Thanks for the advice. The reason for asking was simply that I have a Wallstreet battery with newish cells in which, however, I believe the controller to have failed. It came rece…

I'm sure equill will be able to provide a great deal more about the chemistry, but it is my understanding that over-discharge is dangerous because conductive filaments can form in …

If the cells were ever over-discharged, some controllers will set a nonvolatile bit to prevent recharge. Click to expand... Is that why bunches of these stupid LiIon batteries …

I wonder if you could (i know you guys will hate this) super glue the tabs, then use conductive paint to connect the tabs? so no soldering or spot welding needed?

The controllers must be matched to the batteries, particularly in a lithium-ion pack. More than with any other battery chemistry, lithium-ion requires very special handling to avoi…

The controllers will handle different capacities. Lots of people have re-celled these batteries before. But these people also know what is going with these things very well. They …

Don't recell a LiON or LiPo battery. You're taking your life in your hands, unless you really know what you're doing. The smarts in there stop them asploding in your lap.

Apple really doesn't publish any technical information in that detail, which is a shame for old machines that are hard to equip with proper replacement parts. Anyway, some people …

Are the battery cells in Pismo/ Wallstreet batteries matched in any way with the battery controllers? In other words, is there any point in re-celling a main battery with different…

ive got one sitting around in my garage collecting dust

Thats a good machine you got there, hold onto it.

The 12 display is a DS 800x600 (or whatever the mac resolution is). Are the hinges loose? Major issues with wallstreets is the 2 cables that are along the hing to the LCD get cut …

There are two connectors to check on those. One is on the mid-left of the machine, under the keyboard, to the right of the PCMCIA card cage and cooling fan. It's covered mostly by…

I just bought a Powerbook G3 Wallstreet. It was sold as working from ebay. I open it up and turn it on and BOOM! Lines allover the LCD. The LCD is fine, but it looks like some kind…

What he said. Sadly, CRTs are pretty much "out of fashion now", including most of the iMac G3 models, meaning that they sell for quite little and even go for free. Your iMac is wor…

The 233 bondi blues aren't worth much, maybe $20. The G4 upgrade is worth more, probably at least $100 because of the rarity.

So a few months ago I bought an iMac from the thrift store to play around with, mostly because I have never used one before. I really bought it to teach myself how to repair and u…

Just go on ebay and buy one. They aren't expensive especially if you can find an install disc that was made for your model machine rather than a full retail disc. LEM also has a pa…

porter Of course you can, but I deliberately wrote 'working computer', which is entirely different from a functional computer without an OS. dogbiscuit Make sure also that you d…

.... and it is an offence to do so when the Mac was originally sold with one. Click to expand... I can sell a car without it being roadworthy as long as the buyer is aware.

Oh I see, I'm really with it, just didn't know it...

You are already running the latest version of 10.4! Apple's OS numbering goes 10.4.8, 10.4.9, 10.4.10, 10.4.11, etc. Generally, later version provide bug fixes and general improve…

Yeah, I think that makes sense. This is off the subject a little but, I'm using 10.4.11 now, can anyone give me any reason to upgrade to 10.4.3 or 10.4.4...4...5...6...etc (or to …

If the machine is for personal use then I would say that you're pretty much in the clear. Things like this are only really dodgy if you are using an install of an OS or other softw…

I think it's too slow for Leopard, it's a dual 450 Mhz PPC... Click to expand... I got that machine running leopard right now. Aside from a crappy video card and slow hard driv…
