3 TERM.(UA8) BATTERY SYSTEM CONVERT TO COMMON BATTERY SYS.

MODELS AFFECTED: 1985 ELECTRAS EQUIPPED WITH OPTION UA8

Buick Motor Division has discontinued the optional Power Reserve Battery System which was available on 1985 Electras. Due to the limited number of vehicles produced with this system, and to the possibility of customer inconvenience in obtaining service on this system, the following Special Policy has been established.

Vehicles produced with the Power Reserve System option UA8 will be converted to a more common battery system. This consists of replacing the three (3) terminal posi-power battery with a new two-terminal heavy duty UAl option 78A-72 battery and replacing the power reserve controller and battery cables with new battery cables.

Owners of vehicles involved will be refunded the list price difference of $119 between the price of the two options, plus applicable state and local taxes.

This Special Policy conversion will be done at no charge to the owner regardless of the vehicle age or mileage until June 30, 1986. After June 30, 1986, Buick will continue the refund offer and the conversion of the power reserve system regardless of age or mileage of vehicle at no charge, but the cost of the replacement or new battery will be at the customer expense.

A copy of this "Special Policy Bulletin," should be filed in the 3-ring binder furnished to the dealer by General Motors in September 1982.

Dear Buick Electra Owner.

Buick Motor Division has discontinued the optional Delco Power Reserve Battery System (Option UA8) which was available on early production 1985 Electras.

As part of Buick's continuing commitment to customer satisfaction, we want you to be aware of a serviceability concern that may affect you, since our records indicate you have this battery system on your car.This option can readily be identified by looking at the battery. The battery will have three posts or terminals on top of the battery instead of the more common two-side terminals.

Due to the decision to cancel this option, replacement three-post batteries will not be available. This may cause some customer inconvenience and delays at such time the original battery requires replacement.

To avoid this inconvenience, your Buick Dealer is prepared to convert the power reserve system on your vehicle to the more common battery system. This consists of replacing the three (3) terminal battery with a new two-terminal heavy-duty option UAl 78A-72 battery and new battery cables. If you still own the vehicle, Buick will refund the difference between the manufacturer's suggested retail price of the two options of $119, plus any applicable state and local taxes. To qualify for the $119 refund, the battery conversion must be done to your vehicle, and it must be done by a Buick Dealer. This conversion offer will be done at no charge regardless of the age or mileage on your vehicle until June 30,1986. AfterJune 30, 1986, Buick will continue the refund offer and the free conversion of the power reserve system regardless of age or mileage of vehicle, but the cost of the new battery will be at your expense.

Instructions for making this conversion have been sent to your Buick Dealer. We recommend you contact your dealer to arrange a date to have this service done to your vehicle.

Enclosed with this letter is a request form which is to be used to obtain the $119 refund. After the conversion is done on your vehicle, this form is to be completely filled out by you and the servicing dealer, a copy of Repair Order attached, and mailed to:

We suggest you keep a copy for your records. It will take approximately 30 days for your refund to be processed.

The enclosed owner reply card identifies your vehicle. Presentation of this card to your dealer will assist in making this conversion to your vehicle in the shortest possible time. If you have sold or traded your vehicle, please let us know by completing the postage paid owner reply card and returning it to us.

We are sorry to cause you this inconvenience; however, we have taken this action in the interest of your continued satisfaction with our product.

General Motors bulletins are intended for use by professional technicians, not a "do-it-yourselfer". They are written to inform those technicians of conditions that may occur on some vehicles, or to provide information that could assist in the proper service of a vehicle. Properly trained technicians have the equipment, tools, safety instructions and know-how to do a job properly and safely. If a condition is described, do not assume that the bulletin applies to your vehicle, or that your vehicle will have that condition. See a General Motors dealer servicing your brand of General Motors vehicle for information on whether your vehicle may benefit from the information.
