Product:
Siemens Gigaset 4000 Micro battery (600 mAh 3.6 V)
General:
I was surprised about the choice of batteries; to be honest I did not expect to find a battery for my Siemens DECT telephone. The web site is good and I could easily find what I was looking for. It only took quite a while before I received the battery, but I know the post can take a while in South Africa. When I contacted BatteryUpgrade about the delivery, the follow-up was very good.
About the product:
The battery was the right one, time will tell if it as good as the original one, which lasted for many years. It was well protected in the envelope it was sent in.
