Sorry to hear of your problem. How long does it take for the pack to charge ? At 6 amps it should take 35+minutes.

Just send the pack back to us and make sure you include your return address.

Danny,

This question does not apply to SMC batteries. Just batteries in general.

If I buy a matched pack of 3300/3600/3700/3800 cells and one out of six cells registers zero voltage while the others register 1.20-1.25V, should I assume that the one 0V cell is bad?

Bill

Yes that cell has one of 2 things. It could have an open circuit which means it won't even charge or it could of self discharged because it has an internal short in the plates so it actually deadshorts itself. Try charging the cell and see if it will charge. If it does charge it will have less runtime than they others so if you don't plan on deadshorting your pack you should send the cell back and get a replacement.

Hope this helps.

Does the pack get as hot as your other packs you charge with that charger ?

We just need to make sure it's the pack and not the charger.

At 4.5 it should take close to 45+ minutes to charge.

hey dannt just wanted to know if this was a good way to treat my new ib 3600 matched packs

Charge batt 6amps 4mv per cell
After run discharge at 30amp to 5.4v for the pack(linear on a cdr 5000)
Slap em on the smart tray down to .9v per cell
wait two hrs,
Slap on the novak for 30sec again just to get em equalized good before chargin

Your charger should be able to charge the IB cells at 4.5 amps and it's not a must to charge at 6amps.



DIMO your method should work well.

27 minutes isn't right. The MRC 959 is known to false peak (ask anyone) when it reaches a certain temperature. Try using a fan to cool down the charger.

Danny/SMC, I'm about to get a few of the IB3800 packs and I'm looking to find the best way to charge them. Guys at my local track are saying step charging (...with the Much More cell master) is the way to go. Currently I have a CE GFX which does not have this feature. Is there an added advantage to step charging which makes it worth the money to buy the new charger???

In my opinion I don't see that step charging will provide better results than a linear normal charge. Use .02 peak detect with your GFX and you should be in good shape.

I use a GFX to charge my 38's. With a peak detect at .02 and the pack came right off a pure resistor tray (30 minutes or so), I can get about 2650-2700 seconds charge at 6A into them. That seems to be in line with what I've been getting with the GP3300's at about 2350 seconds. I like to monitor my charge times on all my packs closely. The IB's have been very consistant. Hope this helps some.
