, or 1-800-443-3842.
