Default "New and improved" NiMHs

I bought some household NiMH cells for my remotes the other day; the brand is Energizer, not Sanyo, but the claims on the card sound a lot like the ones for Eneloop batteries: They come precharged, and are supposed to be able to hold that charge for "up to 5 years". Are these the same thing?

Also, how fast can an Eneloop (or it's possible clone) be charged ("C" rating)? Assuming the charger being used is one that is engineered for fast/peak charging, I mean. Like the ones we use for our flight batteries (on NiMH setting, naturally. )

I was thinking if I could find some of those teeny-tiny connectors used for the Hitec TX packs I could make a TX-pack -> Deans adapter and charge them on my regular charger. The long shelf life (plus perhaps a spare or two) would mean one less thing I would have to do the night before a flying day.

I've bought some. I haven't tested them but they seem to work as well as my eneloops. I charge both at 700ma with a La Cross BC-700.

There are a decent number of the limited self discharge (LSD) NiMh out now. Some are re-branded Eneloops, but most are made in China. Most are better than stock NiMh by a good bit, a few give Eneloops a run for first place. Eneloops still seem to hold onto the lead for long term reliability, but like lipos that's a VERY difficult parameter to measure in real life.

I charge at 500-1000mA. You don't want to fast charge them.

If you're going to learn to fly them, you have to learn to fix them.

I am such an idiot! Here I've had My Venom Pro charger for a year and a half now, and it came with a JST plug adapter! Granted the pins were "hooded", but a little careful knife work took care of that. I charged my regular NiMH TX packs with it, each at 1C, and they barely even got warm.

So now that I know that will work, can anybody direct me to a tutorial or thread on how to properly solder together nickel cells?
