Easy to use battery tester to make sure you don’t throw away batteries unnecessarily and especially useful if you use a lot of rechargeable batteries. When you fit multiple AA or AAA batteries in devices, when the device stops working often only 50% of the batteries have drained. Saves money and the environment!

Easy to use and works very well

Work well but think the contacts when you push the battery in will break easy if you don't handle with care.

Great unit so easy to get on with it no more getting rid of batterysThat still have life in them

Great little gadget, checked all my batteries in no time. Definitely recommend...

I bought this product to test watch batteries and I do this quite often as an enthusiast. It is very quick and simple to use and the best one I've had so far. This tester is perfect for what I got it for and would be perfect for other situations too.Sick of throwing out batteries that have been collected in a drawer? Get one of these!Not sure how much power a rechargable battery has left? Get one of these!Great to have in any home and it will save you money in the long term. This product takes 1xAAA battery to power it and is about the size of a calculator.I cannot recommend this product enough, I love it

Compact and easy to use, works perfectly thank you

It does not charge CR2 batteries as the space between the positive and the negative poles is not short enough.
