Default Help with NIMH shelf life, please!!!

I need some cheap 4cell packs for practice. I found a seller on ebay that is selling sanyo 3600's and GP3300's that are matched at a pretty good price. I don't know how long he has had the cells or matched them.

What is the shelf life of Sanyo 3600's?

What is the shelf life of GP3300's?

What are the chances of me getting dead cells from him?

from my previous experiance w/ gp's is that they hold up fairly well. I just got some GP3300's last week from a buddy that was selling out. They were the epic Monster Metal cells, 2 packs matched by lightspeed. This guy has been out of r/c for about 3 years (these cells are old). For shits and gigles, I cycled them and they ended up holding 3400-3500mah! (I even charged them at 6 amps (delta peak was at 5 a cell!!!!!!). Voltage was about 8.3 after sitting for about 1/2 hour after it peaked. I was shocked!!! Good #'s for its day

So should I get the GP3300's? They are brand new. Again I don't know how long they have been on the shelf for. Could they be potentially dead?

I had nothing but bad experiences with cells that been in the shelf for to long. But then again not with GP3300, just sanyo 3000HV and GP3700.

Its a risky move. Specially considering that even a bad, non matched IB or EP will outperform the best GP3300.

It's your choice, but personally i wouldn't pay for a cell this old without the chance to try it first

Just because they are 3300/3600 cells doesn't mean they are "old" as some people have suggested.

Yes they make 4200+ mah cells now, but this does not mean that the cells this guy is selling aren't new.

They would still manufacture them, albeit in smaller quantities.

If the company is big enough (the person that matches the cells) they might have even got the battery manufacturer to do a "run" of 3300's.

I think GP3300 are still being made (at least they are on GP catalogue). But why would a matcher bother to match them?

Why not? Some people are willing to pay a bit less for slightly less powerful cells.

I wish the new IBs and EPs had half the durability of the old GPs. I take care of my batteries very well and I still get dead cells all the time. I almost never had a problem with my GPs or IPs. It's a shame that no one is really using them anymore because they have "slightly" less punch.

I'm thinking I should pick up some GP4300s and give them a whirl! See if my laptimes drop. At least I wouldn't have to worry about my packs exploding.

Hit the nail on the head right there
