interesting, ive never seen these before. are cheap (cheaper than good nimh 9Vs) and have pretty high discharge currents

good data here

I have been using the EBL batteries for some time and they work great. The price (22 USD for four, including a charger) is pretty good too:

just got them.. they weigh like nothing

Not compatible with a 4 9V Nbox? I know I need to be careful when ordering the PowerEx's to ensure I'm getting the 9.6V version instead of the 9V version. The 9V rechargeable batteries wont power the Nbox the way a 9V Duracell copper top would.

not sure, nick is pretty secretive about the operating voltage of the nbox, but all of the rechargables (particularly the eight-cell 9.6V NiMHs) should have plenty of voltage as 9V alkaline in normal use go down on a relatively constant slope to 6.0V

depending on type, most rechargables have a flatter curve between 7.5 and 10V

more than you ever wanted to know (thanks to justme for turning us on to this site)
