Dell :: Parts For Your Batteries Vs. Generic Batteries
Jan 7, 2010The battery of my D620 is finally dying after 3 years. I need a new one but don't wanna spend too much since that laptop will be replaced soon.

Aug 8, 2009Now that I've got a new MBP with an awesome 7-hour battery, I want to prolong my batteries lifespan as long as possible (especially since it isn't user replaceable!).
According to this thread: Notebook Battery Guide
I should never fully discharge my battery to 0%. Apple's battery calibration tips [url], on the other hand, tell me to discharge to the cutoff point, then leave computer in sleep for 5 or more hours. Won't this discharge the battery to 0%?
I'd like to think that Apple wouldn't tell me to do something that would harm its own product, but I just wanted to double check for sure.
Also, what level are you guys usually draining your batteries to before charging them? The battery thread says 10-20%.

Apple :: Pre-Unibody Macbook Pro 15" - Batteries Are Dead - Won't Even Charge
Jul 6, 2009So, during the summer I work for my school. Last summer we got 2 MBP 15", and now both batteries are dead. By dead I mean won't even charge. They are literally dead. What can I do? We will probably end up buying new batteries, but what may be the cause of this?
View 10 Replies View RelatedSony :: SZ Battery Lasts 10 Minutes
Jul 24, 2009My dad bought a Sony SZ18 when it originally came out three or four years ago and ever since has been very happy.
About 3-4 months ago he got a new replacement battery for the computer as its original battery (in the end) lasted about 10 minutes which wasn't very good. He then bought a new battery and has been using this since.
It was good up to about last week when the battery started having the same problem as the old battery.
He didn't want to have to buy another battery,he didn't want to buy a new computer because the new core i series architecture is coming out and wants to buy a computer with that.
Sony :: Vaio VGN-NW270F Battery Lasts 2hrs
Mar 8, 2010I have owned this laptop for 2 months. I don't play video games or watch movies on it, just normal web browsing. After a full charge I only get 1hr 59 min remaining of battery life.
all reviews say average is 3-4 hrs...again, i've never seen it say over 2hr remaining after full charge.
I took it into the sony store and they replaced the battery. this new battery gives me the same result. Is this something i should be concerned about? what are my options at this point?
Lenovo Yoga Flex :: 13 - Battery (60% Charged) Lasts For Only An Hour?
Feb 21, 2013I have been using my laptop at home for the past 6 months for most of the time. When I am running the computer I have it charged with the Optimised Battery Health option, so, less than 60% is charged all the time, and I have never removed the adapter if I am using it. But, when I went to sleep I removed the adapter from the laptop.
What happened: Today finally I am taking it out for a breath and it lasts for only an hour!!!!
What was on: I was using it to do some research online only. So technically only wifi was on - not even bluetooth or video or music play. I only ran Chrome, a dictionary software, and my Dropbox. Well, I actually turned the screen into very bright, which was full brightness minus two presses of F11 (to decrease the brightness).
Would it be a cause of upgrading to WINDOWS 8.1?! (like upgrade to iOS 7 on an Apple phone: running latest iOS consumes lots more battery capacity in older iPhone..)
Dell :: XPS M1330 9-Cell Battery Now Only Lasts About 100 Minutes After Updating Drivers And Bios

Aug 21, 2014I have a W530 that is about 7 months old, and the battery, which used to sustain for 4-5 hours with moderate use of the computer, all of a sudden lasts no more than about half an hour. It was not a gradual change, but more overnight. When I look at the power manager, I note the full charge capacity of 10.23 Wh, which is extremely low for a battery that is only 7-8 months old. What would cause such a dramatic reduction in battery capacity in a matter of days, when I did not use the computer differently, or is my battery simply defective?

Jan 31, 2009i was just wondering about a couple of things about my d630 and see if i am out to lunch or is there something wrong with my laptop?
1. The Fan, the fan seems to run on full throttle all of the time. i used to have d800 and it will never did that. Its not like it does it when its hot or needs power, but the fan runs at full speed all of the time? is this ok?
2. Battery life - may be due to the fan, but my regular cell battery only lasts about an hour or an hour or 15 max? is this normal .....
Dell :: Why Do Batteries Cost So Much
Jan 29, 2010(I'm talking about original and genuine OEM batteries and not cheap generic batteries. )
I find it odd that brand new, genuine OEM Dell batteries bought off ebay cost 1/2 or 1/3 of the Dell website prices.
How is it possible to get an original OEM battery from Honk Kong with free shipping and still only pay 1/3 of the original price? I simply don't understand how the chinese suppliers can make a profit out of that. At the same time UK retailers on ebay sell their batteries for about 3/4 the price of a battery from dell.com. It's still a good deal, but not as good as the chinese batteries.
Take a look at these batteries for example:
6-cell for XPS M1330
[url]
9-cell for XPS M1330
[url]
I bought both of them for less than what a single 6-cell battery would have cost in my country and shipping from China only took 8 days! I've checked these batteries with Everest Utlimate edition and they show 0% wear and the battery life seems to be to spec.
Dell :: Outlet -- New Batteries
Jun 6, 2009i'm considering buying an e6400 from the outlet and i've been trying for days to find a configuration that i'm happy with. i've noticed that the hardest to get "right" are the screen and battery which is where this question comes in.
when i get an outlet "scratch/dent" or "cert refurb" are the batteries the original ones or are they new? i ask because if they're the old ones, there isn't too much of a point in getting a 9 cell over 6 cell because the batteries have probably lost a bit of capacity already.
Dell :: Generic Batteries?
May 10, 2009Anyone have experience using generic battery replacements to Dell's batteries? My Dell battery died (not gradual loss - it had a heart attack and died) about two years into getting my notebook. If I can spend $40 on an ebay battery that's comparable to Dell's $160, why not

