WATERING - MONTHLY
CHECK THE LEVEL IN EVERY CELL AND FILL THE BATTERIES TO THE CORRECT LEVELS
AS REQUIRED. The use of a battery-watering gun
will assist in accurately completing this task. Water should be added, if
needed, after the charging has been completed unless the tops of the
internal plates are exposed. In that case, water should be added before
Be sure that a water suitable for watering batteries (colorless, odorless, tasteless, and suitable for drinking), preferably distilled water, is utilized. If you have any doubt as to the suitability of the water, have it tested and add an appropriate water line filter, if required.
It is most important that all battery cells be filled to the correct level in order to obtain good battery life and minimize corrosion to the electrical system and vehicle.
CLEANING - MONTHLY WASH THE BATTERY TOPS WITH A SOLUTION OF 1/4 CUP (60ML) BAKING SODA TO 1 1/2 GALLONS (6 TO 1) OF CLEAR WATER.
After watering spray the tops and sides of the batteries, the battery wiring and the battery racks with baking soda solution; let the solution stand for at least five minutes to allow the neutralization to take place.
Rinse the entire area with a low- pressure spray of clean water. Do not wash electrical components with direct stream of high pressure water.
If any evidence of corrosion is evident (green powered foam), spray again with baking soda and let the solution stand for at least 5 minutes before rinsing; repeat if required.
Deposits on battery tops must be removed because they are conductive and
cause self-discharge of the battery. Scrub the battery tops with a bristle
brush soaked in baking soda solution. Rinse with clear water.
CHARGING - DAILY RECHARGE THE BATTERIES AFTER USE. Golf car batteries should be charged between rounds if possible.
Before charging batteries, inspect all termination for frayed conductors and loose or damaged connector. Inspect all termination to assure that they are both clean ( corrosion free ) and securely fastened to battery post.
A fully charged battery will not freeze in winter temperatures.
In the "off season" the batteries should be fully charged, disconnected from the charger and stored in an unheated covered area. Check the batteries during the "off Season" at thirty - day intervals, recharge and disconnect charger after charging. DO NOT leave the charger connected to the vehicle during "off season" storage.

car manufacturers have provided in their maintenance and service manuals and
technical training seminars, a basic outline of how lead–acid batteries
function. If you haven’t read your manual or haven’t attended a factory
sponsored training class, you need to do so, as soon as possible.
the most misunderstood aspects of battery maintenance is cold weather
storage. In many areas of the country where extreme cold weather
temperatures prevent winter play, golf cars must be stored until the
following season. In some locations, this can be for up to seven months.
So what needs to be done to prevent the batteries in your golf car fleet
from becoming damaged during long periods of storage? Probably not as much
as you might think.
to what many believe, golf car batteries love cold weather, for storage that
is. I have personally heard stories about golf courses having their
mechanic pull out all the batteries in a fleet, place them on pallets and
move them into a heated storage facility. There, all the chargers were
brought in, each group of six batteries wired together complete with a
charger receptacle, and then charged periodically throughout the remainder
of the winter. Can you imagine the work involved in doing that with an 80
to 100 car fleet? None of this is necessary! Batteries can be stored while
still in their cars and will survive even in subfreezing temperatures if a
few simple rules are followed.
placing any batteries in a storage situation, understand there is a
condition called stand loss discharge (loss of electrolyte specific
gravity) that will affect their life span and survivability.
Batteries, without the benefit of frequent recharging, will rapidly
self-discharge, especially in warm weather. The higher the ambient
temperature, the higher the degree of self-discharge. I have included a
chart (Stand Loss Capacities) that demonstrates the severity of this
situation by showing how quickly batteries stored at various temperatures
can go from a fully charged condition to becoming deeply discharged and
possibly damaged, often permanently. Notice that batteries stored at a
temperature of 42°F (6°C) display much less stand loss discharge than the
other two examples shown at higher temperatures. Even after 19 weeks, the
batteries are at approximately 1.245 specific gravity, well above the
sulfation threshold of 1.220. This means the lower the storage
temperature, the less the batteries will self-discharge. And the
lower the temperature, the better. Even at 0°F (-18°C), batteries will
maintain their charge for an extended period of time. Of course, this is
all predicated on the batteries being clean, in good condition,
and being fully charged prior to being placed into storage.
These conditions are imperative, and they are the keys to
successful winter storage. Unless your fleet is equipped with a
charging system that will automatically turn on and assess battery condition
and perform a periodic “maintenance charge,” I highly recommend you
disconnect the battery pack wiring after the full charge prior to storage if
the chargers are not going to be used. I would also advise you to inspect
the batteries monthly, taking sample specific gravity readings and checking
chargers and circuit breakers if the chargers are to be used during
storage, just to be sure there are no problems.
always concern that batteries will freeze during cold weather storage. They
certainly can and will unless a sufficient charge is maintained. Take note
of the charts listing temperatures at which batteries can freeze (Electrolyte
Freezing Point @ Various States of Charge). As long as the
proper specific gravity (state of charge) is maintained, batteries will not
freeze. If you compare stand loss discharge at the temperature ranges
listed, you’ll see batteries stored at temperatures even well below 0°F
(-18°C) will maintain their state of charge for an extended period as long
as the temperature remains at that level.
See, that wasn’t so difficult, was it? Now when someone asks if your batteries are ready for cold weather, you’ll know the answer
