EBME Forums Forums Maintenance Technical Assistance CSB batteries and Plum 360 Pumps FSN

Hi,

There's a new FSN for ICU Medical Plum 360 infusion pumps. See attachment.
It relates to batteries manufactured by CSB, Type GP 645 prior to Jan 2023.

• CSB replacement batteries for the Plum 360 manufactured before January 1, 2023
• New Plum 360 pumps built with CSB batteries manufactured before January 1, 2023

I thought it might be of interest if you haven't already heard.

I would also be interested in what the fault with the battery is?
We know the symptom from the FSN.
I know that prior to CSB batteries being fitted, Panasonic LC-R064R5P were used, however I am lead to believe that Panasonic no longer manufacture this battery.

Confusingly, although the LC-R064R5P is still listed on various suppliers' websites, other sites say it has been discontinued.

Some sites offer "equivalents", so one would have thought that the supplier for the pumps could (should) have recommended a valid substitute. These are simply sealed lead-acid batteries, after all.

As for CSB batteries ... it seems they are manufactured all over Southeast Asia (seemingly Vietnam in this case); so I wouldn't be surprised if quality may be "variable".

GP 645

Plum 360 manual ... lots of stuff about the battery in there.

From the FSN (item 13):-

"To date, ICU Medical has received one report of an adverse event potentially related to this issue".

(italics added are mine)

I am being told the problem with the batteries was one of the internal connection wasn't reaching the desired temperature. I take this to mean there is an internal "dry joint" (the name I use for a solder connection which has failed to flow or with time creates a circular gap around the wire.) ICU are replacing CSB batteries they have supplied. We also bought from Euro Energy but I have not heard if there is going to be some replacement scheme.

Yes; that's not a bad description of a dry joint.

Free replacement of defective batteries sounds fair enough to me.

Has anyone heard of any more "potential" adverse incidents surrounding this issue?

I've had a number of these batteries fitted to my plum pumps since October 22 and after approximately 6 weeks of use there is a message on the pump 'service pump / replace battery'. We are awaiting new batteries to replace all the affected pumps.

How is everyone doing with these now?
I had a delivery of batteries in June, lot starting 23..... and they are failing. Unfortunately this coincided with a software upgrade, so the waters are muddied as to whether it is the batteries or the software.....
I am awaiting a new battery delivery /replacements from ICU

How is every one doing with these Plum batteries?
We are still getting pumps back on a regular basis and it's becoming unsustainable, with no resolution in sight yet :-(