Nov 30, 2009On the Belgian website of Dell I can configure the Inspiron 13z with a 8-cell battery. But this battery sticks out form the bottom of the laptop. On the accessories tab of the configuration tool I can also select a 6-cell battery (451-10702) that doesn't stick out. But my Dell contact said this battery is not supported on this model. So their website must be faulty.
View 10 Replies View RelatedAcer :: 3810 Different Batteries
Mar 15, 2010since the 3810 is really noisy with AC plugged in, I decided to buy another battery to only run it on batteries.
But I found several different models running with the 3810 so I am confused and wonder if anyone has made experiences with original/3rt party batteries and would recommend a particular one. What I found so far are
4400 mAh; 6 cells; non-original EUR 34
6600Mah; 9 cells ; non-original; EUR 42
5600mAh; ? cells; ORIGINAL; EUR 115
5600mAh, ? cells; "100% New Genuine Lithium-Ion Rechargeable Battery" EUR 37
In particular, are the 6 and nine cells akkus of equal size or how much will it exceed the laptop?
And are original batteries worth thrice the price?
The original one has only six cells right? I did not find any ORIGINAL 9 cells battery or do they not exist?
HP/Compaq :: Generic Batteries
Oct 3, 2009I was thinking about getting a 12-cell extended battery for my dv5-1xxx series notebook, but they are very expensive for the HP branded ones.
I see a lot of generic ones, but I know a lot of them are not safely made and the quality is poor.

From what I gather, can quickly and safely charge 80% of the battery in 30 min! 3 year warranty is also a nice bonus. I hope the battery shelf life and battery power is good.
HP/Compaq :: Extended Batteries
Sep 28, 2009Speaking of batteries, has anyone found a good outlet for extended batteries. I can't seem to find one for the HDX 18. You'd think manufacturers would make them readily available for these desktop replacements. Even in economy setting I barely get 2 hours before my regular battery runs dry.

Jan 1, 2009I have a Dell D620, approx 2 years old that has been a real work horse....until recently. For some unknown reason it now does not recognise either of the two batteries I use in it. The spare one slots into the DVD bay when I need extra juice.
Now I know that batteries deteriorate around the 2 year mark but both of them on the same day doesn't seem right??? All I now get is the yellow flashing battery indicator and it only runs on mains powere.
I'm happy to buy another battery but would prefer to resolve the current problem first if at all possible - any suggestions greatly received?
Acer :: Travelmate Eating Batteries
Oct 20, 2007The battery on my Acer Travelmate 2310 has gradually been getting worse over time.
It got down to lasting just 2 minutes on the battery after a full charge.
Then one day it wouldn't start at all.
I bought a new battery, charged it overnight and it semmed to work ok until the battery ran out again.
I have put it on charge, but it seems dead again.
When I hit the power button the battery light just flashes.
Has it eaten another battery, or is there anything else that could cause this problem?
HP/Compaq :: Difference In HP's 9 And 12 Cell Batteries
May 1, 2009I am looking at the differences between the dv3t (which comes with a 9 cell) and the dv4t (12 cell).
With the discount coupon, I can get a model with equal specs for the same price. However, the only difference is the smaller form factor in the dv3t, and the smaller battery. Does the smaller 13" screen for the 9 cell compensate same battery life for the larger 14" screen and the 12 cell?
HP/Compaq :: Boston Power Batteries

View 3 Replies View RelatedDell :: M1530 Owners With 9-cell Batteries
Mar 30, 2009So I haven't even had my laptop for a year yet (will be a year at the end of May). I bought a separate 9-cell somewhere in late June or early July.
I've noticed as of late, that my battery life is nowhere near as long as it used to be. With all my tweaks and once it was sitting at the desktop idle, Rightmark would regularly say I have almost 6 hours of charge left. As of today, I don't even see 4.5 hours, sometimes barely 4 hours.
I checked the battery by holding down the button at back; the lights go away instantly and then 3 of them light back up.
I definitely didn't buy this thing with the expectation that it would lose over 30% of its capacity in barely 10 months of use, especially considering a new battery costs between 100-150 bucks.
Dell :: Anyone Ordered DENAQ.com Laptop Batteries?

I have never heard of this company and don't want to give my credit card info without getting any positive feedback from this valuable forum first.
