STOCK CHARGING Proper Instructions for Wet or Dry Batteries in Stock
Wet Batteries
1. Wet Batteries will discharge over a period of time sitting on the shelf.
Because of this they need to be given a periodic charge to bring them
back to full charge.
2. These wet batteries would be given a charge every:
(see charging section) :
a. 9-12 Months-Calcium Automotive and Group 31.
b. 5-7 Months-Low Antimony, Hybrid and Barium.
c. 3-4 Months-Low Antimony Commercial, Specialty and Automotive Batteries.
Note: In hot climates or warm storage areas, a battery's state of charge
should be checked more often.
3. Periodic checks on batteries in stock should be made to assure that batteries
are fully charged.
4. They all should be given a slow charge (see charging section) until the
hydrometer reaches 1.250 or higher in all cells. The reason for the slow
charge is because batteries should be recharged in the same manner they were
discharged-slowly, over a period of time, to assure that they are sufficiently
pharged.
As batteries discharge, sulfation begins to set in. This sulfation needs to be
broken down slowly, so it's broken off completely. A fast charge will not
adequately penetrate the sulfated plates, the battery only receives a surface
charge. At the first draw upon the battery, the surface charge is removed and
the battery is back to its previous state-of-charge (surface charge is simply
a charge on the Surface of the plates, not having penetrated the plates) .
Dry Batteries
When preparing dry batteries for activation to be sod as wet, the following steps
need to be observed.
1. Fill each cell to the bottom of the vent well with electrolyte only.
2. Vent caps must be firmly in place before charging. This is to prevent any
possible chances for explosion (when charging). If possible, place a damp
cloth across top of battery vent caps, to also aid in preventing the chance of
~ny explosion.
3. Le
t,
the batteries set for at least 15 minutes to allow the electrolyte to soak
in to the plates.
4. Charge each batterY at the following rates:
a. 12 Volt Battery: 30-40 Amps
b. 6 Volt Battery: 60-70 Amps
Charge until hydrometer reading is 1.250 or higher (see charging section) .
5. After sufficient charge cycle or cycles have been completed, check the
dlectrolyte level. If necessary re-fill to the bottom of the vent well
(electrolyte only) .
