DV7 Battery Care Question

It's been since the DV6000t that I looked at battery & notebook technology.

From then I believed to cyccle the battery a couple times and store it out of the machine @ around 60%.

Is it still so? Will just plain leaving it in the machine all the time plugged in shorten the life or effciency?
Or have things progressed?

 

I can only speak for myself, but I have had absolutely no problems with wear on the battery by keeping it in the laptop all the time, its been about a year, and i only have 1%wear

 

I used to hear if you left it installed due to the amount of cycles in a battery you were using them up (cycles) and its best to only have them installed when you are going to use them or anticipate having to anyway.

The really Serious guys will long term store them in a refrigerator a 60% charged.

I'm kind of hoping technology had advanced in the last few years and the laptop has built in long term care. But now one is bragging on it so.........

 

All batteries will die someday. First there was memory effect that you would combat with deep discharges. Now new batteries don't have such but instead they just pretty much die when time's up.

That 60% charge in refidgerator is about best way to conserve battery.

This tc4400 I just bought, batterybar still says 0% wear but it doesn't charge over 38% anymore. That would probably mean that 4 out of 6 cells are dead. I still get 1.3hrs from it but I ordered a new one from ebay:

55Wh battery that should give 5+hrs for 36 euros and free delivery. If the new battery lasts about three years again, that's an acceptable price for me to keep laptop almost always plugged on when I'm at home or office.

 

Personally, I don't think removing the battery will save it that much longer; I'd only bother taking my battery out if I wasn't going to be using it for a month or more, and even then, I might not even bother.

Plus, you never know when someone will pull the plug
