OK, I have the plug - one tip B, one tip M.

I'm still a touch confused, though, as both tips have a "-" on the back and a "+" on the front (plug) side.

When I bought them I didn't see a choice of buying + or - plugs... am I missing something?

OK, so after having power issues at a recent show (and thus not getting the last 30 minutes or so recorded... DOH!),  I vowed to never let this happen again and finally picked up one of the RB-270 batteries off eBay and all the necessary adaptaplug hardware, and got everything working fine. 

My question is... what's the best way to get this battery "conditioned"?  I fully charged it right away when I got it (this was a few weeks ago, but I'm assuming it's still fully charged). 

Do I need to run it down all the way to zero and then give it a full charge again?

Is there a preferred method of draining/charging to get maximum charge and long term best performance out of these things?

Acidjack - did you get the polarity thing figured out?  The markings are a little hard to see - the important thing is to reverse only one connector (it doesn't matter which one).

bump

I'm planning to use the battery to record a show tomorrow, so I'm wondering what I need to do.

Ran some tests at home with my whole rig & the battery - maybe an hour total, and my battery is still showing "almost full" (the "full" light out, all others on).

I posted some extensive info on Li-ions awhile back, see this thread:

Thanks Lee, that's what I was looking for.  I figured there had to be some discussion here on TS, but my searches with "rb-270" and other specific terms were coming up with nothing, and the more generic ones were getting way too many results to sift through.

Interesting, because I always assumed it was best to fully drain these before recharching (WRONG!).

So it sounds like the "40%" rule applies right away, and since I'm probably at 80-90% right now, I should just record the show tomorrow and that would bring me down to a good level for storage.

Just to be clear, is there a cable to go between b tip and m tip that is available at r shack or do you make the cable?

The cable is a 6ft cable (not 6 inches like the web site says).  My local RS store had it, along with both tips:

You can also get two single adaptaplug female sockets and connect them together if you need a cable less than a foot long. The pigtails on this are about 5" long. Two of these are cheaper than the 6' cable linked above.

As always, check with a VOM when done to verify polarity.

thanks for your input.

i went to a small town radio shack and found the adaptaplugs B & M but not the cable to go in between them. the lady told me the cable doesn't exist so I walked out of there scratching my head considering I saw it on RADIO SHACK'S WEBSITE EARLIER IN THE DAY.

I'll check locally later this week at radio shack...although Ted's power cable is very reasonably priced considering the b&m plugs are $7 each and the cable is another $9.5.

M: http://www.radioshack.com/product/index.jsp?productId=2103614

reverse the tip and sleeve check with volt meter and voila!
