This is the best way to preserve our environment, using products like this of excellent quallity.
I plan on buying more when the price drops further. They are good batteries, i still have them except i had to buy extra ones last week because i use the old ones for my recorder and remote as well as my TI-83 calculator and i'm getting tired of swtiching batteries between those three items. I usually recharge them when my recorder shows a single bar or 2 left.
I used the recorder for lectures and other stuff as well as a speech lesson i was taking. In terms of using them for back to back 2hr lectures, i think they last for at more than 12hrs of recording. I bought this in December 2007 for less than $10 bucks here and i used them for my sony digital voice recorder.
i usually recharge at the end of the school week. They really are worth it I'll say they do take about 4hrs to charge, and it holds the charge pretty well.
I think when i started for my voice recorder, they'll hold a charge for a week or so.
I was hoping it would double the time between recharging. Perhaps the phone has a high power draw and it just isn't going to last more than a couple of days regardless of the capacity of the batteries available in AAA size. I bought these batteries to replace the rechargeable batteries that came in a Panasonic Cordless phone. They don't last much better than the originals.
They last about half as long as the Alkaline batteries would last. The batteries did not last very long. I was not impressed at all given these are brand new and fully charged. I bought these AAA batteries for use in electric toothbrush. The toothbrush takes 2 batteries.
They keep a charge and get the job done, just what I was looking for. I usually do not like sony products (just a personal preference) but I bought these Sony AAA batteries and have been satisfied since I have the AA's and they work great.
