Visual inspection alone is not enough to accurately assess the overall condition of a battery.
Both open-circuit voltage and specific gravity measurements provide valuable insights into the battery’s charge level, age, and health. Regular voltage and gravity tests not only indicate the state of charge but also help identify issues such as undercharging, overwatering, or even detecting a weak or faulty battery. The steps below detail how to correctly perform routine voltage and specific gravity tests on batteries.
I. Specific Gravity Test (for Flooded Batteries Only)
• Do not add water at this time.
• Fill and empty the hydrometer 2 to 4 times before taking a sample.
• Ensure the hydrometer has enough electrolyte to fully support the float.
• Take a reading, record it, and return the electrolyte to the cell.
• Repeat the above steps for each cell in the battery.
• Replace the vent caps and clean up any spilled electrolyte.
• At full charge the Gravity has to be 1240 -1250.
If any specific gravity readings are low, follow these steps:
• Check and record the voltage level(s).
• Fully charge the battery.
• Take the specific gravity readings again.
• If readings are still low, perform an equalization charge (refer to the Equalizing section for the proper procedure).
Take the specific gravity readings once more.
If any readings remain below 1240-1250 gravity, one or more of the following conditions may exist:
• The battery is nearing the end of its life.
• The battery has been in a discharged state for too long.
• Electrolyte has been lost due to spillage or overflow.
• A weak or bad cell is forming.
• The battery was overwatered before testing.
II. Open-Circuit Voltage Test
For accurate voltage readings, batteries must remain idle (no charging or discharging) for at least 6 hours, preferably 24 hours.
• Disconnect all loads from the batteries.
• Measure the voltage using a DC voltmeter.
• Check the state of charge using Table 1 below.
• Charge the battery if it shows a charge level between 0% and 70%.
Steps to Check Voltage with a Multimeter:
• Set the multimeter to DC Voltage (20V setting). This setting is appropriate if you are testing 6V, 8V, or 12V batteries.
• Connect the positive terminal of the battery to the positive probe of the multimeter (red color).
• Connect the negative terminal of the battery to the negative probe of the multimeter (black color).
• Read the voltage displayed on the multimeter screen.
If the battery registers below the values in Table 1, the following conditions may exist:
• The battery has been in a discharged state for too long.
• The battery has a bad cell.
Batteries in these conditions should be taken to a specialist for further evaluation or retired from service.

General Watering Instructions
• Add water, never acid, to the battery cells. (Distilled water is recommended)
• Do Not Overwater
• Fill the water, leaving a 1.5 mm gap at the top after the terminal is open.
• If the batteries are discharged, only add water if the plates are exposed. Add just enough water to cover the plates, then charge the batteries. Once fully charged, add water to the appropriate level as indicated above.
• After watering, make sure to secure the vent caps on the batteries.
Step-By-Step Watering Procedure
• Open the vent caps and inspect the fill wells.
• Check the electrolyte level; it should be at the top of the plates as a minimum.
• If needed, add just enough water to cover the plates at this stage.Fill the water, leaving a 1.5 mm gap at the top after the terminal is open.
• Fully charge the batteries before adding any more water (refer to the Charging section).
• After charging is complete, open the vent caps and recheck the fill wells.
• Clean, replace, and securely tighten all vent caps.
Important Things to Remember
• Do not let the plates be exposed to air, as this can damage (corrode) them.
• Avoid filling the water level in the fill well up to the cap, as this can cause the battery to overflow with acid, leading to capacity loss and a corrosive mess.
• Use only distilled or deionized water; do not use water with high mineral content.
CAUTION: The electrolyte is a mixture of acid and water, so avoid skin contact.
WARNING: Never add acid to a battery.
Batteries can collect dust, dirt, and grime. Keeping them clean helps in identifying potential issues early and prevents problems caused by buildup.
• Ensure all vent caps are securely in place.
• Clean the battery top with a cloth or brush and a mixture of baking soda and water. Avoid letting any cleaning solution or foreign material enter the battery.
