been designed for users.

The bands are red, green and black. When the hydrometer test shows the
bottom of the red band in the electrolyte, the battery, whether in
glass or rubber jar, is discharged. When the top of the green band is
out of the electrolyte, the glass jar battery is charged. The top of
the black band out of the electrolyte indicates the rubber jar battery
is charged.

When and How to Charge Battery

Plants with Average Loads

Loads of legs than ten (10) amperes can be taken directly from the
battery, until:

1. The large hand on the ampere-hour meter reaches 12, or

2. Both pilot balls are down, or

3. Hydrometer test shows bottom of red band in the electrolyte.

If any or all of the three gauges listed above show the battery
discharged, the plant should be started and operated continuously
until the battery is charged, as indicated by:

1. Ampere-hour meter hand at FULL, or

2. Both pilot balls UP, or

3. Hydrometer test shows top of FULL band out of electrolyte.

(NOTE: Any one or all of the above three items may indicate battery
charged. Meter hand at FULL would necessitate both balls UP. If both
balls are not up, set hand back and charge to bring them up; then set
hand at FULL.)

Should the user be operating for two or three hours with a seven or
eight-ampere load, it would be more efficient to run the plant to
carry this load. This only applies for those cases where the battery
is partly discharged.

Carry Heavy Loads Greater Than 10 Amperes.

If there is a constant load of 10 amperes or more, the plant should be
started up when the heavy load comes on. When the heavy load is off,
the plant may be stopped, but it would be entirely satisfactory to
allow the plant to continue to run until "Charged," as indicated by:

1. Ampere-hour meter hand reaches FULL, or

2. Both pilot balls are UP, or

3. Hydrometer test shows top of FULL band out of electrolyte.

In any case, plant should be run until battery is "Charged" at least
once a week.

Always Start Charging When Battery Gauges Indicate Battery Discharged.

On ampere-hour meter plants, when the hand is at FULL, the plant
cannot be operated on account of the ignition circuit being broken.

In such cases allow load to be taken from the battery until the hand
travels back sufficiently to allow the plant to run.

Occasionally the plant and battery are used to carry continuous loads
of from 10 to 15 amperes each night,
