AN/CYZ-10(V3) DTD…
The batteries
and battery
compartment on
the AN/CYZ-10 data
transfer device
(DTD) are your
most important
preventive
maintenance
concerns.
Good preventive
maintenance on the
DTD means
three
things…
using the right
batteries,
installing them right,
and
keeping good
contacts.
One final option is “for
emergency use only” and
that is a 9-volt battery. A
9-volt lithium, NSN 6135-
01-369-9792, or alkaline,
can be used, but neither
one will last as long as the
BA-5123/Us. However,
the lithium will last longer
than the alkaline.
Also, they will not sit
as well in your battery
compartment. You may
need some “stuffing” to
keep the batteries snug in
the compartment.
The DTD uses three 3-volt lithium
batteries, BA-5123/U, NSN 6135-01-
351-1131.
Don’t substitute look-alike batteries
like the BA-5372/U for the BA-5123/U.
The last guys who did that are buying
new DTDs to replace the ones that were
destroyed by the high heat produced by
the BA-5372/Us.
A future alternative to the BA-
5123/U is the rechargeable 9-volt
NiCad, NSN 5810-01-501-5401. Right
now, only Navy folks can order it, but
check FED LOG in the future, because
the move is toward using rechargeable
batteries whenever possible.
Before you insert the batteries, make
sure they are fresh. Meter them. Good
batteries will meter out between 9.25
and 9.50 volts.
Don’t use batteries that fall below
this range or your DTD might soon
become erratic, intermittent or even
lock up.
Using the Right Batteries
Here’s an
additional tip for
shop use… Go
with the battery
eliminator (an
alternative power
source), NSN 5810-
01-461-1149.
Over the long
run this will
save battery
bucks and is
good for
testing, training
and software
loading.
Use 3-volt lithium batteries
No look-alikes!
Emergency?
9-volt Lithium
can be used
9-volt might
not be tight
