EBME Forums Forums Maintenance Technical Assistance Hewlett Packard Viridia M3 - problem with new accu

I've found a guy which is able to reprogramm this battery. But I don't have a clue which values were in original battery.
...I'm still assuming that problem is in "incompatible" values stored in Smart electronics of battery pack

Sounds like a useful guy.

Meanwhile, have you tried making enquiries on that other well-known forum?

No, i haven't, but i think it's a good idea

Does anyone know the difference between NJ1020 and NJ1020HP?

NJ-1020 versus NJ-1020-HP.

The NJ-1020-HP Data Sheet says "compatible with Phillips M-3046A M3/M4 patient monitors". Perhaps detailed comparison of the Technical Data Sheets might yield hidden secrets (but I've just spent five minutes with them and didn't spot any differences). Could the difference be the one that appears on the price list?

Meanwhile, if anyone has time to spare, the SBS link looks like it might be interesting.

The battery for the Philips HeartStartXL defib is a standard one with a small indentation in the end. I think a standard one without this dent operates a microswitch so the defib knows you are using the "wrong" battery.
The official reason for this is that the batteries are checked to a higher standard......and sold at a higher price of course.
Is a similar thing occuring here either electronically or mechanically.

PS carefull use of a drill can replicate the indentation according to a sales rep for a Philips distributor when I commented on the price of batteries.

Yes, I'm mighty HP and if you want me it will cost you fortune

I've checked both datasheets and only difference might be on adresses 0x1b and higher (table on page 12)

About SBS forum. Annual membership fee is $150. Nice. I'm desperate, but not desperatly insane.

RoJo: Sadly, theres no microswitch. Life can't be so easy

I think that the HP simply stands for higher price.

I just recieved back my battery from that guy wich reprogrammed it And it almost works! He just changed coupe of values in battery. Theres no malfunction alarm anymore, but battery needs to be conditioned.

Good news Shamal but be prepared to have to do up to three full charge / discharge cycles to clear the condition battery message.

Nope. Just one was enough and the message is gone.
Problem solved.
And for anyone else, who might will encounter this problem in future, here are those values wich this guy changed:
Device name: DR36 -> TR36
Serial number: 0 -> 292
Manufacture date: 2000-09-18 -> 2008-12-13
