How to Check Battery Charge - Introduction and Charging

Aug 04, 2022   Pageview:41

As golf cart batteries sustain some wear and tear and begin to age, their lifespan begins to shorten. The maximum output voltage and amperage of the battery may also decrease, making it less effective. Battery rejuvenation may restore most of its power while also managing to keep it healthy.

How to Check Battery Charge?

You can try the following steps:

An easy approach to test golf cart batteries is to use a handy voltmeter. With the motor turned off, access the battery. In this case, the voltmeter will still display a reading.

Connect the voltmeter's negative probe to the ground or negative terminal of the battery. Repeat the process on the other side.

On a voltmeter, healthy batteries should read 50 to 52 volts. Most battery packs have a voltage of roughly 48 volts.

You must note that a high voltage reading does not imply that the batteries are 100% functional. This recorded figure does not account for the load or the cart's power usage.

A voltmeter is wonderful to begin with. You must replace your fully charged batteries if they show less than 48 or 50 volts.

How Do You Fix a Dead Cell in Golf Cart Batteries That Are Bad?

These are some steps for repair if you find some problems with your golf cart's batteries:

Step 1: Remove the battery from the compartment.

Golf cart batteries are often located beneath the front seat, and thus, the front seat must be removed from the cart. The front seat on certain cart types is movable and may be pulled straight up.

Step 2: Remove Corrosion from the battery.

Mix 2 tsp baking soda with 1 quart of water, while wearing gloves and eye-goggles for safety. Dip a paintbrush into the solution and generously apply it to any areas of corrosion on the battery, particularly on the battery connections and the surrounding regions. Where the baking soda and battery acid contact each other, expect the solution to bubble and fizz.

Step 3: Wash the batteries with paintbrush dipped in water.

Use normal water to wipe all of your battery surfaces until all corrosion has been removed.

Step 4: Examine the Battery.

Examine the battery for fractures or other flaws. Remove any batteries with damaged cases and replace them, especially if the battery acid seems to be leaking into the battery compartment.

Step 5: Take Off the Plastic Caps.

Take off the caps that cover the battery cells. To remove the caps, you may need to slip the end of a slot screwdriver under the cell cap and pry upward. Check each battery cell and make use of a turkey baster for adding distilled water to any cell with exposed plates. Pour enough water to cover all of the plates.

Step 6: Get the Battery charged.

Have the battery charged overnight with a three-phase charger configured to charge 6-volt cells. Some chargers need you to manually set the charging voltage between 2.3 and 2.35 volts. 

Connect the positive (red) wire to the battery's positive (+) pole and the negative (black) wire to the battery's negative (-) pole. 

After connecting the charger to the battery, plug it in and turn it on.

Step 7: Inspect the Charge.

Check the charge in the morning after overnight charging. If the battery charger shows that the battery has been fully charged, examine the cells and add extra distilled water to any cells with exposed battery plates.

After that, reinstall the cell caps. However, if the charger does not show that the battery has been fully charged, you must take further precautions (see Step 8).

Step 8: Drain the Battery Acid.

Allow roughly half of the battery acid to flow out of each cell and into a plastic container by tipping the battery on its edge. 

As mentioned in Step 2, clean the battery with a paintbrush soaked in a baking soda solution. 

Use simple water to rinse your batteries, making sure no water goes into the cells.

Step 9: Pour fresh mixture.

Combine 2 quarts warm distilled water and 8 ounces Epsom salt. Stir them together well. 

Fill each battery cell with the Epsom salts solution with the help of your turkey baster, until completely coated.

Step 10: Get the battery charged.

As instructed in Step 6, charge the battery again overnight. The Epsom salts should dissolve the battery plate deposits that were previously preventing full charging of the battery. In the morning, check the battery. If the battery does not charge completely even then, it is unlikely that it can be rejuvenated. Replace the cell caps and operate your cart normally if the battery has been charged. Every night, use a trickle charger in order to keep the batteries in top condition. 

How Do You Rejuvenate Dead Golf Cart Batteries?

You need:

Turkey baster

baking soda

Epsom salts

Gloves

Safety goggles 

Toothbrush

Battery charger

Distilled water

Directions:

After donning safety goggles and gloves, open the top of the cart battery and drain approximately 50% of the battery acid from each battery cell.

By removing the acid, you can work in the battery without risk of injury. It is also required because you have to pour a cleaning solution into the cells.

To break up the crystals, the interior of the battery must be cleansed with water and a toothbrush. Clean the battery plates with more focus, as here is where the most of the damage is likely to occur.

In a large mixing basin, combine eight ounces of Epsom salts with two quarts of water and suck up a tiny bit with the turkey baster.

Fill the cells with Epsom salt water until they are completely full. This salt combination is intended to remove any deposits or crystals on the plates' sides as well as replenish the acid in the battery cells.

After you have finished cleaning the battery, connect it to a charger and charge it completely. The rejuvenation procedure will fail if the battery refuses to charge to 100% once more. However, if the battery charges back again fully, shut the covers and replace the battery on the cart. To eliminate any residue from the cleaning procedure, wipe off the battery's surface.

If the rejuvenation was effective, the battery should live almost as long as it did when it was new. Ride the cart for a few hours to observe how well the recharged battery holds a full charge.
