Has anyone found a UK source for the internal CR1220 PCB battery with the correct pin configuration?
They're also used in the CME BodyGuard.
We're paying nearly £12 each for the "official" ones, but the only ones I can seem to find by a third-party (eg: RS @ £1.08) requires a little tweaking and risks shorting the pins!

Any help to save a little would be much appreciated.
Regards,
Andrew.

Do you have any picture(s) for us, Andrew? think

Which one? ... eBay? Amazon?

Otherwise ... at those rates surely you can risk a little "tweaking"? smile

Hi, had the same issues here. The part you are looking for is the CR-1220/FCN, the leg configuration on the Farnell one is VCN and needs bending but some consider it a "modification" so will not approve it.

I have found some in Europe but I am currently trying to get a friendly battery supplier in the UK to give me details and prices, If they can do it I have asked them to post on here, if they are not allowed as it is "advertising" then I will.

The price mark up on these batteries is obscene, I have sourced them in the US at just over a dollar but they will not air freight. Alibaba do them for 7 cents US with 50 as a min order, but not sure about shipping from China.

I will keep you posted on my efforts.

Everyone should remember that all medical devices need to meet the strict requirements of the medical device directive (now medical device regulations). If you fit a part that is not sourced from the OEM or failed to fit an OEM part in accordance with their instructions, you have effectively made a modification to the device and invalidated the CE marking. All liability for the device has now passed to you!

If your cheap Chinese import battery burst into flames or causes the pump to malfunction I hope you have good legal cover!

I wonder where the OEM gets them from? think

The OEM will obtain them from either the manufacturer or their approved supplier, who will be ISO certified with full traceability. The OEM may also do their own quality control tests and checks before use. If there was a recal or other fault found the OEM would issue a field safety notice to be able to rectify the issue.

This is what is required by the medical device directive and is one of the reasons medical spare parts cost more than off the shelf parts. Most OEM follow ISO 13485 Medical devices – Quality management systems – Requirements for regulatory purposes. How many of those repairing medical devices follow this?

MikeX, you are saying that all the batteries sold by Medgraphics and Euroenergy, and fitted by lots of us, are a modification when they are identical in form, fit and function? The lamps I get from hospital lamps supplies are non OEM, is that a modification too?
Some bits I can understand the reasoning, but these batteries are all made in the same factories, the OEM sources them from the same sources as the battery suppliers we use, they all have ISO certification and the requisite traceability, it is not as if they are buying off the "grey" market.
The argument you use sounds like a manufacturer trying to justify monopoly pricing at gouge levels.

Mithrandir - Thanks for the EuroEnergy info. I can't find any reference to that part number on their website, or in any lists that we have though!
Is it a new part that you have managed to get them to source for you? Do you have a price?
Regards.
