EBME Forums Forums Maintenance Technical Assistance BBraun Space batteries rebuild

Hello mates,

I'd like to know your opinion for a rebuilding of old Space batteries by a local battery manufacturer. The sales representative visited us and made 5x cheaper offer.

Are there any big risks? Do you have an expirience?



Thank you for response!

Be careful that the cells are good quality ones. I bought a copy (cheap) laptop battery from ebay (China )and the cells had little capacity even when new. Also the batteries are intelligent so make sure that all that circuitry still works.
How about getting one made up and put it through some tests in the workshop before committing yourself

Thank you Robert,
the functionality is one thing.

In fact, I mean the matter of legislative. The battery wouldn't be genuine, if something bad happened. B.Braun could say: The patient died because the battery in that pump was not compatible (modified, rebuild...) and the pump didn't work properly.

Or not?

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.

Bravo! Robert, Bravo!

I find the BBraun batteries to be fairly unreliable anyway.

I would doubt the the quality of battery makes any difference, the management circuit in them is "so" intelligent it will mess up any way.

In theory, a good battery should be fine in here, the on board circuitry should callibrate to it ok.

Lets us know how a sample one goes, they are only NiMH cells.
