Even if you used a BBraun battery and the equipment malfunctioned, unless you had a very special arrangement, I doubt if the manufacturer would take any responsibility. Once you have purchased something it is yours and hence your responsibility.
The law in this country is concerned with negligence. If you have thought about something and have risk assessed it and have come to a decision and been sensible about this you are not negligent.
In this country it is common practice to purchase batteries from an alternative specialist battery supplier and they often offer a recelling service as well for OEM batteries.

There are those who argue that we must only buy original equipment and must only do what the manufacturer tells them. I am not one of those. I am employed to think as well as to do.
