EVA 5000 Cache Battery refurbish?

[jorgen325]

Is it worth it.
Took one apart, found these:
CYCLON
2 volt, 5.0AH, XCELL
Contains three soldered to a board.
Positive and negative connections only.
These batteries are $12/peice.
So thats like $45 per cache battery vs. $200.


Does anyone know if this will work, or are the batteries marked BAD on the circuit board to which they are soldered?

If I am able to successfully replace the cells on two cache batteries and replace both on the same controller at the same time, it should mark the cache batteries as good. Correct?

[jorgen325]

Well, $45 for replacement cells on one cache battery, I am going to try it.
I will let you know how it turns out.

[jorgen325]

New batteries just arrived.
Hopefully get them soldered up tonight and have them charging by tomorrow.

Keep your fingers crossed.

Hi,

There was a thread a while ago from someone who had successfully changed the cells in the battery packs.

I've not managed to find the thread again, but do recall that he concluded that there was nothing in the battery pack itself that determined that it was bad.

Regards,

From the description I saw, the battery cells had developed a higher internal resistance and the EVA charger did not supply enough voltage to 'fill' the cell.
He used an external charger.

Good news: Tried a single battery and it does appear to be working. Just installed, got a disk presented and configured.

It is still charging. I will keep an eye on it for a few days to see if it charges.

I have a warning for low charge, but it does say the operational state of the battery is good as well as the state of the battery charger. I really hope I don't have to find a way to manually charge these.

At the moment I only have one cache battery installed but will be fixing that very soon.

So the answer is yes, you can rebuild your own cache batteries.

NEED HELP AGAIN.

Granted, I only have one cache battery at the moment... I am working on getting the other three.

I have a low charge notice.
First day it recognized 2.5 VDC, after that (Its been four days) it has remained at 2.29 VDC.

Do I need to charge it?
Any idea how to charge it?
Single cell or all three cells at once?

jorgen325,

How did you make out with this? The fact that it charged to 2.29 is a good sign.
