If the vehicle is equipped with 12 volt batteries as shown in Figure
4.2.2, they will require watering.
The cell vents are located below the covers (Figure 4.2.2 Arrows).
Do not overfill batteries. Electrolyte expands and can overflow during charging. Water added to replace
the spillage dilutes the electrolyte and reduces its specific gravity.
Use only distilled water. Vehicle batteries may use up to 16 quarts of water during their useful life and
non-distilled water may contain harmful minerals which will have a cumulative adverse effect on battery
performance and life.
Be sure battery hold downs are properly tightened. A loose hold down may allow the battery to become
damaged from vibration or jarring. A hold down that is too tight may buckle or crack the battery case.
Weekly inspect battery posts, clamps and cables for breakage, loose connections and corrosion. Replace
any that are damaged. Check to see that battery cap vent holes are clear. Plugged vent holes will not
permit gas to escape from the cell and could result in battery damage. Batteries and connections must be
clean and dry. See Section 4.3.
Weekly an equalization charge is to be applied to the battery pack. This process balances the electrical
charge in the battery pack and will extend battery life. The following procedure is used to complete this.
Charge the battery pack allowing the Delta-Q Charger to go to green 100% charge.
Once the green LED lights unplug the power cord.
Wait approximately 30 seconds. Reconnect the power cord and allow the Delta-Q to complete a
second charge cycle.
If the vehicle is not to be used, leave power cord connected. The Delta-Q can test and recharge as
needed.
4.3 BATTERY CLEANING
Acid-soaked debris on the battery terminal connections will cause current leakage, reduces battery
efficiency, and battery life.
Check that all vent caps are tightly in place. Hose wash battery terminal connections periodically with
clean low-pressure water to keep them free of acid spillage, dirt, and other debris. Do not hose wash
electronic controllers, switches, solenoids and other electrical control devices. Cover as necessary to
prevent splashing.
Clean battery terminal connections with baking soda (sodium bicarbonate) and water solution. Mix 5
teaspoons baking soda per quart of water. Use a stiff bristle brush, rinse with clean water and dry with a
clean cloth. Do not allow solution to enter cap vent holes.
NOTICE:
Follow local ordinances and codes for proper disposal of battery cleaning waste.
4.4 CONDITIONS WHICH AFFECT CHARGING
Always schedule enough charging time so the Delta-Q Charger attains the 100% level. Charging time is
affected by age and battery condition, state of discharge, electrolyte temperature, AC line voltage, and
other variables. Correct charging methods extend battery life and vehicle range between charges.
