### ⭐⭐⭐ 







  
  
    Do not beep when running low in smoke detector
  

*by M***N on Reviewed in the United Kingdom on 29 July 2019*

I bought these almost a year ago and thought they would be great because I have 2 smoke detectors so 1 battery for each. Fully charged them both but only used 1 because the other detector had a decent battery still in it. After a load of burnt grease smoke from my oven poured out earlier I wondered how the alarm didn't go off. So I pressed the test button and nothing happened, dead battery. Then I grabbed the other one I had charged and tried that... didn't work either.So for a start, every other battery when running low causes the detector to beep every few minutes until you change it. This one didn't. Then secondly if you charge them and leave them they run out on their own, yes I know batteries do that but I thought it would have held at least a little bit of charge.It was negligent of me to rely on them and not press the test button frequently like I am supposed to (won't be making that mistake any more) I am charging them both again now and will test each week to see how long they last and may update review based on what happens but be warned bout them.

    Fantastic product, fully recommend this
  

*by Y***N on Reviewed in the United Kingdom on 25 January 2019*

I bought a pack of two to use with my TENS machine which I use daily. You should put them on  charge as soon as you get them and it comes with a double headed charging cable but you can also use a Samsung type phone charging cable too as the slot on the battery is exactly the same as Samsung chargers.It took just under two hours to fully charge them, which is amazing if you compare it with regular rechargeable batteries which can take about 8 hours or more. They are so convenient to use as you can charge them anywhere even in the car, laptop etc. One of the best products I have ever bought.

### ⭐⭐⭐⭐⭐ 







  
  
    Excellent rechargeable batteries!
  

*by I***L on Reviewed in the United Kingdom on 30 May 2019*

These rechargeable batteries were a real bargain. They charge quickly and seem to keep their charge quite well. I had bought a pack of two because I was worried I would need a backup but so far I’m using only one of them in a measuring device (so not too demanding, possibly). Each battery comes with a short mini USB cable. I have enough charging cables but since this one so small overall it fits into any small pocket and useful for charging on the go.
