TECHNICAL MANUAL
Observe the following precautions when installing batteries:
•
Make sure the batteries you install conform to local building, fire and safety codes.
Some battery types emit hydrogen gas during the charging state and may require
venting to fresh air.
•
Do not place batteries directly on a concrete floor. This causes them to discharge
very quickly.
•
Follow the battery manufacturer's recommended installation and maintenance
procedures.
