Re: replacement battery suggestions
survived 2 cycles...
the capacity is now shown as 97.5%... so 2.5% wear...
looks good to me...

Re: replacement battery suggestions
Wouldn't it be more beneficial to change the cells as opposed to buying an entire (and every expensive) battery unit? I've seen people do it, it's not that hard, but it could potentially be dangerous if your wiring is off...

You might as well open up your old battery and try to rebuild it.Comment

Re: replacement battery suggestions
ummm... I already bought the battery... besides, I wanted 9 cells, not 6 cells (the old battery was a 6 cell).
Besides, without special reflashing HW/SW, rebuilding is pointless; the battery controller has to be reset so it shows the battery levels correctly.Last edited by ratdude747; 01-22-2012, 01:31 AM.sigpic

Re: replacement battery suggestions
Another brief update- after 4 cycles, the cpacity has risen to 98.7%, or 2.3% wear. I am getting run times around 4 hours per charge.
IDK about others, but I think I got a good deal...sigpic

Re: replacement battery suggestions
final update:
it has settled at 94.8% capacity, or 5.2% wear.
It gets about 4 hour run times under normal use... granted I do like to use a USB flexlight at night and durign the day I tend to be an LCD brightness hog when sun glare is an issue... but then again, when there is no wifi aces the BT and WLAN get turned off (I tether to my cell phone via usb instead).sigpic

I have had with regular AA batteries that leak this meter is expensive new I already replaced the battery battery clips once and the same thing happened again and I am tried of so it is getting modified to accommodate lithium ion batteries that are the same size excluding the positive terminal and removing the battery clips I will have enough room for the BMS protection board
I going to put 3 lithium ion battery in parallel with the BMS protection board and a way to charge the battery externally and heat shrink the battery pack and use a JST connector so I easily remove the battery... -
I have a cheap action camera with an annoying trait, every time I change batteries the date & time gets reset and I have to set it again.
To solve this problem I want to add a small internal battery inside it which will keep supplying power to the camera for a while while I change batteries so the date & time is retained.
I have opened the camera and I think there is enough room to add something inside to accomplish this:
The camera is powered by a 3.7V nominal single cell lithium ion battery.
So I need to connect another battery in... -
My question pertains to understanding the control circuity inside a Dell PT434 type battery used in Dell E6400, E6410 and other Dell notebooks?
Does anyone have a circuit diagram for the inside of a Dell PT434 battery and/or a description of how the control lines work to control this battery?
My reason for asking is I have a battery which I cannot get to charge beyond 1% in a Dell E6410 or E6400.
The LED bar graph charge indicator on the battery shows one LED lighted when the info button is pressed.
I have tried multiple different Dell power adapters. My Dell... -
Hello guys,
I would like a quite old but still good 800 W ATX PSU to be repaired. The problem was an extremely heavy coil whine coming from the small secondary transfomer on the PCB.
I desoldered it hoping the references on the upper side would allow me to find a adequate replacement part. Sadly the written references drove me nowhere but to the manufacturer (I-MAG). I sent them a message like a bottle in the see asking them to send me a datasheet of the transformer. And... They responded ! I received a kind of datasheet (see attachment) but my competencies do not allow... -
