16. DETERMINATION OF

CAPACITY

a. A battery's capacity will, of course, decrease toward the

nd of its life. Assuming no specific cause of trouble, this

will be a gradual decrease and ample warning of limiting

capacity will be evidenced by the slowing of the truck or

other vehicle toward the end of the day's work.

b. A battery is usually considered to be at the end of its

usefulness when its capacity decreases below 80% of

ormal rating. However, it can sometimes be transferred to a

smaller job and thus give additional life and service.

18. WATERING

a. Use only approved water. That is 1) distilled water; or

2) de-mineralized water; or 3) local water that has been

approved for use in batteries. Never add acid, commercial

additives or other foreign material to the battery. Addition of

acid, commercial additives or foreign material may void

your warranty.

b. If there is some doubt as to whether the water being

used is suitable for use in lead-acid storage batteries, an

analysis should be obtained from a qualified laboratory,

otherwise, distilled or deionized water should be used.

Deionized water is available by using the EnerSys

PRO Clear Deionizer #94866.

c. Table 5 shows the maximum allowable impurities.

d. An EnerSys Watering Gun is a convenient and accurate

tool to aid in watering as it fills to a pre-selected height and

automatically shuts off; however, care must be taken to

adjust the watering gun so it will water cells to levels in

accordance with Figure 6.

c. Since the average motive power battery passes a “test”

every day by performing its regular work, it is seldom

ecessary to conduct a formal test of its capacity. Also, most

users do not have the facilities to do this conveniently or

accurately. If any such testing is desired, consult your EnerSys

epresentative regarding equipment and procedure.
