New Targus 2200 mAh LSD AA's at Target

[mikekoz]

I picked up a 4 pack of these today at Target. They had them on sale for $11.04......



I figured I would give them a shot. I have not seen LSD's with this capacity. I am not sure who the parent company is, but they are made in China. They were in the digital camera accessory area, not with the other batteries. Has anybody else seen or tried these, or know anything about them??

Re: New Targus LSD AA's at Target

Hey Mike
A few years ago I bought a Targus charger that came with
4 AA Targus NiMh batteries labeled as 2700mA capacity!
-not LSD type- Also they noticeably weighed less than
other NiMh cells-

I experienced about half that capacity.
Was not the chargers fault which I liked and still works
The cells are still fine also with about the same
half the "advertised" capacity.

Just my experience when dealing with Targus.

I also have some of those 2700 mAh cells. I got them with a charger at Target on closeout about a month ago. They seem to weigh as much as my Duracell 2650's, but it is hard to tell. How can you actually measure mAh rating on a battery?

A simple way that gives a rough answer.

(Note : a bit like mpg for a car, Full throttle drain of a battery gives poor yield)

1 charge the cell up.
2 let it rest for 1/2 hour (weird but a standard part of the test)
3 place the cell into a battery holder and connect a resistor across it
and start a timer. Beware small resistor and high currents = smoke.

4 For fun measure the current with a meter and then the voltage across
resistor. use Ohms law: volts = current X resistance. See if it checks out
with the math. 1100mA in 2 hours would be perfect but unlikely.

5.With the timer running keep checking the voltage of the cell as it drains.
When it reaches about 0.9volts under this load that's considered empty.
Going lower will damage the chemicals inside.
Note the time.

Hint\\ a cup of water with salt added to it can work as a safe resistor
to dissipate the heat of a high current discharge test.

My Targus 2700 cells got about 1800 mAh when measured. But they also were at 0.00 mV out of the packaging, so I assumed they might have been damaged by that. I think they may have been discharged by the charger since there was no plastic insulation between the batteries and the charger terminals.

Judging by the lack of responses to this post, these batteries must not be very good quality. I am just going to return them and get some of the Duracells I have a rain check for (For $6.45!!).
