Confustion on Mah charging. -

I was reading over on Rcu, and someone said they have 14000mah cells, but no charger today could charge them. I thought mah didn't matter, just took more time to charge? Anyone care to elaborate?
The person that said that was an idiot. You can charge them. You may not have a charger that can do 14A charge, but I have one that does 10A. Fast enough. Insanely heavy cells tho I bet.
Yeah, not many (if any) chargers will allow you to enter 14Ah. So, you just enter the highest the charger will support. The only issue I can see is that some chargers may stop after ~1 hr as a safety net. Just restart the charge.
With the increasing capacity, voltage, and charge C rate, pretty soon we are going to need true CC/CV supplies. Good idea, but no charge profiles, safety for cell count, etc.
but still.. I have (nimh) 10000mah D cells I charge on my Triton, and it does fine. Max setting is 6000mah, but even at that I set it to that, let it "trickle" charge @ 1A and it runs fine overnight. So there should be some ways around what Brian mentioned as concerns if you really wanted them.
Did I mention they are huge tho? Why would you ever even want 14000 NIMH packs?
