Energizer Extreme Rechargeable AAA 800mAh NiMH LR03 1.2v Pack of 4 Batteries

I use these rechargeable batteries for my Gigaset landline phone. I can't say how long they last but they work. Satisfied customer.

Used them for phone. Arrived today 9th Dec.

These batteries surprised me with their long life. I use these for some wireless headphones I have and have them on rotation so that when one pair runs out, I can put in the next. I use these headphones daily for a minimum of 2 hours stretching up to 6 hours. Despite this, I still only find myself swapping the batteries every 3-5 days of use. Ive had this product for a while now and although have noticed a little decrease in total battery power, its not substantial. The recharging of batteries makes them way more practical than going to buy more. Electricity bills may slightly higher but hardly by a notable amount

I think these are quite expensive but they certainly do the job and are easy to recharge. For some reason a lot of devices require 3 but I think you need to recharge at least 2 at a time so all 4 get recharged each time. I don’t think it’s a problem though. I’ve had no problems with these batteries and have no complaints.

Really happy with the price and they were delivered very quickly. Bought a packet for use at home as I realised that old ones in our landline were dead. They wouldn't even last long enough to dial a number. Now we spend hours on the phone calling our families abroad.Few days after getting the first packet we had the same problem with our phones at work, so ordered the second packet. Again, they were delivered within couple of days using the super saver delivery. Very happy with the product and the price.

Rechargeable so saves throwing away batteries

Energizer batteries have now served me well over the last 2 years or so and no noticeable loss in power or charge when used in a professional top of the range camera flashgun (£300+). The 1 hour charger for the energiser batteries is brilliant and does exactly as it should, however the power cable frays and wires get exposed after regular use and packing away etc which eventually leads to failure. This has happened on 2 items now after 18 months or so.

They are batteries and they do what batteries do, bought as replacements for phone batteries, they are the same as the original and so I guess they will last as long as those did which has to be at least 2 years. The main reason for this review is that I was very impressed at the speed of delivery, almost as quick as going to a shop. Ordered at around 5p.m, they arrived following day at noon.
