I was worried about placing this order as people say it's not original etc but I toke my changes and time to buy it. Was getting fed up having to charge the battery overnight without any recordings throughout the night. At least I have a spare I can pop in when the battery is drained.
I was surprised with the quick dispatch. I placed the order at around 10.00/11.00am (UK time) and I requested next day delivery (prime) but to my surprise it came later in the late afternoon ON THE SAME DAY! was surprised and shocked!
Then came the moment of truth fingers and toes crossed, hoping for it to be original, and to my surprise it actually was!! (See pictures) the back of the battery is slightly different. But you have to consider new standards, new ways to make it etc.
Put it on charge and you get both lights, and it toke the same amount of time as my old one, then when charged green light stays and the orange light goes.
Made sure my screw fits and it does, and I then placed it inside the doorbell and works great and so far no problems at all!
Overall happy customer, happy product and thankful for Amazon!
