Pure Energy Battery Corp, Amherst Nova Scotia, Canada (1-800-868-8756) They are rechargeable alkaline (...) (25 years ago, 16-Nov-99, to lugnet.robotics)

| | | | Regarding Rechargeable Alkaline Batteries: DON'T USE THEM DON'T USE THEM DON'T USE THEM DON'T USE THEM Wh- ..Why? you ask, bewildered. Well, I suppose maybe my reaction is a bit strong, but I absolutely hate these batteries. They're a nightmare to (...) (25 years ago, 17-Nov-99, to lugnet.robotics)

| | | | | I've been using them in a GPS for a couple years. They don't get a lot of use, but I've never had any problem. When using the GPS I like being able to always start out the day with a fresh set of batteries. I probably never did a full discharge of (...) (25 years ago, 17-Nov-99, to lugnet.robotics)

|
| | | | I fully concur. They seem to work well initially, but managing a set of them is fraught with peril. It wouldn't be so bad if there was a "bad battery" tester. But there isn't. So some freak battery that isn't cutting it gets in your pack, and you (...) (25 years ago, 17-Nov-99, to lugnet.robotics)

| | | | | | | Pictures of RCX on external batteries —Arjen Gerstel
|
| | | | | | Kevin, I'm already using a set-up as you described. I suppose this is what you mean: (URL) you can see, I'm using 8 NiMH cells. This gives approx 9.6 volts. The motors actually run slightly faster than on regular alkaline batteries (and a lot (...) (25 years ago, 17-Nov-99, to lugnet.robotics)

|
| | | | | | (...) Yep! That's the beastie! Although in my mind's eye I was using sub-C cells, as I've got plenty of them. And I was soldering them together, as I've done it before. But we can do all sorts of things in our minds' eyes, no? :) It occurs to me (...) (25 years ago, 18-Nov-99, to lugnet.robotics)

|
| | | | It's strange to see you describe the "how to find the bad cell" problem with reference to Alkaline cells, then go right on and suggest the use of Ni-Cad battery packs! Ni-Cad battery packs have the same problem that any other type of serial (...) (25 years ago, 18-Nov-99, to lugnet.robotics)

|
| | | | | I don't know about other rechargables, but bad Ni-Cds can be identified. The charger I use has a test mode which measures the battery's characteristics (perhaps putting a load on it a observing the voltage discharge curve?) and indicates its output (...)

| | | | | | No, you all missed the point. Jack was talking about the idea of LEGO(r) providing an external NiCad battery pack solution to certain perceived problem (the difficulty of taking a robot apart in order to change the batteries in an RCX, Scout, etc.).

| | | | | | Hey, all I want is to have the smallest lightest RCX and that means leaving the batteries out of it. I don't really care how they do the connectors. I even have one of those boxes with the button. I just think power source and power sink should be (...) (25 years ago, 21-Nov-99, to lugnet.robotics)

Actually, finding a bad NiCd is easy - split the battery into its component cells, and individually charge/discharge them (or even just check their voltage and polarity if they're REALLY shot) to rate their characteristics. Dedicated racers, (...) (25 years ago, 18-Nov-99, to lugnet.robotics)
