Talk:Nickel–cadmium battery (vented cell type)

message: Nominated this for a GA to get more feedback on how to improve it. I think currently its well written, easily verifiable from any battery literature and broad enough in its scope (treatment of each type of cell structure and plate type is welcome but keep it brief). The article is relatively stable and the edits on it have been improving it. There are images which illustrate the subject but even better could be found or easily taken. All in all, I think the article more than fills the criteria of a GA and certainly deserves the status. --Miikka Raninen (talk) 10:17, 5 July 2008 (UTC)
thread_title:  Good article 

message: Had to add this article since most of the world thinks all NiCd batteries are of the sealed type with all their problems and baggage. --Miikka Raninen 15:37, 9 April 2007 (UTC)
thread_title:  Vented type new to people 

message: User:216.113.24.1 added the following: "One should be very carefull not to charge a NiCd battery with Constant Voltage when it is coming back from a very low state as this opens the door to reverse polarity that can destroy an affected cell."
This sounds very strange to me. Reverse polarity is something that occurs when you discharge cells, not while charging. And a Constant Voltage charge is typically essentially a Constant Current charge at first when charging an empty battery since the powersupply/charging cables limit the current at first. At least aviation NiCd batteries can be charged with initial currents of up to 10CA with no harm done until battery starts to reach full charge. And language like "opens the door to reverse polarity" is in itself bad since it doens't explain anything, even if there exists? some fact supporting such behaviour. This article, unlike the normal NiCd article is very much based on facts from several manufacturer's manuals and general battery chemistry literature. Lets keep the anecdotes elsewhere... --Miikka Raninen (talk) 20:26, 28 February 2008 (UTC)
replies: text: OK, removed this claim as I found no reference to such from battery literature. --Miikka Raninen (talk) 23:29, 19 March 2008 (UTC)
thread_title:  Explanation required 

message: I'm sure I'm not the only one that doesn't recognise the unit CA. Coulomb Amps doesn't seem to make sense as a unit. Please either spell out the words the first time it's mentionned or link to a wikipedia page explaining it. 
The article on battery charger doesn't mention this at all.  It defines C as "This is often denoted as C and signifies a charge or discharge rate equal to the capacity of a battery divided by 1 hour. For example C for a 1600 mAh battery would be 1600 mA (or 1.6 amps)." Is this the same unit?  If so, perhaps these articles should be brought into alignment.

thread_title:  Define CA 

message: It would be nice if someone could say which terminal (positive, negative) is connected to which material (Ni, Cd) I'm also getting a bit confused with the terms "anode" and "cathode": I suspect that they could mean different polarity depending on whether you view the battery as a power source from the outside, or look at the charging process inside... --BjKa (talk) 14:08, 23 July 2012 (UTC)
