HP/Compaq :: HP 12-Cell BatteryHow Long Before You Need To Recharge
Sep 24, 2009
For those of you who are using the 12 cell battery, how long did your battery initially last when you first got it -- and now, how does its battery life compare to how long it lasted in the beginning?
I have an HP dv5t that I bought 9 months ago. I was kind of disappointed that I only got about 3 1/2 hours from it, and now, after the 9 months, it's down to 3 hours.
I keep it plugged into my laptop at all times, even when not in use, because I like the fact that it lifts up the machine a bit, and helps with cooling. I don’t use the battery that often, (just mainly when I’m traveling). But I do make sure that I fully discharge it (use it) about once a week – as has been recommended by many posters.
So, what’s your experience with the 12 cell battery?

I have an HP Pavilion dv6000. When I purchased the laptop, I chose a 12 cell battery, and it has a sticker on it that states: Replace with 451864-001. My battery went bad, and I purchased a replacement at the HP Parts Store online. I specifically chose a 12 cell replacement, which brought up the same part number, i.e., 451864-001. However, when it came in the mail today, the battery looks like a 6 cell, as it's about 1/3 the size of the old 12 cell, despite my purchase receipt which states that I ordered a 12 cell and the packing slip which also states that HP shipped a 12 cell. The model number of the old battery is HSTNN-DB32, and the model number of the new battery is HSTNN-DB46. Unless they were able to shrink the 12 cell to make it resemble a 6 cell, I'm pretty sure I received a 6 cell, despite the notations in the purchase order and packing slip.
This is a long way of asking, is there a tool that I can install that will tell me how many cells are contained in the battery? The battery, itself, does not state how many cells it contains. If it is a 6 cell, as I suspect, HP will be getting it back.

Couple of questions:
1. Does the 9 cell PROTUDE out the back and is it thicker than the normal 6 cell?
Would love to see a photo comparing both if possible.
2. Practically, in terms of percentage, how much more run time? 50%? 60%?
3. How much more weight?

First of all - Is it okay to keep the Laptop plugged in even when it is fully charged and in use. The Battery even when completely charged shows charging while in other Brands it shows that it is on AC power, so I am a bit confused. Because if it is still being charged then the over-charging might harm the Battery and reduce it's life considerably.
Second - If it's Ok to keep it plugged in when using, at what interval we should let the battery discharge completely because I think it is important to let it discharge completely once in a while.
Third - After charging the Laptop completely and Shutting it down (while continuing charging and unplugging it only after it's Shut down) when I check it after 8-10 hours of no-use the battery is around 15 percent down, i.e it loses 15 percent of charging even when it is Shut down. But if I keeps it in Hibernation it loses only around 10-12 percent of battery at most. Which i find quite amazing as it should lose more battery in Hibernation mode as compared to Shut down, isn't it?
These are my questions and I am sure many other users like me will also be getting these questions on their minds and looking for an answer, so it will be of great help for them also.

I have an XPS m1330 (T7500, 3 GB RAM, 8400M GS GPU) and had a bad 6-cell battery that wasn't holding charge.
Dell sent me a replacement, but they've sent me a 9-cell which I don't want b/c it's heavy, adds bulk and most importantly, the angle on the laptop REALLY hurts my wrists... but apparently they won't send out 6-cells as replacements anymore, just 9-cells.
I'm wondering if there's anything I can tell them to get them to send me a 6-cell without having to put my 9-cell on ebay or something .....

I have read guidelines of battery maintenance. It says the best is to keep charge level of the battery at a certain level: 40% for storage, around 80% for standby. I am using same levels for my office laptop Lenovo T400. It is set via Thinkpad Power management utility and works marvelous! Hovewer I was not able to find similar settings in Acer Power management SW. Vista doesn't have that either (as it seems to me ). My main idea is to keep the battery attached and serve as a standby power backup, but minimize charge level to 40%. It is sufficient to protect against short power interruptions or roam around the house from one socket to other.

My laptop is refusing to accept the charger cable so I cannot recharge the battery or power up the laptop. The original charger broke but I have tried a new Dell charger and it will not work.

