CELLONIC, Landline Battery, compatible with Siemens Gigaset A415, C430, AS405, CL660HX (1000mAh, 4x 1.2V)

These are my second lot of replacement batteries for my gigaset phone. Recharge quickly and keep charge. Last lot was purchased a couple of years ago, so last we’ll.

Worked well after being charged.

remains charged for long time compared with other batteries

Magic.

When my Gigaset S850H kept turning off when having a longish conversation, I tried swopping other batteries that were the same value and was getting all sorts of flashing red/green lights. So I bit the bullet and sent away for a set of these, which in spite of the awful weather came the next day. Put two in which straight away did the nice chime and no flashing lights. It had a good bit of charge to power the phone. Now the phone will last four days without being returned to the charging dock. Happy with that.

Prompt delivery and fair price.First impressions are fine, with good in-call performance, but too soon to assess Battery Life or Longevity.However, its a modest spend to re-life our three Gigaset handsets!

When charged they have enough power to allow a decent conversation (or waiting for "one of our operators" to talk to you. Haven't marked longevity because I've only had them a short time so cannot assess this, although I see no reason why the manufacturers claim about the number of recharges shouldn't be true.

We purchased these batteries Les than two months ago, last night one of our phones overheated and short circuited. Now we have an unusable phone and needs to be replaced. Thank god we were still awake, this should not happen. The phones are virtually new, So it is not the phone that’s the problem. This is well known elsewhere with this type of battery, feed back is very mixed and I missed the negative points. The risk is to great to ignore, it could cost you your home. Please think carefully when buying these batteries, and let amazon know if you have the same problem.
