We Bought 12 of these because at 1000mA and for the many dect phones around office and home,it seemed a good idea for 250mA extra current.
They were almost triple the price 6 months ago.
I expected a long term solution to keeping phones up and running longer between recharging.
Within only 6 months and one by one ( on different models of dect phones but the same purchase date ) they started failing to charge.
I thought it was some mistake and put the lot in a charger that tests for bad cells and all 12 of these had become unrechargeable.
It's not as if a DECT phone has a high current drain - So I'd advise avoid,unless we were unlucky with a faulty batch - it's still an expensive mistake.
There's something not right with some of these 1000mA aaa batteries on sale now and have tried another brand,and will update in May 2011.[> update 5/6/2011 - 12 replacement rechargeable energizer 1000mA AAA's are working fine after 7 months]
I have 750mA aaa's from 2 years ago still recharging fine!
I feel strongly that Rechargeable Battery Manufacturers shouldn't simply state capacity but also how many times you can reasonably expect that capacity to be recharged - or it becomes too difficult to find the correct product in a vast range of mumbo jumbo wording of essentially very similar products.
Our chargers are fully NiMH compatible and can adjust for 550,750,1000mA and 2400mA cells.
