"9-cell laptop battery"; is it 9x 18650?

I saw this on Amazon

Are there nine 18650 batteries in one of these? I ordered one because my Vostro 1500 battery finally died, and this seemed like a good deal. If it really has nine 18650’s in it, it would be worth buying some just to tear them down and use the batteries if they are decent. Curious what others have found.

Read the reviews… looks like crapola.

To quote Spock, ‘It is only logical.’

I once broke up a battery pack from a Dell laptop but can’t remember the part number. What I got inside was mustard-yellow
Panasonic CGR18650HG 1800MaH, all 9 of them retaining up 99% of their capacities. Maybe I was just lucky enough to get a batt pack from hardly-used, dropped laptop!

I butchered[skillfully]a packardball easy note.Got 6 x cgr18650cg in them.Ther green.Did a search and ther panasonics

Also these came up,whom i have an order in with at the moment for ther best spec bats.

I have tried them in my sky ray king and ther good.

BRIAN…

That battery pack has 2400 mah batteries in it. Not worth it for me.

Looks like you’re addicted to your Panasonic 3100s… they’ve really raised the standard for you huh?
Well for me, I never run my batteries all the way down, I usually charge them at about 40%, so if they’re 3100s or TF 2400s I don’t really mind. I just bought the 3100s because of some weird paranoia I have of the world ending.

It isn't so much that, but I have a basically unlimited supply of ones with 2600 mah batteries in them. (Albiet used, but they are free)

Just saying, if they are really Panasonics, that’s 3 bucks per battery for a well-known and respected maker.
I’ve been using 2600 Himax’s, but for less than half the cost this would seem to be a great bargain, even if you do have to perform some dismantling to get to them.

And depends on how much time they spent at 100% charge too, the other way to kill lithium batteries

They have spent most of the last 4 years on full charge, all day, 6 days a week. Rarely do I disconnect the power supply from my laptop while at work. But when I need it for a weekend away, I usually have a battery life of 4-6 hours.

This weekend when I turned the laptop on in a hotel, I got a flashing red battery light, and the battery would not charge at all. So I ordered a new 9-cell Dell battery, cost me $27 and free shipping. Seems like a great price for 9 18650’s which is why I started this thread.

Are you going g to break open the dead one to see what’s in there? This new pack would be a great deal if the cells are nice. Pretty cheap price and nine cells instead of six.

The “dead one” is the original Dell battery (which is $139 to replace from Dell)
The new one is some sort of Chinese budget version.

I just ripped open a rarely used ex work Dell Latitude laptop battery and there were 6 green no name 18650s.
3 were nearly empty (disposed of), and 3 had 3.7 volts. Charged them up and they’re holding 4.12, 4.16 and 4.17 after 3 days.
They maybe 2600mAh, the closest I can identify them is

I have another battery pack that’s had a much harder life, always plugged in and used daily at home. It will be interesting to see what condition those cells are in.

I provide desktop support for a large company in my area and we use Dell systems exclusively so I get some failed/defective battery packs from time-to-time. I’ve seen several cases like you are describing, where the laptop shows a defective battery, but the problem is apparently with the charger circuit (maybe?) on the pack. The laptop works fine with a new battery pack, but when I dis-assemble the defective pack, all of the cells will be okay. I try to check all of the packs I can before they hit the disposal bin and have scored some good Sanyo cells and some reasonably decent Samsung cells that way.

I have fixed several packs with this condition. Look around on the battery management circuit board in the battery and see if you can find a pad marked RST (it is usually surrounded by a white circle). It is usually near a similar ground pad. Momentarily connect RST to GND (I use pointy tweezers). This will reset the small processor on the battery management board and may get the battery management board/battery pack working again.

Since when LG Chem is “no name”? :stuck_out_tongue:

Yup, those are LGs all right. Exactly what I got from a Dell pack a couple months ago, but mine are tan. Mine work SUPER. Computer saw the pack as utterly, completely el deado, but when I cracked it, I found only one bad cell. The rest were 3.5 volts. All charged fine and hold a charge better than my xtars and TFFs.

I have been using them for a couple months now and they’re great! As good as panasonic 7600 mah or whatever :wink: ? Probably not, but I get super run times from em and can see no brightness diff between them and any new unprotected 26/28 mah batts I have.

For free, it’s a broken drum …. You can’t beat it!

Those LG cells in the Dell Latitude battery pack- I found another 3 under the wrist rest on the battery pack, so 9 in total. Almost threw that bit out.

I ordered my new (non OEM) Dell battery pack on Saturday from Amazon and it was in my mailbox on Monday afternoon. I’m downright impressed with that. The new one is a perfect match for the OEM, looks like it will be a great deal for $27.

Now to mess with the old one…
