Deep Cycle Battery San Diego Offers Multiple Brands of Lithium, Wet Cell and GEL Deep Cycle Batteries for GEM Car
Early model GEM Cars where fitted with with wet cell, or flooded type deep cycle batteries that need to be inspected monthly to add distilled water.
Later, around 2005 GEM opted for the deep cycle GEL battery chemistry that is maintenance free.
GEL GEM Car batteries are liquid free, survive deeper discharging and do not produce the corrosion traditional GEM Car batteries do.
Lithium batteries are lighter, charge quicker and have a longer life than lead acid if not abused.
A GEM Car is a low speed vehicle that is battery-electric and street legal in nearly all 50 states on public roads posted at 35 mph (56 km/h) or less. With a top speed of 25 mph (40 km/h) GEM cars have a range of up to 30 miles (48 km) on a full battery charge. They are powered by six, 12 volt deep cycle batteries connected together in series to achieve a 72-volt battery system. Recharging the six batteries at once happens by plugging into a standard 110-volt outlet for six to eight hours. There are currently six different models of GEM cars on the road today. GEM cars are used by local, state and national government agencies, resorts, master-planned communities, universities, medical and corporate campuses, as well as by sports teams, taxi-shuttle services and individual consumers. There has been over 45,000 GEM Car’s produced since 1998.

Battery Best Practice Tips for GEM Car:
1. Use a dedicated outlet to charge your Gem Car. If you use a shared outlet, good chance the charger will stop charging when another appliance starts up.
2. Use a heavy gauge (12) electrical cord 25′ or less.
3. Charge frequently for as long as the batteries require. The on-board charger will shut off when fully charged.
4. Use the master disconnect switch to turn off power consumption from batteries when not charging or driving. This rule applies to lead acid and lithium batteries.
5. Replace the OEM charger with a QuickCharge on-board charger for lead acid when possible.
6. Do Not Trust the little green light on steering column.
7. Use a battery hydrometer to test flooded style batteries monthly for health and state of charge vs the little green light.
Early model GEM Cars use wet cell or flooded type batteries, while the later models switched to GEL type batteries. Gel type of deep cycle batteries will power the GEM Car, but for charging, the on-board charger must have the correct charging algorithm selected.

What is the difference between AGM batteries and Gel batteries”
Gel batteries contain a gelled electrolyte which is “Thixotropic”. This Thixotropic gelled electrolyte contains sulfuric acid, fumed silica, pure demineralized and deionized water and a phosphoric acid. The electrolyte in Gel batteries does not flow like a normal liquid; it has the consistency and look of petroleum jelly.
Absorbed Glass Mat Batteries – AGM
In AGM batteries, the liquid electrolyte contains high purity sulfuric acid and totally demineralized, deionized water (no phosphoric acid). This electrolyte is trapped in sponge-like glass mat separators.
