Sec. 111.15-5  Battery installation.

    (a) Large batteries. Each large battery installation must be in a

moderate battery installation is in a ventilated compartment such as the 
engineroom and is protected from falling objects, a box or locker is not

all around each tray. Each battery tray must provide adequate 
accessibility for installation, maintenance, and removal of the 
batteries.
    (e) Nameplates. Each battery must be provided with the name of its 
manufacturer, model number, type designation, either the cold cranking 
amp rating or the amp-hour rating at a specific discharge and, for a 
lead-acid battery, the fully charged specific gravity value. This 
information must be permanently fixed to the battery.

electrolyte of the battery.
    (3) For alkaline batteries, the lining must be 0.8 mm (\1/32\ inch) 
thick steel or other material that is corrosion-resistant to the
