Rechargeable batter life related question
I have been using rechargeable Energizer 2300 mAh AA batteries for the
past 2 years. Now, the batteries don't last much longer in my Canon S1 IS camera. Some times, I get low battery blinker soon after 10 pictures or so. I don't use the LCD much. Is it normal for these kinds of batteries after 2 years of normal use? I read a rechargeable battery review on the Internet where they rated Energizer 2300 mAh batteries on top. I am wondering if I should buy new set of batteries or if there is something wrong with the charger. Thanks for your time. |

I have a lot of bad ones myself. I suggest getting some new batteries. I suggest Sanyo Eneloops. These are being marketed as some kind of new technology that reduces self-discharge, but I think they're just existing technology applied more conservatively instead of trying to reach the limits of capacity. The result (in my theory) is lower capacity, slower self-discharge, and more reliability, similar to the old 1700 mah cells. I haven't found Energizers to have high failure rates unless they aren't treated well, and I've occasionally been guilty of that. I also think that there's a bigger difference between Eneloops and common NiMH cells, and that manufacturers aren't playing the silly reformulation game that they've done for decades with alkalines. It's not just Sanyo that has them. RayOVac calls them Hybrid batteries instead of Eneloops, but both types use NiMH technology. The Eneloop AAs are rated at 2000mah and the Hybrids at 2100mah. Both are packaged fully charged, and the Eneloops include a date code on the package that implies most of the charge will remain even if the batteries remain on the shelf for a couple of years. They pass your theory for lower capacity and slower self discharge by definition. Whether they're more reliable or not I can't say, other than to reiterate that I think that most people's problems with NiMH reliability is not due to the brand, but to the way the NiMH cells were used or unknowingly abused. |

If they're rated similar to Uniross Hybrios (same technology), the Eneloops
are good for 5 years life. "Paul Rubin" wrote in message ... writes: Is it normal for these kinds of batteries after 2 years of normal use?

Does the charger sold by Eveready discharge the batteries prior to recharging them? Almost certainly not. I left a set in the charger for an extended period of time and noticed one day that it was charging when they hadn't been removed. This is almost always bad for NiMH cells. If you did this, it explains why your cells aren't working properly now. |

Battery life - rechargeable or lithium? | Default NG ID | Digital Photography | 16 | August 22nd 06 10:52 PM |
Good morning or good evening depending upon your location. I want to ask you the most important question of your life. Your joy or sorrow for all eternity depends upon your answer.
