PRECAUTIONS NEVER smoke or produce a spark in the battery area. When performing battery maintenance wear safety glasses, rubber gloves and protective clothing. When using a hydrometer avoid letting the rubber tube shake as this can cause drops of electrolyte to splash onto your clothing or into your eyes. Store your hydrometer in a clean dry place.
INSTALLATION – Continued STEP 2 Inspect the battery and tray for evidence of damage, if damage has occurred file a claim with the carrier immediately. If you see liquid on the top of the cells pour some neutralizing agent into a small container and apply with a clean paint brush.

INSTALLATION – Continued WARNING: The weight inside the plastic cells will cause the sides to bulge when removed from the tray. This is normal, however, use caution when handling the cells. Any pressure on the sides will cause the cells to “breathe”...
INSTALLATION – Continued STEP 10 Install the lid by taping the hinge pin back into the can hole. When you install the lid you have a choice of where the hinges are located. Some lid hinges use an internal hex head bolt, use an Allen wrench to remove and replace the lid.
HYDROMETER Insert the rubber tip into the cell but not into the electrolyte. Squeeze the bulb and lower the rubber tip into the electrolyte and release the pressure from the bulb. The barrel will fill up and the float will rise. It is very important for the float to be freely suspended in the electrolyte.

VOLTAGE – Continued FULLY CHARGED VOLTAGE READINGS On-charge voltage readings are most informative and are good indicators of battery condition. These readings should be taken when the battery is approaching full charge with 2% of the battery capacity flowing into the battery. New batteries, when fully charged and 2% of the battery capacity flowing into the battery, will have cell voltages between 2.55 –...
SPECIFIC GRAVITY The standard fully charged specific gravity for the HAWKER PV-1 Solar Battery is 1.275 – 1.285 at 77˚ F (see Fig. 4 and Fig. 5 on page 14) and the 100% discharged gravity is 1.140. Since the acid content of the electrolyte decreases linearly as the cell is discharged, the decrease in gravity is directly proportionate to the amount in ampere-hrs taken out.
EQUALIZE CHARGE The term “equalize” simply means a controlled overcharge. This procedure is used to adjust the difference between cells that develop due to temperature variations within the battery, manufacturing, and cycling of the battery. The equalize charge will also help scrub off sulfate particles that tend to build up on the battery’s positive plate.

SULFATED BATTERIES – Continued Cells of a sulfated battery give a low specific gravity and voltage reading and the battery will not become fully charged after a regular equalize charge. Before assuming that the battery is sulfated, rule out the possibility that low specific gravity may be due to acid loss.
TROUBLESHOOTING PROBLEM PROBABLE CAUSE REMEDY Battery not 1. Battery is undersized 1. Replace with a larger battery performing as 2. Battery not fully charged 2. Check charger and controller expected. 3. Weak or defective cells 3. Perform a load test 4.

MAINTENANCE WEEKLY 1. Record hydrometer reading of pilot cell (the cell with the lowest specific gravity when you first received the battery). Once a year select a different cell to be the pilot cell. 2. Check the water level (add as needed). 3.
RECORDS ENTERING DATA IN THE WEEKLY FORMS It is essential that you label each cell for these records to aid in the operation of your battery. This form is designed to enter general battery information on a weekly basis and will, at a glance, show any abnormalities in the battery’s health.
