Re: 3400c Li-Ion Battery?
Subject: 3400c Li-Ion Battery? I have one that seemed to have discharged itself and now won't charge. All 4 green lights come on however. Is it a gonner or is there a chance to save it? Wouldn't charge in a dual charger either. It tries to charge but seems to give up after about 10 seconds. Same thing happens in the Powerbook. Thanks Li-Ions give you very few options. They can develop a digital memory if you have rarely let the battery run down. The fuel gauge computation needs to be updated as the battery ages, but if you've mainly kept the PB on the charger, then the updating hasn't happened. A few complete charge/discharge cycles will fix that, if that is indeed the problem. Re-celling is hard to do. Because it's dangerous, you can't buy loose cells on the open market. If you do find some, just be careful. Don't solder to them (spot weld the battery connections), or you're risking rapid uncontrolled disassembly. This is *not* an operation for the casual hacker. As for shelf life, Li-Ion batteries are famous for eating themselves whether they're in use or not. So stocking up on a lot of them is likely to lead to some disappointment down the road. To maximize shelf life, most manufacturers recommend charging to a level of about 40%. If too high, self-eating occurs. If too low, ordinary self discharge may take the cells down to the point where another protective circuit kicks in and prevents charging altogether. Good luck, and be very careful! -- Prof. Thomas H.

LiIon batteries have been around for a while, this has come up once or twice on any forum I've viewed, especially camera and PDA forums I guess. http://www.batteryuniversity.com/parttwo-34.htm is one good spot; the wikipedia entry for LiIon is pretty good. Googling finds others. Basically: LiIon batteries lose capacity over time whether you use them or not; storage condition makes a difference. 50% charged and cool helps a lot for storing, so if you have a spare battery that you don't use much that is a good thing to try for. for the battery you are using, it's best to keep it topped up rather than letting them go totally down. HEAT IS BAD for all batteries, but it has a marked effect on LiIon. It's a good thing to keep them cool at all times you can manage. So take that iPod out of it's protective case when charging, don't charge your laptop when it's on the sofa, put it on the wood table, etc. Replies I got from makers of replacement LiIoon batteries when I was buying spares indicated 50% loss of max capacity after 2-3 years wether they are used or not; so stocking up on many spares was not recommended, even by the guys who made the batteries I was buying (www.laptopsforless.com, battery for my Sony Clie UX-50 -I highly recommend these guys for batteries for many devices).

Also, there's a electronic component on each cell that ends up optimizing that cell, is my casual understanding, and it's next to impossible to get naked batteries with that component assembly on the consumer market. It's not just like getting a NiMH cell or 6 and DIY. There are good resellers of assembled packs for most applications; not sure about old PB battery innards but I expect someone somewhere has figured out the form factor.

If all 4 lights come on, that generally indicates that the battery is fully charged. If all 4 lights come on indicating a full charge, you try to run your Mac from it, and moments later your Mac goes to sleep, then you probably have a battery that is close to death.

Yep, that sounds like a Li-Ion battery that has reached the effective end of it's charge-recharge life. Li-Ions may not have a memory effect, but they do have a limited number of charging cycles. When they get to the end of their life, they die a lot like this. If all 4 lights come on, that generally indicates that the battery is fully charged. If all 4 lights come on indicating a full charge, you try to run your Mac from it, and moments later your Mac goes to sleep, then you probably have a battery that is close to death. Rats. Anyone know how to get these batt cases apart? Getting that type of battery apart isn't easy. To make matters worse, recelling a Li-Ion battery is non-trival. You have to find cells with exactly the same specs for the intelligent battery charger in your PowerBook to charge it without making it explode or catch fire. - Drew -- Author of ClassicStumbler email: [EMAIL PROTECTED] web: http://www.alksoft.com/ Visit the PowerBook 5300 FAQ! http://www.alksoft.com/5300_FAQ/ -- PowerBooks is sponsored by http://lowendmac.com/ and...
