Correct Battery for 1970 2002?

[UroTrash]

Does anyone know the factory correct brand/type battery for a 1970 2002 ? Thanks

[ElDiablo]

I have a group size 42, 500CCA @0 degF, 625CCA @32 degF. I bought mine a while back and fits just right in the battery tray. Sorry, but I chose an off brand one.

Any Group 47 will fit with proper terminal position as well. Get an Interstate and remove unneeded decals or spend 160 at the dealer for a BMW white Exide battery.

I have been researching this too. I came up with a Deka # 690MF, which seems to be the best fit and very high performance (600CCA/745CCA @ 32 degrees + 70 month warranty).

Wasn't sure whether the white BMW Exide batteries fit original tray, but these three batteries measure 9-1/2 by 6-3/4 by 7. The 61.21.7.567.182 is 65Ah and the 61.21.7.567.181 is 50Ah--both are wet cell. BMW now carries a glass mat battery 61.21.7.553.952 rated at 70Ah. These batteries are made for the E30 and E36 series and are great for the battery in trunk mod.

The 567.181 is the correct battery, fits coupes and 2002s, 50ah is plenty as it works well for the M30. The 02 battery tray has a small hole on the aft end, it secures a small plastic block that keeps battery secure fore/aft, still available.

After looking at realoem, yes - looks like 2 spacers (p/n 61211350825) are called for. Any images of spacer(s) installed? I just replaced my negative batt cable, and noticed how much space was left for the battery to shift around in the tray. I did secure the hold-down thingy, but it doesn't seem to grab very well onto my battery

sorry i can't help with the spacer question, but nice search dig of the old thread!

$1.06 apiece with CCA discount - I will report back )

installed spacers. They don't really clip into the holes very firmly, and seems like they might rattle and jump out of the battery tray - so I wrapped some electrical tape around the clip-in pieces to make them more secure. Perfect size, though they don't click into place

I took my newly coated battery tray to Costco today to make real sure their Interstate fitment code 27 group124R battery would fit. It was a perfect match as it has very pronounced ridges at the bottom that fit the battery tray and tie-down bar exactly. $97

Every so often we have to re-visit this question. I don't mind.

I'm a purist but I draw the line at batteries and fluids. These are replaced regularily and don't need to be OEM, IMHO.

Any Group 26r is the correct size and configuration. For an early car end grips on the battery are necessary to secure the battery with the original clamp. Not the most secure system. I admit I augmented (defaced  ) my car with a custom clamp. It DOES NOT move.  Safety first.



Group 47 fits but is bigger than necessary (and is very tight in a tii).

Tii and non-tii battery trays are different sizes, and even the hold-downs are at different locations: short end on tii's, long side on non-tii's.

Tii's: Group 26R

Non-tii's: Group 47

agree Paul. And one step further....skip the wet cell batteries altogether. Folks should get agm batteries. They are smaller so it is easier to work around them in engine bay, they can be put out of the way under the rear seat, lighter for better driving, and are sealed so the are no explosive gases or corrosive acids to leak on your nice paint.

Non-tii's: Group 47

 

Really?!  The early tii and the non-tii came equipped with different sized batteries when new?

 

I didn't know that. 

 

I also thought the clamping system changed in 74.
