2008 Jeep Wrangler Owner Comments

problem #1

Aug 202008

Wrangler Limited 2.8L

  • Automatic transmission
  • 54,059 miles

A D V E R T I S E M E N T S

I am up to Battery 3 in this Jeep from new the battery is an Optima D31A the only battery that will fit.

This battery is AGM (absorption Glass Matt)which requires a charge of 14.4 Volts the Jeep voltage regulator puts out 13.6 Volts so the battery will never recover and will fail over a short life.

The problem is known and not been resolved.

The regulator has to be changes in the Alternater to resolve the issue or the fiting of a Sterling Power Alternator Regulator Pro Reg B to the Jeep to correctly charge and condition the battery to last.
