H8 Everstart from Wal-Mart so through some searching I found

Model No.: MAXX-H8
Shipping Weight (in pounds): 58.0
Product in Inches (L x W x H): 13.9375 x 6.875 x 7.5
Walmart No.: 001072411
• Most powerful EverStart available
• Starting power meets or exceeds manufacturer's specifications
• Great for all-weather climates
• 900 Cold Cranking Amps
• 36-month free replacement warranty

I emailed the company who makes this battery and they informed me that the Amp Hours (AH) is 80 and the Reserve Capacity (RC) is 150.

Old Battery:
01 Battery from Exide (Warranty Only) 110AH 850A 1 61216901815 ENDED
01 Battery from Exide (Warranty Only) 110AH 850A 1 61217591085 ENDED

Cold Cranking Amps (CCA): 850
Reserve Capacity (Min): 110
Battery Length: 394 mm - 15 9/16 in
Battery Width: 175 mm - 6 15/16 in
Battery Height: 190 mm - 7 1/2 in
Post Location: Top Post
Right Or Left Hand Positive: Right
Core Charge Applicable: Yes

So the H8 compared to OEM
H8 CCA 900 AH 80 RC 150

BMW CCA 850 AH 110 RC 110
OEM

Are these reserve capacity and AH rating correct that I found, or did you guys find some different spces throughout your research?

Will this battery even work well for our cars? A

Am I better off returning this battery and getting a Bosch battery from Autozone?

Any input appreciated!!

Thanks
here's the email response I received on Ah:

to me
Bill --

The Walmart Maxx 94R is rated at 765 CCA with 140 minutes reserve capacity. I would estimate the amp hour rating to be 76-80AH (C20).

Best regards,

Ken
