Help! NiCd charge graph, battery bad?

Hi, I was charging up a somewhat old Futaba 6EXA trans. with my Bantam e-Station BC8 charger and graphed this out on my comp. Does this look bad? It all jumps around. Does it look like I should cylce it or just pitch this battery? Thanks!

P.S.-- Red is Voltage, Blue is Current (charging at 1 amps) and Green is the capacity (mah) that the charger has put in the pack so far.

I wouldn't trust anything that old.
You can get a battery that will fly all weekend long for about $18. Dont risk it.

Does it go to 6.0 volts? Does it hold 4.8 volts? What do you fly? A foamie or something you fly in front of you? If you answer all of the questions "yes",then go for it.

Dumb me! I need to read more and write less. If your transmitter holds the charge,stick with it. All you have to do is spend money.HA! The old batteries has nothing to do with "good or bad". I have some that are 6/10 years old(SR batteries) and are good.
The adage that old batteries are "bad" is false but ,for safeties sake and the "others", change the battery. Leon

SR Batteries ranks high on my Fecal Roaster !
I had a terrible experience with So called quality SR Batteries. [Tx pack]
Less than 1 season's use, and now died in just a few minutes... I almost lost my plane.
I asked for support from Larry, and all he wanted to do is make excuses to deny any responsibility for his product.
He claimed I didn't buy it from the right people, so it wasn't his problem. He complained about everything but my spellin' . I thought I was buying a quality, [and expensive], product make in the US, but I was denied an adjustment because I changes the connector! He made his profit, and I got screwed ***? ... Then he claimed HE was a victim ??? Who's the victim ?

Those dips are the charger not the battery and as in any graph if you zoom in enough on the scale a milli volt can be made to look like a mountain.

I don't know your charger at all but it looks like it times out to test the resting state of the battery pack. Thats a good thing of course.

If it holds voltage keep using it. Your battery voltage was never below 10.5 volts and thats still sufficient to drive your transmitter.
