Automotive, marine, and deep-cycle batteries typically
have a pair of slots or lips at the base of the battery for mount- − Socket

ing purposes. Figure 3-35 shows a typical automotive style +
mounting tray for a lead/acid battery. These types of mounts
Button
are very secure and are appropriate for several applications.
For lead/acid batteries that do not have clamping provisions a Mini Snap
clamp frame as shown in Figure 3-36 is typically used. This Screw − +
mount generally consists of a battery tray and an upper frame.
The frame is secured with two or four clamp bolts that run − + Spring
down to tabs on the tray. It should be noted that the clamp
frame used in this type of mount is generally constructed of
plated steel. Great care should be exercised to avoid shorting
the battery terminals when installing the frame.

There are nearly as many different types of battery terminals
as there are battery types. Terminals can generally be grouped
into three different categories, dry cells; sealed lead/acid bat-
teries; and automotive, marine, and deep-cycle batteries. Battery Connectors
Figure 3-37 shows common terminals that are found on stan-
dard dry cells. These range from screw terminals to spring- Most batteries will either accept standard electrical connec-
loaded terminals. Figure 3-38 shows terminals that are generally tors or provide a screw terminal for connecting bare wire.