I'm looking to get the Studio 1555 and the only thing I'm not sure on right now is which battery to get.
Is it true that the 9 cell sticks out the bottom a little bit? I would just go for the 9 cell, but I use my current laptop on my lap a lot and I'm worried that if the battery sticks out the bottom it would be uncomfortable since the laptop would be resting on two points rather than the entire bottom

how do I check how many cells my battery has? Its either 4 or 6, since it doesn't have the external prop behind it.

I have a Dell Inspiron 6000 for about 4 years almost. I have 512MB but am going to buy the 2GB ram from newegg because it is very slow.
I am also formating my laptop as well as my desktop. Most of the time i use my desktop but for my laptop i bought a charger that was CHEAP and i think it messed up my battery life a bit.
I just purchased a new charger from Dell and will throw away the bad charger i have.
My battery life in my 6000 is about 40 minutes. It used to be 2 hours and 30 minutes when i first got it. A few months ago it was actually 1 hour and 20 minutes. My neighbor has a e1505 and his battery lasts like 5 minutes now so all he does is use his charger.
I see on Ebay from reputable sellers that the 6 and 9 cell battery price is pretty close. 6 Cell is about 44 dollars and 9 Cell is about 48 dollars.
6 Cell one

i am having a hard time deciding my configuration for a inspiron 13"
i noticed that the Refurbished laptop have a Great price $609, 2.0 intel core 2 duo,4gb,320gb,6cell,Dell 1395 802.11G Wireless Mini Card.
For that price it seems to good to be truth, but i have no experience with refurbished laptop.
What is causing me confusion is, if i should go for a new laptop that has ,2.0ghz(same cpu), 3gb,250gb,intel next gen wireless N, 9 cell battery
for $779, all because the $10 for the wireless and 70$ for the battery
and it has a 195$ discount already of the original price.

so i know that the 6-cell battery lasts about 1h:50mins just doing light stuff such as web-browsing and word processing(maximum brightness, power saving mode). Anyone have any ideas how long the 9-cell can last while just watching movies??

I recently purchased a refurbished Dell Latitude D630 and everything was great. After a few months the laptop would every so often get a message saying:
"The AC power adapter type cannot be determined. Your system will operate slower and the battery will not charge. Please connect a Dell 65W AC adapter or higher for best system operation."
It was ok after I fiddled with it and it would charge normally. Now the battery refuses to charge with my adapter and runs only on AC power. I assumed I just needed a new battery but then something weird happened. I used my girlfriends charger to charge my battery and it worked 2 times, but strangely after the last time her computer started getting the exact same message and hers was fine beforehand. Is the battery somehow draining the adapters? I've never heard of that happening before. What should I do?

HP notebook I have ever owned. Given I'll be taking this to school under the elements, how long on average can I see this GPU lasting? And if it dies under warranty, will HP fix it for sure?

I have a DV7-1023 that is less than a month old. I finally got around to burning some dvd movies from files I copied to the local hard drive. The total process time to burn a movie from start to finish takes 23 minutes at 8x speed.
On my old laptop the process time from start to finish took about 15 minutes at 6x speed.
The machine has the vista 64bit version that came with laptop. I am using Nero version 7.
Is there anything I can do to speed up my burn time?
There are no other apps running, and I tried burning right after rebooting.

I 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?

my gf and I went out and purchased the HP G60-126ca laptops to only return them a few days later due to their incredibly short battery life.
I took the serial number into work(I work at HP) and ran the serial number to find out that the 6-cell battery was 2200mAh which would equal about 1 hour 30 or so min.
Now I'm about to order a dell but looking at some other higher priced HP laptops I was wondering what the battery life on some of them can be? or if any of you have some of these notebooks.
I can't run them in the system because I need a serial number to get the battery information, or else I'd do this at work
Does anybody here have any of the following notebooks?
HP Pavilion dv5-1140us Entertainment Notebook PC
HP Pavilion dv5-1250us
HP Pavilion dv5-1159se Special Edition Notebook PC
I'm just wondering what the mAh is of these 6-cell battery's. (I work for desktop support so I don't have too much access to the detailed laptop information unles I have serial numbers)

My year old 12-cell HP extended battery for my dv6870 is draining really fast. In 10 minutes it went from 100% down to 70% and all I am doing is browsing. Is the battery shot or is there anything I can do to save it?
UPDATE: From 100% to 7% in 25 minutes. It used to last 2-3 hours!

