adelemon Posted December 4, 2002 Report Share Posted December 4, 2002 A fairly simple question (I think). If I use an alkaline battery in place of the NiCd battery supplied (alkaline is used for longevity) and accidentally put the player on the charging stand with the supply connected. Is the player clever enough to know that it should not try to charge this battery, or will it try anyway with potentially dangerous results. Do I need to take out the battery when doing lots of recording for safety reasons? Has anyone any experience either way? Adelemon Quote Link to comment Share on other sites More sharing options...
dannn Posted December 5, 2002 Report Share Posted December 5, 2002 my experience is that the player will eventually stop charging but this can damage your unit. the battery can leak and cause major damage to the unit. if this only happened once just make sure it doesnt happen anymore or too often. i think on the 707 as long as it doesnt say "charging" it will be ok. but a cradle will automatically charge it so i would say if you do put it in a cradle you should take it out if you want to keep your 707 for a while.

Mystyler Posted December 5, 2002 Report Share Posted December 5, 2002 I've found that most devices are clever enough to realise that the battery isn't rechargable - and the R700 (not N707) didn't charge while an alkaline was in the battery compartment. Better to be safe than sorry though, and check what battery you are using before you charge. :wink: Quote Link to comment Share on other sites More sharing options...
Bazirker Posted December 5, 2002 Report Share Posted December 5, 2002 I have never ever ever ever ever ever ever had a unit try to charge an alkaline battery for more than like two seconds, and I have 3 (plus other portable cd players) different recorders. I believe that the unit runs current through the battery backwards of what the normal direction of the current is and it charges the battery (physics stuff.) To the best of my knowledge, normal AA alkaline batteries have a potential difference of 1.5V, whereas most rechargables have slightly less than that, 1.2V. I believe that the unit detects there differences in voltage, thus detirmining if it is a rechargable battery or not. Now I don't KNOW that is how it works, but I don't really see another way that it could. By the way, I just went and checked those battery voltages. A standard Duracell Ultra AA is rated 1.5V while my Energizer AccuRechargable Ni-MH batteries have a voltage of 1.2V. Quote Link to comment Share on other sites More sharing options...
