6.2 Ventilation
Although the ATP and ATLP series of batteries are valve regulated, they do produce minimal gas
emissions during normal operation. If exposed to abnormal high voltage charging, the cells may vent
potentially explosive hydrogen gas. Hydrogen gas when accumulated in a confined area that exceeds four
(4%) percent by volume in air is explosive. C&D recommends not allowing hydrogen gasses of greater
than two (2%) percent by volume to accumulate. Contact the local code enforcement officer to determine
what codes and levels are applicable to your battery room installation. Lead acid batteries should never
be installed in a sealed, non-ventilated cabinet or enclosure.
VRLA batteries subjected to extreme overcharge voltages have the potential to release hydrogen gas at a
rate of 0.000269 cubic feet per minute - ampere of charging current at 77°F (25°C). The msEndur II
series testing shows that they recombine at nearly 99% efficiency under normal conditions. However,
compliance with codes and appropriate safety measures regarding hydrogen evolution is essential for the
safety of the equipment and personnel.
6.3 Floor Loading and Anchoring
Floor loading and anchoring requirements are the responsibility of the user/installer and all applicable
building codes and regulations must be followed. C&D provides connection drawings, weights,
dimensions, and floor loading information on our system drawings for reference.
The msEndur II floor-mounting base has provisions for floor anchoring. Consult the applicable building codes
and regulations for specific requirements. In all cases, floor anchoring is considered mandatory with floor
anchors to be installed in all locations provided unless otherwise specified. Floor anchor sizing and
hardware are the responsibility of the user/installer.
6.4 Spill Containment
Although the msEndur II series of batteries contain no free flowing electrolyte, it is the sole responsibility of
the user/installer to follow all local building and fire codes applicable to the battery installation. It is
recommended consulting the local fire marshal or building inspector to determine if spill containment
is required.
If required, spill containment can be purchased from C&D. Please contact your local C&D representative
or C&D Customer Service at 1-800-543-8630 or +1-215-619-2700 or email: [email protected]
