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

I had no problem recharging my battery with a standard 12V charger. My E70 is 2012 and I believe the battery is original - still says BMW on it.
For a replacement on my son's E53, I found Costco to be the least cost for an Interstate with a decent warranty - needed to be ordered though. Ended up at the local tractor supply (rural king) for $114 USD out the door. Not sure what the amp-hour ratings were. Never thought to check other than the battery group size and CCAs.
