Batteries fit the phone perfectly and restore the phone' s performance. Delivery on time and well packed.

Maybe I got a faulty pair however upon installing in phone it does not power on or start any charge. Checked all the basics. Returned.

Well-priced alternative to branded batteries. Work well in our Siemens Gigaset cordless phones. The original batteries lasted very many years; I'll have to see if these last as long.

Got this to replace original battery in an old phone as it wasn't holding charge. Changed over to new one without any bother and charged it for recommended time and it now gives around 2 days battery life depending on usage. I recommend this battery.The spare one was tested and left to discharge to 70% and pack away as backup.Great item and cheap as chips.

There was nothing to tell you that the two batteries purchased needed to be chargedI have charger the that sort of battery so the purchase to me is worthless

The original batteries in my Siemens Gigaset DECT phones are still going strong apart from one which no longer takes a charge, so I was provided with these to test out. The replacements are the same physical size as original, and with the connection contacts in the right place. The originals were 750mAh whereas these replacements are 900mAh - should help provide longer 'out of charging cradle' life.I did a simple 'run down' comparison of these batteries against one of the 'good' originals - both were fully charged for 24hrs then removed from the charging cradle and left to run down. The original lasted 6 days whilst these replacements lasted for 7.5 days. Unfortunately I don't make outgoing calls that last for hours, so cannot see how long either battery lasts in use on a call, but the run-down test indicates these replacements are as good, if not better, than the originals.