The DV5T is one of two notebooks that I'm considering and I have a question related to the heat while gaming. Many have recommended a cooling pad, and many also suggest simply raising the notebook .5-1" in the back. With the natural lift of the 12 cell battery, would the cooling pad still be necessary for long gaming runs? I don't want to pay the extra $20 for the 12 cell only for minimal cooling gains and still needing to buy a cooling pad. Or is it cooling pads are highly recommending for all laptops when gaming?

I have an HP Pavillion dv6040 laptop, 3 years old. Today, after 3 years of nearly flawless operation, it will not start. It gives 1 long and 2 short beeps, and then nothing. The lights turn on, the fans run, but the screen remains off (black with the backlight off).
I believe it is a video problem (looked up the beeps online). The laptop has an Nvidia GeForce 7200 Graphics card.
Or does anyone know if it's possible to replace the video card in such a laptop?

I am buying a dv5t off ebay but none of the laptops on there come wit the high capacity 6 cell battery offered on HP's website. Is there any place I can buy one? I've tried ebay but it doesn't appear there are any on there.
Also, model number or serialnumber for the high capacity 6 cell so I can check online for it that way.

I have 2 extra high capacity 6-cells (compatible with dv4, dv5, and several other compaq models) that i don't need because hp will be sending me my replacement dv7 soon and they dont fit. i want to sell them but i don't even know what a good asking price would be(hp does not even sell them individually on their website). they've been sitting in my fridge for the last month and have hardly ever been used, one of them i believe is still 100% capacity.

to prolonging my 6-cell high capacity battery that just came with my dv4t? My previous laptop which was a Sony Vaio(purchased new in Jun of 08) had a battery life of two hours. In December of 08, it all of a sudden only was able to last 50 minutes, and this became a huge problem. Are there any tips for prolonging a battery's full life as much as possible?

I've been looking at the 12 cell battery to go along with my dv5t for the extra battery life. I know that the 12 cells battery raises the back part of the dv5t up quite some bit. Would that negate or 'contradict' the use of the colling fan (Zalman NC1000). Since the battery pack is elevate, the full laptop wouldn't be able to make contact with the cooling fan, correct?

On the HP site the 2140 is listed to have a higher resolution screen coming soon. Does anyone know when this is? I thought it was supposed to be sometime in February, then March and now the last I read was April 1 but it looks like it's still coming soon.
Also does anyone have the extended 6 cell battery? From pictures it looks like it sticks out at a 90 degree angle to the body. When I saw it I thought it was incredibly dumb. That seems like it would affect portability a lot.

While I was almost a 100% certain my next laptop would be the asus ul30jc, I just saw the folowing laptop in a local advertisement and I must say i'm tempted (being a student, I use almost all of my free money on vacation, food and alcohol so every saved € counts):
Compaq Mini 311c
Intel Atam N270 (1.6ghz)
1 GB RAM
160 GB HDD
Nvidia ION LE (shared memory)
Wifi b/g
Windows XP home (service pack3)
Battery info unknown, though most sites say it has a 6 cell battery.
359€
So I have a few questions. First and most importent of all, I need to know how long the battery will last, if its +7 hours i'm content.
Second, I have no idea what kind of wifi I need, I use that white Belgacom Digital TV Router so perhaps my fellow Belgians can help me on this? When I use system information it says my wifi in my current laptop is A/G/N.
Third, will I be able to install the newest microsoft office programs (I have 2003, 2007 and will most likely buy 2010 aswell) on windows xp home?
Last but not least, will I see a big difference if I upgrade from 1gb of 2gb of ram? I noticed a big difference on my current laptop when I upgraded my ram, but since that hp compac has a very weak processor, it might be pointless since that cpu might bottleneck the effect?

i have a generic battery being used in a G60-249WM laptop and any time the laptop is left and placed somewhere else while on, such as a table or desk, the battery i believe may be losing contact, as the computer just shuts off. what repair can i do, so that my 12 cell battery will work ? oddly, the genuine 6 cell fits and doesn't cause a poweroff when moved.
there is slight wiggleability with the generic 12 cell. for small, but still.
