It's springtime!-

…and time to get those batteries back in shape!

If you have not stored your GEM in a heated, weatherproof environment, and had the battery charger plugged into a timed outlet set to go on once a week for 6 hours, then YOU have work to do!

FIRST- Take your GEM for a ride to run electric through the system. Back up several times to reset brakes, then plug it in and let it take a full charge.

IF—You were unable to get your cart to move, plug it in.
IF—You get a “hi-lo” beep, you have at least one battery that is not taking a charge, and may be bad.


Step 1- Using six colors of electrical tape, 1 for each battery, clean an area on top of the battery with a damp rag and mark the top of each battery with a 2 inch piece of tape, and a ring of the same color around the positive cable of each battery.

Step 2- Remove FIRST the positive cable on all batteries, THEN remove the negative cables on all batteries. AS YOU REMOVE EACH TERMINAL, use a proper battery terminal cleaner on each terminal clamp and each terminal post.

Step 3- Remove each battery, and place in an outside area in a large plastic pan. (IF BATTERIES are CLEAN…move to Step 7)

Step 4- AFTER making sure all cell caps are firmly in place, liberally pour DISTILLED WATER over each battery, making sure to cover the entire top.

Step 5- Using a colander or sieve, liberally sprinkle pure baking soda over the entire top surface of each battery. LET SIT FOR 3 MINUTES.

Step 6- Using DISTILLED WATER, thoroughly rinse the tops of all the batteries. MAKE SURE TO NOT LOSE THE TAPE!!! Thoroughly dry each battery, and move to a bench top in a well ventilated space.

Step 7- ON A BENCH IN A WELL VENTILATED SPACE…Check each battery for damage (ie: cracking, swelling, arc marks. Any damaged battery should be recycled.)

Step 8- Test each battery level on a charger in the “test” mode. Any battery that is not at a full charge, set aside. Any battery with a full charge, return to the GEM car in it’s proper position.

Step 9- If you have any batteries that were not fully charged, separate them into 2 categories.
A- No charge at all
B- Partial charge

Step 10- Take the category A batteries one at a time, and attempt to charge each for 1 hour. If no charge is taking after 1 hour, the battery has failed, and needs to be recycled and replaced. REPLACE ONLY WITH ‘LIKE’ BATTERIES. (ie: match the power and type, such as ‘gel’, ‘lead acid’, etc.)

Step 11- Fully charge all the category B batteries on the mobile battery charger. Check hourly for overheating, leaks or swelling. Any indication of such, should be replaced.

Step 12- Reinstall all the batteries to their appropriate locations, using a proper anti-oxidant conducting gel on each terminal. Wipe any excess across terminal tops, and clean any terminal boots before recapping.

Mark the top of any replacement battery with the purchase/install date using a paint marker.

Proper maintenance of batteries can greatly increase their reliability, performance and longevity.

The first time you use the GEM for the season, you should take a run that nearly exhausts the battery bank. Then, a full overnight charge. Exercising the batteries at the beginning of the season has a tendency to increase your ‘miles per charge’ by up to 15%.

IT’S SPRINGTIME!!!- turn the key and drive!