• Rinse with water and dry with a clean cloth.
• Use a post and clamp cleaner to clean the battery terminals and the inside of cable clamps. Properly cleaned terminals will have a bright metallic appearance.
• Reconnect the clamps to the terminals and apply a thin coat of anti-corrosive spray or silicon gel.
• Keep the area around the batteries clean and dry.
Lead-acid batteries can be significantly affected by periods of inactivity. Follow these guidelines to ensure the battery remains in good condition and ready for use.
Note: Storing, charging, or operating batteries on concrete surfaces is completely acceptable.
Key Things to Avoid
• Freezing: Avoid storing batteries in locations where freezing temperatures are expected. Maintain a high state of charge to prevent freezing, which can cause irreparable damage to the battery’s plates and container.
• Heat: Keep batteries away from direct heat sources like radiators or space heaters. Temperatures above 80° F (26.6º C) can accelerate self-discharge.
Step-By-Step Storage Procedure
• Fully charge the battery before storing it.
• Store the battery in a cool, dry place, protected from environmental conditions.
• During storage, monitor the specific gravity (for flooded batteries) or voltage. Provide a boost charge if the battery shows 70% charge or less.
• Fully charge the battery before reactivating it.
• For optimal performance, equalize the batteries (for flooded types) before returning them to service. Refer to the Equalizing section for instructions.
Proper battery charging involves applying the correct amount of current at the right voltage. Most chargers automatically regulate these parameters, though some allow for manual adjustments. Both types of equipment can present challenges. Consult Tables 2 & 3 for the necessary voltage settings for programming your charger, and always refer to the manufacturer's instructions for proper use. Here are some key tips for charging:
• Familiarize yourself with and follow the manufacturer's instructions for the charger.
• Charge batteries after each period of use.
• Lead-acid batteries do not develop a memory effect and do not need to be fully discharged before recharging.
• Charge batteries in well-ventilated areas, away from sparks or flames.
• Ensure charger voltage settings are correct (refer to Table 1).
• Check the water level (refer to the Watering section).
• Tighten all vent caps before starting the charge.
• Avoid overcharging, as it causes excessive gassing (breakdown of water), heat buildup, and battery aging.
• Avoid undercharging, as it leads to stratification and can cause premature battery failure.
• Do not charge a frozen battery.
• Avoid charging at temperatures above 120°F (48.8°C).
• At full charge for 48 V system, voltage should be 50.5 V.
The way batteries are discharged depends on your specific application. However, here are some general guidelines:
• Shallow discharges can extend the battery's lifespan.
• Aim to discharge batteries to 50% or less.
• An 80% discharge is the maximum safe level.
• Avoid fully discharging flooded batteries (more than 80%), as this can damage or destroy the battery.
• Experts often recommend operating batteries within the 50% to 85% charge range. If following this practice, periodic equalization charging is essential.
• Do not leave batteries deeply discharged for extended periods.
• Lead-acid batteries do not develop a memory effect and do not need to be fully discharged before recharging.
• Charge batteries after each period of use.
• If a battery charges but cannot support a load, it is likely defective and should be tested. Refer to the Testing section for the proper procedure.
Common Mistakes Made by Flooded Battery Owners
• Undercharging: Regularly operating the battery in a partial charge state or storing it in a discharged condition can lead to the buildup of lead sulfate on the plates (sulfation). This reduces performance and may cause premature failure. Undercharging also leads to stratification, where sulfuric acid accumulates at the bottom of the battery, exacerbating lead sulfate buildup.
• Overcharging: Continuous overcharging accelerates the corrosion of positive plates, increases water consumption, and can create damaging temperatures in the battery.
• Under-Watering: Water loss occurs during charging in flooded batteries. If the electrolyte level falls below the top of the plates, it can cause irreversible damage. Routine checks and maintenance of water levels are essential.
• Over-Watering: Excessive watering dilutes the electrolyte, which diminishes battery performance. Adding water before charging can also cause electrolyte overflow and increase maintenance needs.
