Correct Battery For 73 2002Tii?


Clint

Recommended Posts

I'm looking for the correct battery for a 73 2002tii

  • Is 55Ah the correct capacity?
  • Is the tii battery slightly smaller in size than the non-tii battery? If so, why?
  • Is there a suitable OPTIMA brand battery? If so, please advise as to part #.
  • Any additional info or recommendation is appreciated.

Thanks.

I've been getting batteries at Walmart because of the warrantee, but Costco is also a good source. I've not tried Optima but I understand they are leak-proof, which is good. You need to be careful about keeping the front terminal away from the bulkhead.

I believe 26R is the correct type of battery.  Available most anywhere.

 

The thing to look for to be correct for all 2002s of that year, is the mounting lip ON THE END.  A lot of 26R batteries only have the lip on the sides.

 

The 73s came with a 2part metal clamp that ONLY fits on the end.  See pic attached.

 

To properly hold down the battery you need this clamp or a makeshift alternative.

That's interesting about the battery clamp--on the carbureted 73s, the clamp is on the side of the battery, facing the alternator.  I knew the battery holder was mounted lower on tii's but didn't know the clamp location was different.

 

Ya learn something new about these cars every day.

Huh.  I guess because the brake booster is larger on the tii, that they altered the box.  I thought all the battery details were the same as well.

 

I ran a larger battery in my car for years before I went back to the 26R.  So much more space with the smaller battery, and with a good or rebuilt starter the smaller battery works just fine.

    BMW Neue Klasse - a birth of a Sports Sedan

    Unveiling of the Neue Klasse Unveiled in 1961, BMW 1500 sedan was a revolutionary concept at the outset of the '60s. No tail fins or chrome fountains. Instead, what you got was understated and elegant, in a modern sense, exciting to drive as nearly any sports car, and yet still comfortable for four.   The elegant little sedan was an instant sensation. In the 1500, BMW not only found the long-term solution to its dire business straits but, more importantly, created an entirely new

    History of the BMW 2002 and the 02 Series

    In 1966, BMW was practically unknown in the US unless you were a touring motorcycle enthusiast or had seen an Isetta given away on a quiz show.  BMW’s sales in the US that year were just 1253 cars.  Then BMW 1600-2 came to America’s shores, tripling US sales to 4564 the following year, boosted by favorable articles in the Buff Books. Car and Driver called it “the best $2500 sedan anywhere.”  Road & Track’s road test was equally enthusiastic.  Then, BMW took a cue from American manufacturers,

    The BMW 2002 Production Run

    BMW 02 series are like the original Volkswagen Beetles in one way (besides both being German classic cars)—throughout their long production, they all essentially look alike—at least to the uninitiated:  small, boxy, rear-wheel drive, two-door sedan.  Aficionados know better.   Not only were there three other body styles—none, unfortunately, exported to the US—but there were some significant visual and mechanical changes over their eleven-year production run.   I’ve extracted t
