When replacing your batteries with new ones and did you clean your ➕ and ➖ where you insert the new batteries into the battery slots and use a soft rag to rid of battery residue first. If not then your new batteries won't have a good contact because eventually battery residue builds up every time you replaced it with new ones. In the past I used Apple rechargable battery and charged it 100% for a full charge and I use my battery tester and after a full 100% charge it had only 1% charge left in the battery so I took it back to Apple and Apple gave me another set of rechargeable AA batteries the same thing happen again. I took it back and got myself a refund. I've been using AA batteries for everything and the best brand is Duracell guaranteed for 10 years. I used a lot of different batteries and I use a battery tester to see how much charge is left in the batteries when testing it or do I need to buy more batteries. The battery tester can test batteries for instance button cell 1.5V 1mA, AAA, Photo 6V and so on and it is a good tool to have if you use a lot of different types of batteries like I do.
