"Wet" Storage

1. Store the batteries on a bench or shelf in a convenient location
and large enough to allow a little air space around each battery.

2. Place each battery upon wooden strips in order to keep the bottom
of the battery clear of the bench or shelf.

3. Apply Vaseline freely to the battery terminals, and to exposed
copper wires in the battery cables if the cables are burned directly
to the battery terminals. If the cables are not burned on, remove them
from the battery.

4. If convenient, install the necessary wiring, switches, etc., so
that batteries may be connected up and charged where they stand.
Otherwise the batteries must be charged occasionally oil the charging
bench.

[Fig. 151 Batteries connected for trickle charge]

5. Batteries in wet storage may be charged by the Exide "Trickle"
charge method, or may be given a bench charge at regular intervals.

6. Bench Charge Method.--Once every month, add distilled water to
replace evaporation. Then give battery a bench charge. See page 198.
Before putting battery into service repeat this process and just
before putting the battery into service, make the high rate discharge
test on it. See page 266.

7. Trickle Charge Method.--This consists of charging the batteries in
storage continuously at a very low rate, which is so low that no
gassing occurs, and still gives enough charge to maintain the
batteries in good condition. In many cases the "Trickle" Charge method
will be found more convenient than the bench charge method, and it has
the advantage of keeping the batteries in condition for putting into
service on short notice. It should, however, be used only where direct
current lighting circuits are available.

In the "Trickle" method, the batteries are first given a complete
bench charge, and are then connected in series across a charging
circuit with one or several incandescent lamps in series with the
batteries to limit the current. In Fig. 151, an example of connections
for a "Trickle" charge is given. The charging current for different
sized batteries varies from 0.05 to 0.15 ampere. The following table
gives the lamps required to give the desired current on 110 volt
circuit.

In each case, the lamps are connected in series with the batteries.
The "2-25 watt, (lamps), in parallel" listed in the table are to be
connected in parallel with each other and then in series with the
batteries. The same is true of the "3-25 watt (lam
