Pontiac battery replacement in Al Taawun

BCI group numbers describe the case dimensions and terminal layout. Groups 47, 48, 94R and 49 are the same cases as European H5, H6, H7 and H8, and are used on most modern Pontiac cars and SUVs, covering roughly 60 to 95 Ah. Group 65 is common on older Ford-family trucks and SUVs, groups 34 and 78 on older GM and Chrysler-family models, with side terminals on some. Mixing up top-post and side-post types is the usual mistake. The technician reads the group number from the label on your battery.

Under the bonnet is the usual place, though American makers have used some unusual spots: under the rear seat, beneath the front passenger floor, in the boot, and even behind a front wheel arch liner on certain older models. If your Pontiac is one of these, the car has remote jump terminals in the engine bay. Full-size SUVs and pickups sit high, so in a basement with low pipework the technician works from a step at the front and needs the bonnet to open fully.

Full-size American SUVs and pickups are awkward in Al Taawun's street bays, so a Pontiac usually ends up in the basement or on a podium level, and sometimes outside when the height bar is too low. Left in the open, a dark bonnet soaks up the sun for hours and the battery bakes with the rest of the engine bay. Remote start, used to cool the cabin before the walk down from the flat, also takes a heavy draw each time. A yearly test catches the decline before the vehicle refuses to crank.
