Lead Acid Battery Specific Gravity Tester

Mighty max battery golf cart deep cycle battery hydrometer tester brand product.

Lead acid battery specific gravity tester.

This item deluxe hydrometer battery tester test specific gravity fluid lead acid batteries. Simply insert the nozzle into the battery and depress the finger pump which draws a few drops of sulfuric acid h2so4 through the tube. Specific gravity testing is easy and efficient with the sbs 2003. The above equations permit electrical monitoring of approximate specific gravity on an occasional basis.

Specific gravity tester for lead acid batteries. Cell open circuit voltage specific gravity 0 845. If you re testing an automobile battery take the vehicle for a 20 minute drive then shut off the engine for 4 hours for other types of lead acid batteries charge them all the way before letting them rest for 4 hours. 4 4 out of 5 stars 51.

You can measure the specific gravity using a hydrometer if you have flooded lead acid batteries ones with caps on top that you can remove to get at the liquid electrolyte inside. Here is how it works. While it takes a bit of time this process of charging and then resting the battery gives you the most accurate. Performance tool w1657c deluxe battery tester.

As mentioned earlier specific gravity measurements cannot be taken on sealed lead acid batteries. Otc 4619 professional battery hydrometer. This solution consists of 65 water and 35 sulfuric acid. 3 7 out of 5 stars 9.

When the lead acid battery accepts charge the sulfuric acid gets heavier causing the specific gravity sg to increase. The hydrometer offers an alternative to measuring soc of flooded lead acid batteries. Charge the battery fully then let it rest for 4 hours. The lead acid battery used in today s automobile is made of plates lead lead oxide in a solution of electrolyte.

Then look up the specific gravity in the following table to find the depth of discharge dod of the battery s cell that you took the electrolyte from. Deluxe hydrometer battery tester test specific gravity fluid lead acid batteries. The specific gravity or weight of this solution increases as the battery charges and decreases as the battery discharges.
