Can I purchase a new battery for an MR1100

I've been trying to find a replacement battery on Amazon with no luck. It appears that not all W-10a batteries will work. My Oem battery has a part number of 308-10080-01 and I couldn't find that part number anywhere on the internet. Given I read a post from a supposed expert on Amazon that as long as it's a w-10 or W-10a it will work even if the part number is different. I bought a W-10a (p/n 308-10034-01) but when I installed it I got an error code 3 (whatever that means) and a prompt to remove the battery and USB connection, which I did. Upon reinstalling I got the se message. I sent the battery back as defective and received a replacement. Same problem. Has anyone experienced the same problem and if so how did you fix it?
