How much was it ???
#5
Hi,these are OK,if used,say on Mouse battery etc etc.You get used to what they shown,i use one regularly.Use a multimeter as well & that can't tell you the whole story.Just volt drop,but this is more easy to understand for most peeps.
No good for saying how much charge exactly there is left in the battery,but most wont use them for that,just should i put in new batteries.Or start checking Drivers,OS etc etc,if to do with PC items.
Ain't seen them in Poundland's near me for ages.But good luck.


Cheers BOB

also available in 99p stores for...

I've had one of these for years and they're perfectly fine for the price for everyday use. Considering this is a delivered price and you dont have to make a trip and park your car to go to Poundland then its not a bad deal for a small and compact occasional use tester.

Regarding the power drop after testing, I'd recommend you test it two or three times to make sure of the reading. Depends on many factors as to why the power drops after testing, and not necessarily the testers bad reading.

have ordered thanks
#9
Bought this from Poundland several years ago.
#10
yeah i can't believe they still make this design, i've had the exact same one for at least 15 years :)
#11
They are not too bad, def not worth 4.99 though. Not all batteries are equal , you usually get one go flat in a device that uses four, so these help you detect it and carry on using the old ones, must have thrown loads of good ones out in the past.
#12
I have one from the poundstore - works fine for me. Very quick way to check whether a batteries dead or not. Obviously you're not going to get super accurate readings, but does the job for me - use it tons - not bad for £1.

No you don't - not if the batteries are all from the same batch. They all get discharged equally.
#14
went for this - thanks
#15
7 day shop now free delivery but prices are higher
#16
I find this very useful.
Got it from Poundland, and it's also in the 99p shop.

In theory perhaps,but not always true,many times in a remote control 1 battery is flat and the other shows a charge.
#18
I bet the residual charge is minimal, though, and the amount you save is insignificant.
#19
We'll *I* find mine useful. At the very least if it show that the battery is flat you *know* it really is flat.
#20
Jumpingphil
Can anyone tell me when they use this thing.
What has made you use it in the first place.
And has it made any difference to your descision to change the batteries or not.


When you find a couple of batteries in the drawer,or want to test your rechargables that are hanging around,then,this tester is very useful,and found in 99p shops.
#21
Oh FFS, what a load of whingers

"These are no good", "These arn't accurate" ..... jeeeezus .... how are batteries supposed to be checked? Keep puting them in and out of various items? Buy a Fluke meter and some loading circuitry for **precise** readings of capacity and current draw?

These things tell the difference between a good battery and a dud. They tell you which of your rechargeables needs charging before you take the wrong set out with you.

If you can get them cheaper, fine. If not buy one. Sorted

Not trying to save money,but when you need that elusive extra battery for your tv remote this could be a lifesaver,if you are too fat to work.....................
remember that "famous" quote.........."when i watch tv all day it tires me out and i need a nap" so a job is out of the question.

Ah - but was it a "bargin"? ;-) And anyway, who's to say it wasn't stolen from there? :)

Agreed - my experience too. That's exactly what I use this for. Cost about a fiver yonks ago.

Got this from 7Dayshopping.com ages ago delivered for 99p .....

Oh how I love your comment - just exactly what I was thinking!
#28
Actually, they're pretty accurate if you pay close attention when you read them - the good zone is actually much smaller than it should be, so the smallest differences in the green / yellow zone actually equate to a big difference in the power reserves. The red zone is pointlessly big, once a battery dips into yellow, it's pretty much useless for everything even for IR remote controls.
#29

No you don't - not if the batteries are all from the same batch. They all get discharged equally.


No they don't - I have a Sony 4xAA batt all-in remote with a light-up LCD and there's ALWAYS one battery that goes flat first, while the others are still at around 90%, so there.

These are even worse for rechargeables. They might show that the batteries are good, but, due to the nature of rechargeables, if you stick them in your camera for instance, and you need to use the flash, you might be lucky to get 5 shots fired off.
Ordinary batteries don't fare that much better either for batteries that are near the end of their life.
This thing is useless.
Save your money.


No, it's not useless at all - very handy, you just need to understand how to read it - the smallest difference in the green zone (for instance, the needle being on the first "O" instead of the second "O" in "GOOD") equates to a big difference in the reserves left - as much as 25-30%.
#31
Great deal, ordered and heated added
#32
Jumpingphil
I personally don't think these are any good.
The battery might have enough juice in it to make the needle go to green, but when you put the battery in a toy car, for example, there isn't enough juice left to make it work.


Listen to this man... I have one of these little gizmos and I got it for 99p last year - it's alright but accuracy is a huge issue. Like Jumpingphil said, the battery might make the need jump to green but that doesnt mean a thing when you put it in your digital camera or kids remote control car.

I only rely on it for remote controls since they use very little juice. High drain electronics though - dont waste your time or money on this thing.

What he said.
#34
Hi,you have to use a bit of Nous with these.
Rechargeable are lower voltage(its nearly certain to be measuring voltage) than std,so you have to give a bit of leeway for these ie it will be lower in the green area to start with.

Then say its a mouse or remote control.These will still work well into the Red.
Camera or other device that needs a lot more power.Can struggle even if it drops to bottom of green.
Etc etc.
Old batteries from say a camera or whatever,can still power a mouse etc for ages.
Will test a duff or bad/poorer battery in a batch etc,missed in my other post + prob other things :)

Cheers BOB
#35
I have one of these and they are very useful and reliable.
#36
I bought a similar device for just 105 yen in Japan. These things SHOULD be dirt cheap.
#37
Arrived yesterday, very useful device.
Note even though Green is "good", you should also look out how far it goes on the green. If its on the left side of the green near "low" then its pretty much run out. The good ones are the ones going towards the right side of the green bar.
#38
If only it were that simple. The fact that even such a simple scale is misleading says it all really.
#39
I've never had a battery go right to the end of the green zone.
So long as it's halfway then you're good to go.
Batteries still work in remotes so long as they show halway and up in the red.
