Special order batteries may be shipped dry (acid shipped separately).
To activate these batteries, start by removing the vent caps. Using approved battery grade electrolyte (1.265), fill each cell half way between the plates and the bottom of the vent well tube. It is important not to over fill the cells as the acid will expand upon charging.
If the cells are too full, the acid will spill out of the top of the cells. Allow electrolyte to saturate into the plates and separators for at least 90 minutes. The temperature of the electrolyte will rise and the specific gravity will drop. Once this is complete, place the batteries on charge at the finishing rate (5% of the 8 or 20 hour rate). The rate may be increased if the battery does not begin to gas. Do not let the cell temperature exceed 115° F (46° C). If the temperature becomes excessive or the cells begin to gas vigorously, reduce the rate of charge. Continue charging until the cell (or cells) reaches within .005 points of the specific gravity of the filling electrolyte corrected for 77° F (25° C).
We recommend to continue charging for an additional 60 minutes to insure no further rise in specific gravity.
Top up or remove electrolyte as necessary for proper level. Never add electrolyte (only approved water) after activation. Replace vent caps and remove any spillage of electrolyte. If necessary, clean with bicarbonate of soda and water (100 grams of soda to one liter of water). Rinse with water and wipe dry. Ensure that soda solution does not get into cells.
*Do not place on charge until electrolyte temperature is below 35°C.
