None of the above is true anymore, it was true back in the days of NiCad batteries. Laptops use Li-Ion batteries. Li-Ion just likes to be fully charged all the time, the best way to accomplish this is to simply leave your laptop plugged in all the time. Every time you cycle your battery you lose a tiny amount of capacity.

I have a ASUS UL80Vt-A1 14-InchIt suposse to have 11 hours of baterie life, but I see this jumping fron seven hours to 3, to 5 etc., so I do not know what is left.Any sugestions?Thank youfor your help,J C Miranda

what you are seeing is an estimate based on the last hour or so of usage, that will jump all over the place.What does not jump all over is the amount of power left, for instance 50%, 75% etc.Just base your usage for how long it took you to get to 50% using the settings you normally keep it at.

Not sure where I originally got this info, but for years I've sworn by a complete first charge followed by a complete discharge, followed by another complete second charge (and keeping the machine turned off during at least the first exercise). All future use minimizing actual battery usage, so basically keep it plugged in whenever possible or at least charging every night. My 3 yr old LG cell phone still gets 3-4 days/charge (vs 5-6 days brand new) and 4 yr old laptop gets 2 hrs (vs 4 hrs brand new)...Hope this helps.

Since you didn't formulate a properly grammatical sentence, which prevents me from answering your question simply: ill answer the two ways it may be meant. 1) If you mean, how long did it take to charge the battery the first time: none. It was already charged. 2) If you mean, how long should i charge the battery, then up until its 100%, then drain it fully.

Charge a good 8 hours the first time. And recharge it after each use. The batteries won't overcharge and the charger shuts off by itself.

Hello, I just plugged the computer in with the new battery and let it charge for at least 24 hours. It works fine!

I'm not sure what you are expecting by calibration, but it should be able to charge completely plugged in, and then used unplugged till it draws battery down to 10 I'm not sure what you are expecting in the way of calibration. But you need to charge battery till it shows 100% and then use the laptop or leave it unplugged until the battery drains to 10%. They recommend this 2 or 3 times before using. I have had good luck with this battery and have used unplugged for as many as 7 hours. Times depend on laptop settings such as screen brightness, dvd usage, etc. If you are still having an issue perhaps you received a bad battery and need to talk to manufacturer, or place you purchased, and also make sure your laptop is showing that the battery is indeed charging. Best of luck

I got somewhat less than 2 hrs (but I wasn't doing much other than moving the mouse to keep the screen from going to sleep) - about what I expected. This is a basic (6-cell) battery. there are extended (9-cell) batteries that will last longer. Also important to follow the "break-in" procedure (full charge - full drain - full charge, etc). Some laptops may have to "learn" how to charge a new battery before it can do it efficiently, and fully.

You can still buy brand new replacement batteries for these for about $75. On a new battery, this machine will run 3-4 hours on a single charge. When the battery gets old, as in any laptop, it won't hold for more than a few minutes. But that has nothing to do with this particular model of computer. That is true of any computer and any rechargeable battery system. Depending on which one you get, you might get 30 minutes or 3 hours of batter life. It's impossible to know. Ask the seller. If the batter is less than a year old,you will get very good battery life out of it ... at least 2 hours. You can still buy brand new replacement batteries for these for about $75.

The first time, I was surprise when it finally finished. It really takes 24h! My old one doesn't have the charge progress indicator so I assume that I never charged it entirely!

Depends if first charge or normal charge. first charge is 10-12 hrs. Normal charge is about 3 hrs.

A full charge for the first time should take about 4 hours. The 4700 works for about 2 hours on a full charge. Keep your car cord pluged into the unit when ever possible to keep it at full charge.

I threw mine out because I could never get it to charge again after the first time. The first time, you should charge it for about 12 hours.

hello if you would like to know which are good recommendations of charge for the first time, buy one because I'm doing the devoluvion since the device does not grab full charge, and I raises questions when making a new purchase

I would charge the battery first. I believe those are the instructions anyway. In fact, I believe there are specific charging procedures initially to get the best life out of the battery. If you continue to experience issues, I would contact the vendor/manufacturer.

I don't believe ours came with instructions either. We just put it into my sisters computer, let it charge until the white light came on that tells her its charged and then unplugged it and started using it. The only thing I can suggest, if you haven't done it already, is to let the battery charge for a full 24 hours. I know that's how you used to have to do it and maybe it will work now. If nothing else, take it to Staples, they have a computer check thing that I believe is free and they may be able to check the battery itself as well as your computer to make sure something isn't wrong in your charging system. I hope I've helped. Good luck. I don't believe ours came with instructions either.

Yes that's correct, since it already comes pre-charged out of the box.Also my mistake it is 2 hours not 3 sorry. I just remembered that for first time charge after draining the battery, you only need to set it on the charger for 2 hrs.

I believe, I charged this new battery for approximately 8 hours before the first use. Now, it takes, perhaps 1-3 hours to fully charge. It's been a good battery...much better than the OEM.

The first full charge is crucial. Charge it the full 24 hrs or more. The unit will regulate the charge, so you can keep it plugged in and on charge for as long as you want. Clore will send you recharging reminders via e-mail if you subscribe. You also receive other valuable info in those newsletters. Good luck.
