Battery Specific Gravity Chart. This may be done under load but care must be taken and it is never recommended if the truck is in service. The table assumes that a 1.265 specific gravity reading is for a fully.
1.250 specific gravity discharge rates (kw per cell*) to 1.67vpc at 77°f (25°c)** battery type minutes So the sg of water = 1.000. • you will often see this rating across many kinds of batteries, not just starters, and frequently, this is quite a marketable feature of many modern battery.
Materials With A Sg>1 Will Sink In Water;
The hydrometer is calibrated if it agrees with the sample within its manufacturing tolerance. Measuring and monitoring sg is critical to maintaining fla batteries and maximizing their service life. So the sg of water = 1.000.
Typical Specific Gravities For Certain Applications Are Shown In Table 1.
The higher the dod, the lower the cycle life.

Materials With Sg <1 Will Float.
1.250 specific gravity discharge rates (kw per cell*) to 1.67vpc at 77°f (25°c)** battery type minutes For temperature adjustments, get a specific. The actual operating life of the battery is affected by the rate and depth of cycles and by other conditions such as temperature and humidity.
If Any Specific Gravity Readings Register Low, Then Follow The Steps Below.
Acid specific gravity and charge level in a lead acid battery: The table assumes that a 1.265 specific gravity reading is for a fully. • you will often see this rating across many kinds of batteries, not just starters, and frequently, this is quite a marketable feature of many modern battery.

The purpose of this specification sheet is to assist in the selection of batteries. Cycle life is estimated for specific charge and discharge conditions. The specific gravity of the electrolyte in a fully charged cell should be from 1.280 to 1.300.
