Nursing camera batteries?

In the UK, a decent NiMH low drain rechargeable is about 10x the price of a disposable for say 2000MaH. 1.2V for rechargeable, which affects comparisons - I've not found it an issue in use. Worth it to me, plus the relatively low waste. Although not of much relevance to cameras nowadays ;-) very relevant for grips, flashes, other accessories and even a couple of cameras. |

The explanation is that it allows battery management system in the iPad to recalibrate itself. The explanatikon was minimal and I didn't understand it. Does it make sense, even if only in terms of iPads? it makes sense. what part did you not understand? The part where it contradicts your advice "discharging them fully is a very bad idea... " it doesn't contradict it at all. add that to the list of things you don't understand. So, what practice do you follow? Do you never fully discharge your batteries or do you preiodically fully discharge them? this is not about me. diversion attempt fail. It was not an attempted diversion. It was an attempt to get your advice. which was already given and you obviously did not read. it's also not my advice either, but that of battery technology itself. Never mind ... yep. And the advice of device manufacturers is that for the sake of the battery management it is necessary to run the battery down to zero from time to time. It's not possible to fully reconcile the two requirements. How should this conflict be dealt with? If you are talking about NiMH, Since they do not have memory, you can top them off for everyday purposes. However if you do a deep discharge a d recharge once in a while, it will prolong the life of the batteries. Thanks Peter. I will take your advice on this matter ahead of nospams. -- Regards, Eric Stevens |

Rather like trying to carry on a discussion with you. :-( -- Regards, Eric Stevens |

But my statement was based upon research conducted on NiMH batteries to be used for medical purposes. And yes cycles do cause the cathode to wear down. But a a periodic total refresh increases the life. You can research that for yourself. -- PeterN |

See the paragraph at the head of this article. yep See also your comment which followed. yep What to do? What to do? one thing would be to learn before spewing. ^^this^^ |
