GEM Car Battery

GEM Car Battery Replacement San Diego

A GEM Car battery is a 12 Volt deep cycle battery that is designed for the deep discharging and recharging cycles that a GEM Car requires.  Inexpensive marine batteries from Costco will not survive more than a few months under normal driving conditions. Only a 12 Volt battery group size 30 or 31 with 100 or more amp hours should be used. Battery group sizes 24 and 27 are too small and do not have the capacity to continuously operate the GEM Car.

The 12 Volt deep cycle battery is available in flooded (often called wet cell or standard lead acid) AGM or GEL cell batteries.  AGM type batteries must be the high cycle type and not UPS type for the GEM Car.

  • Flooded are least expensive and require monthly maintenance
  • Only AGM (absorbed glass mat) batteries by Leoch or Trojan Overdrive should be used!
  • GEL cell batteries are liquid free and do not require maintenance but are the most expensive
  • A flooded GEM Car battery will gas and cause corrosion like standard flooded battery
  • The GEM Car’s on board charger must be set to charge the type of battery that is installed
  • It is advised to replace the factory Zivan or Delta Q charger with the Quick Charge charger for better battery results

GEM Car Battery San DiegoExample, a GEM Car that has 12 Volt GEL Deep Cycle Battery from Deka must have the GEL battery profile selected. Same is true for flooded GEM Car batteries.
You can use a YouTube video guide to help you change the onboard charger profile.
**Note GEL and AGM are Not the same charging profile

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 for GEM Car – 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.

Today’s high cycling AGM batteries are less expensive than gel and maintenance free.  It is necessary to have the correct or best charger for any battery you use.

If you live in a hot climate area like Arizona, GEL chemistry GEM Car batteries will endure the heat better than AGM.

We recommend not using the OE onboard charger when it comes time to replace

Batteries for GEM Car We Do Not Recommend

Based upon field observation and premature failure we do not recommend using any marine or dual purpose deep cycle batteries for the GEM.  Yes they are less expensive but the will not sustain the high cycling demand of the GEM Car.
Interstate AGM batteries are Thin Plate Pure Lead and are great for cranking and some light cycling duty but do not survive the deep cycles from the GEM.

GEM Car Battery Buyers Guide

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 recharging, the on-board charger must have the correct charging algorithm selected.

Questions We Get Asked Daily Regarding GEM Car Battery Maintenance and Charging

 

Q: Which batteries are best for Gem Car?

A: 12V Group 30 or 31 deep cycle batteries

Strong, deep cycle batteries. Not wal-mart, Costco or mid-grade marine/RV deep cycle batteries.

Q: Are sealed deep cycle batteries better for Gem Car?

A: The discussion has many opinions but the decision is based upon if you don’t mind monthly hydration required by flooded cell batteries.  The Crown 31DCHD, Trojan 30XHS, US31DCXC

Are flooded cell type and will consume water when the batteries are recharged.

Typically, the flooded cell type deep cycle batteries have higher amp hours and lifecycles compared to AGM or Gel deep cycle batteries.

 

FYI

1999-2003 GEM Car OE was flooded cell deep cycle batteries – 12V 130 ah

Two batteries in the front hood and four under drivers seat.

2004 and up GEM placed all six batteries are under drivers seat and GEM sourced Deka 8G31 as OE

 

Sealed Battery Choices: Gel & AGM

A Gel deep cycle battery will cost more and should be 12V Group 31 with 98 ah or higher.

Gel batteries work better in hot climates, Arizona etc

 

An AGM deep cycle battery has good lifecycle and is sealed so no watering required.

Do not use UPS style AGM batteries. UPS AGM batteries are less expensive but are not designed to discharge the recharge hundreds of times like deep cycle AGM are.

Examples of good AGM for GEM are Trojan 31 Overdrive, Leoch EV12115  and Crown 12CRV110

 

Q: Where is the GEM Car charger located?

A: Inside the dash next the GE controller

 

Q: Why won’t the batteries stay charged when car is left plugged in?

A: The early model GEM Cars used Zivan and the charger will complete one charge cycle and shut off regardless if left plugged in. Zivan will not maintain the batteries.

The green light will come on telling you charging is complete – Don’t be tricked by the green light.

Unless you unplug and replug in the car to restart the Zivan on-board charger, the battery state of charge rapidly decreased.

After one day, even at rest, the car is no longer 100% charged.

After five days, the car has drained the batteries to 75% state of charge.

 Deficit Charge Syndrome for GEM Car

Undercharged batteries are a major cause of system failures in GEM Cars.

Deficit Charge is a charge cycle in which less charge is returned to a battery bank than what was withdrawn from driving the GEM Car. Deficit charge can occur in situations where AC power supply is poor due to oversharing the 110 AC outlet with the GEM  or if the extension cord is too long and undersized.

If the flooded / AGM or Gel Gem Car batteries experience repeated deficit charge cycles and are left in a partial state of charge for long periods, they will become progressively more difficult to charge and suffer a loss of capacity. When charged, voltage will rise more quickly in batteries with sulfation than in normal batteries, falsely indicating a high state of charge. The Delta Q and Zivan charger will falsely report 100% state of charge when the batteries have not been fully charged. Recovery from this condition can sometimes be accomplished by an equalization charge.
