I've only been tanking a few years but never have had a problem charging my batteries. I just set them on my bookshelf as they charge. I use a Venom Pro 2 charger and followed the directions. I think it's set for 3 amps charge current? I forget as I have it programmed in. Maybe it was .3. Whatever the instructions said (you just moved the decimal over per the mah of the battery).
I'm very tempted to do in-tank charging as it's a pain to have to flip the tank on its side to pull the battery pack.

Try moving that down to about .5C for those batteries ok? You will get a lot more life (maybe runtime too, but that would be possibly too minimal to measure) out of them and they will stay cooler when charging. If it is a 3000mAh battery then do about a 1.5A or so charge. It should take around 1.5-2 hours if the battery is fully drained. That is the rate I use on my 3000mAh batteries. For the 5000mAh packs I charge those at about 2.5-3A max. Only lithium packs (and my really good ones at that) do I ever charge at anything over 1C ever.
