Replacing 105AH battery

Does anyone have any luck finding aftermarket battery that is 105AH? All the ones I see online are 92AH. Even the indy shops, which mark up the batterys by a large amount ($200-300) are only 92AH. I'd like to stay with 105AH, which is what the current battery is.

East Penn's 95R/H9 battery has that AH...but you'll need to measure your battery compartment because the H9 battery is longer than the 49/H8 battery size.

You can see what the measurements for the 95R/H9 AGM battery is...if it will fit...I know that Batteries Plus sells that battery under the Duracell name:

I checked with an auto shop and they said E70 is either size 48 or 49 so I'm thinking that the 95R probably won't fit. Has anyone successfully installed a 95R in a E70?

99% of the 49/H8 batteries will have a 90-92 AH rating...the specs within a battery class size is pretty similar among the major 3 battery manufactures (who make most of the battery brands in the USA).

The BMW branded battery is specifically designed to be a 105 AH battery...so that's one spec the dealer branded battery has over the others. If you don't have heavy electrical needs more than normal...a 49/H8 battery would probably be fine. I wouldn't go as low as a 48/H6 battery...as you can see in the chart above that it only rated as 70 AH. That's a lot lower than 105 AH of the original...where as the H8 comes in only a bit lower with 92 AH.

Why not just measure your battery compartment to see if it can take the 15" length of the 95R battery...which is only approx 1" longer than 49/H8. The height & width of the H8 & H9 are the same...its just the length that is different (battery case size wise).

From the chart above...H8 & H9 refers to the battery's (DIN) size. Take note that each battery class has a DIN...then look at the lengthspecs on the right side of the chart and note how the size changes.

Similar to in-dash radios...there are single and double DIN openings...double DIN is twice the size as a single DIN.

And in the back of my head...DIN was some German acronym that represented the opening size in the dash...but the actual meaning of the acronym escapes me at this point.

BTW...I went looking for images of the e70 X5's battery compartment...and I can't find anything that shows a close enough image to see if there's room for a longer battery once you remove the cover.

In the e53 X5...the H9 won't fit...the compartment is not quite long enough...but my e38 & e39 had no issue with either the H8 or H9 battery's length...there was room to accommodate either size...in fact there were 3 battery hold down locations.

{e38 battery compartment - you can see an additional battery hold down hole to the right of the battery which can accomodate an H8 or H9 battery}


{e53 battery compartment - no room for an H9}



When you remove the battery cover on the e70...is there an additional battery hold down location? Is there room for a longer battery even when the cover is put back? (hopefully your fellow e70 X5 owners will chime in)

{e70}

Bosch S6015 105AH 950
Do not forget...this is gel battery!!! I still have Bosch from factory and it is 10 years old! I was trying to recharge it like an idiot of course you can not recharge with ordinary recharger I was thinking why it shows all the te 0% may be it is recharging but it is impossible to see percents! As far as I know they are recharged by impulses

How do I know if the Bosch will fit? Is it a 95R or a 49?
I called BMW and they don't know what size and they said they only have one 105AH size.
