Lead Acid Battery Specific Gravity Tester

Performance tool w1657c deluxe battery tester.

Lead acid battery specific gravity tester.

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. The above equations permit electrical monitoring of approximate specific gravity on an occasional basis. Mighty max battery car battery test hydrometer tester lead acid battery brand product. Charge the battery fully then let it rest for 4 hours.

Ezred sp101 battery hydrometer. As mentioned earlier specific gravity measurements cannot be taken on sealed lead acid batteries. 4 4 out of 5 stars 51. Otc 4619 professional battery hydrometer.

When the lead acid battery accepts charge the sulfuric acid gets heavier causing the specific gravity sg to increase. While it takes a bit of time this process of charging and then resting the battery gives you the most accurate. The specific gravity or weight of this solution increases as the battery charges and decreases as the battery discharges. This solution consists of 65 water and 35 sulfuric acid.

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. 3 7 out of 5 stars 9. Cell open circuit voltage specific gravity 0 845. Specific gravity tester for 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. Here is how it works. 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. The lead acid battery used in today s automobile is made of plates lead lead oxide in a solution of electrolyte.

Deluxe hydrometer battery tester test specific gravity fluid lead acid batteries. The lead acid battery was invented in 1859 by french physicist gaston planté and is the earliest type of rechargeable battery despite having a very low energy to weight ratio and a low energy to volume ratio its ability to supply high surge currents means that the cells have a relatively large power to weight ratio these features along with their low cost make them attractive for use in. The hydrometer offers an alternative to measuring soc of flooded lead acid batteries.
