I wonder why I never seem to have the problems others write about.Four year old laptop battery is still like new mostly plugged in run down a few times;higher price laptop carry it on trips but plugged in when I get where I'm going I do use a "cool Pad" type device except when on battery power the fan keeps things much cooler (and use WD-40 if the fan starts making noise;just a quick squirt). If you have a laptop a "cool pad" makes things last longer.

Are the manufacturers really this careless with their charging circuitry? They should be turning the current down to a trickle when the batter is charged.

Not just your battery like so .Anybody who have used the laptop has the trouble , some people used to take off the battery to extend the life when the external power supply and stable , but do a lot of trouble so . so the laptop battery with a period of should be changed.

is there any software that helps to optimize the battery level of prof.

Doesn't seem like an option for my little Macbook Air. Removing even an 'easily removed' battery isn't such a good idea. You're putting stress on the hardware that holds the battery in, and the mechanical electrical contacts, too. In other words, you might end up with a 'perfectly good' battery that either falls off your computer when you pick it up to move it, or that no longer provides a secure electrical connection, and then while it sits on the charger overnight, it overheats and starts a FIRE that kills you in your sleep. There are always little trade-offs with things. Your battery will probably last as long as you use your notebook. If you always use it plugged in, it won't matter much to you that your battery life sucks, and only runs the computer for as long as a UPS would run a desktop. And BTW, many 'battery' devices, including many notebook PCs won't even start without the battery attached. So disconnecting the battery when on AC isn't really even an option, and as the article does state, kind of a stupid option, since any hiccup with the power, or someone tripping on the cord, will lose you all of your work, if not send your structurally weakened (without the battery) notebook crashing to the floor. Most Lithium Ion batteries will lose substantial charge capacity within three years, whether you use them or not. Unless you charge them to about 85% state of charge, bag it with some silica gel and stick it in the fridge... in which case, you'll get little use out of the battery, anyway. NiMH and NiCad are basically extinct in consumer notebook computers. If you have a notebook old enough to have older battery technology in it, you've probably replaced that battery more than once already, and you could buy a brand new netbook for the cost of replacing that battery again, and that netbook will be better than your dinosaur notebook in virtually every way possible.

Agreed- while I'm definitely the type who likes to macgyver things, this is becoming more and more difficult with planned obsolescence- repairing my wifes tiny 10 inch laptop resulted in the screws that hold the thing together snapping the brass nuts out of their plastic tube anchors when I tried to unscrew them, which then necessitated further hours of repairing/reinforcing those plastic anchor tubes.

I got to this article a couple of steps after checking how much a replacement battery on ebay for my laptop is; $30.

For that price, I'm much better off just buying that than monkeying around with tiny electrical fittings designed by the manufacturer to break if a repair is attempted. Doesn't mean I won't attempt it once I have the good second (new) battery in hand, just that I'm old enough and wiser enough to know what I'm getting myself into...

While I'm definitely the type who likes to macgyver things, this is becoming more and more difficult with planned obsolescence/super cheapo construction- repairing my wifes tiny 10 inch laptop (ok, netbook, veeerrrry inexpensive, I think $250?) resulted in the screws that hold the thing together snapping the brass nuts out of their plastic tube anchors when I tried to unscrew them, which then necessitated further hours (yep really, HOURS) of repairing/reinforcing those plastic anchor tubes.

I fixed it, but it was time-consuming and quite a challenge. My wife was amazed I was able to get the thing working when I showed her what broke (tiny plastic tab on power button that stuck out to the side and pushed the actual tiny switch inside the housing).

I think my laptop is 3-4 years old, which may be the sweet spot for just old enough that they can't charge a premium for parts/supplies, and not so old that no one has one, thus no demand, thus no supply.

The lesson; buy a second battery before you need one, so you don't end up having to spend $100+ on it, or just retiring your laptop since it's such a significant percentage of buying a whole new one.
