Battery Hydrometer Deep Cycle (Plastic)
Hydrometers are used to determine the Specific Gravity of
the electrolyte (acid) in wet cell batteries. This allows you to determine
State of Charge (SOC) and to compare cells to determine straying voltage in
cells before equalization.
- Full Size Hydrometer Battery Tester
- Larger Print Easier To Read
- Plastic Construction For Commercial Applications
- Professional Quality For Highest Accuracy
- Precision Graduated Specific Gravity Float
While most folks don"t understand the proper test procedure
for testing Specific Gravity to determine State of Charge (SOC) all is not
The real useful way to utilize the hydrometer is to do
your cell to cell check to determine when you need to equalize (overcharge) your battery bank. Because
youre not determining SOC, just difference, there"s no need to fool with temperature
compensation, as the conditions will be the same for all the cells.
When the difference from the highest cell to the lowest
exceeds .15 on the hydrometer you need to bring the cells back to equal again
by overcharging (equalization). Don"t
forget to check after the EQ to make sure you did in fact, bring the cells back to equal.
It will do you well to remember that this liquid is H2SO4 (sulfuric acid) and it"s very
dangerous. Eye, face and body protection is an essential must.
