I'm assuming when you get it, you put it in laptop and charge for awhile without using it. My question is, how long do you want before using it?

I don't recall seeing instructions on how long, but i left it charging about 3 hours. Both batteries are working fine!

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.

Be sure to follow the instructions in the manual re: first charge of the battery-- realize that your laptop will be off-use for 24 hrs. I have found that how long a charge lasts depends on what I an doing online; e.g., if I have been viewing a lot of video, charge goes faster. I mostly monitor by mousing over the power icon. Be sure to go down to 11% (ck manual) at least once/week for about 4x, as directed in manual, to extend battery's lifespan. Hope this helps. BTW: Anker's cust service is great too.

I think you should return the battery if it's not being detected by your laptop. Sorry for the late response. If you can't return it because it's so long since you purchased it try selling it.

From what I am seeing online, you can keep it plugged in to last longer (charge it). It lasts for about 15 minutes when fully charged and lasts for a long, long time (no real time table for the battery though). Can be a year, can be 5 years depending on usage.

I was very surprised when after a few months, my lap top told me to replace the battery. I would say I only had used it for about 8 to 10 hours total and it was generally plug in to a wall socket when I did use it.

Hartley: I find that question impossible to answer, because I just purchased the Dell lap top and even though there is information about the battery it's self, there is none about the length of time that it will last. Sorry! I found two things help in keeping the battery lasting longer. One, before charging, let the battery run down until the warning on your lap top signals says, charge it and always charge it all the way, don't pull the plug before you have a complete charge. This does help in keeping a longer battery life. Hope this helps.

I own 2 e280s, one of them since last July. I have found that it takes about 3 1/4 hours to charge fully. However I use a seperate charger to charge mine. I do not charge from my computer. I get between 15-22 hours on a charge.

You charge it in the laptop just don't turn the laptop on. The directions come with the battery.

It says in the manual to just put it back on the charger & leave it indefinitely, during summer season. That way it's ready to use. I don't have a spare electrical plug in where it's handy to leave it, so I just take it out of it's plastic bag & plug it in usually the day or night before I'm planning on weed whacking. It's charged & ready to use in 4-5 hrs usually, sometimes sooner.

You can't charge it before you install it. What you need to do is take out out battery, then when you insert new battery, merely leave the computer closed and leave it for 12 hours plugged in. That will charge the battery. Be sure you are not temped to open up the computer and try to do something on it while it is charging.

Sandi, I've had the replacement battery for about 4 months, run the laptop off battery only power for three nights of wireless connection (about 3.5 hours runtime) and then put unit on charge. Batteries like a draw down and then recharger, rather than keeping them on charge constantly. If I'm running on the power supply I remove the battery once it has charged and just run off the DC power connector. Batteries are rated in number of cycles (Charge/Discharge they can handle) so life span is fairly variable depending on how you use the laptop.

I've had mine for 2 years. It came charged so I've never charged it. I test it about every 2-3 months & it's still working; so I don't know that you'd need to charge it very often. Any research I've done indicated to charge it about once every 2 months with minimal use.

I have charged it once since i got it. it last a long time i believe or it feels.

Hi..... To the best of my memory.... It came about 3/4 charged but it has worked perfectly. I remember that I had to attach it to the laptop to bring it up to 100%. I have not had any problems with it in over a year. I hope that helped you.....Bill

Initially I charged it for 4 hours. That's supposed to last for 2 weeks or longer, as I was informed; however I have to charge it regularly for at least 2 hours.

I checked with my daughter, since I bought it for her laptop and she's the one who installed it. She did not get that message, but did mention that the battery needs to be charged before it will work. I don't imagine it would charge, though, if it's "not detected", but maybe you could leave it on for a while and see. You can probably tell I'm not very "techy". We didn't know until after we bought the battery that the laptop would work perfectly well just plugged in, with the battery uninstalled. If I'd known that, I probably wouldn't have bought the battery at all. Sorry I can't be more help. I checked with my daughter, since I bought it for her laptop and she's the one who installed it.
