Talk:Lead-acid battery: Difference between revisions

Hey, my professor recently showed us the anode half reaction for this battery and SO4-, according to him, is supposed to be HSO4-, which deprotonates into SO4 2- and H+ with 2 electrons given up. This makes much more sense, since SO4 2- is the correct form of sulfate, and lead would rather have a 2+ oxidation anyway. It's an image, so i don't know how to fix it.

Can we have a good primary source reference that lead is actually recycled? (It seems believable, considering how easy lead is to handle and refine, but you never know). --njh 05:42, 3 March 2006 (UTC)[reply]

MikeC195607:49, 09 September 2006 (UTC) The opening of the article states "Lead-acid batteries, invented in 1859 by French physicist Gaston Planté, are the oldest type of galvanic cell and are the most commonly used rechargeable batteries today.[Citation Needed] Well information for this statement may be found at Encyclopedia Britannica http://www.britannica.com/ebi/article-197275[reply]

Can somebody give a list of how PBAs are charged? (unsigned comment from anon)

BCI would have this information.

I'd love to see some sort of introduction to rechargable batteries for the hobbiest. Of the common types (PbA, NiMH, NiCd, & Li+), I'm not sure which is the easiest to charge - i.e., most resilient to 'dumb' charging from a solar cell, generator, etc. (Unsigned comment by 70.23.244.12. 02:58, 17 August 2006, UTC)

Some of that information is in the Rechargeable battery page (which is hurting for more information and a good review at the moment). Of course, Wikipedia is not an instruction manual, but I imagine quite a bit more could be said on that page. For your own edification, there are battery charging ICs that you can buy that take care of safely charging many different chemistries for under 10 bucks. The 'dumbest' batteries are indeed lead acids (in my experience), while the newer batteries need more complex control circuitry (like the Lithiums that are always exploding in laptops). But you do need to be careful designing charging circuitry for any chemistry. (Please remember to sign your talk pages). Matt B. 23:41, 30 August 2006 (UTC)[reply]

The battery University site has good info on recharging PBAs. The link is already on the rechargable battery page. <http://www.batteryuniversity.com/index.htm>. Dan Oetting 15:03, 28 October 2006 (UTC)[reply]

I'm going to get started on cleaning up some of the existing sections of this article. However, it seems to me that Gel Battery, Absorbent glass mat and VRLA would fit much better into a "Types of Lead-Acid Batteries" subsection here. I'm going to add {{mergeinto}} tags to each of the articles, but I would imagine discussion would be most helpful here since it should be an all-or-nothing kind of thing -- it wouldn't be very productive if just one article moved :).

Agreed in principle. But VRLA (Valve Regulated Lead Acid) is a wider class than the other two, ie it is usual to have a VRLA gel battery or a VRLA AGM battery. Gel and AGM describe the electrolyte status, VRLA is just a safety valve to avoid gas build up in a sealed container. But I'm no expert. Zarautz 20:16, 30 August 2006 (UTC)[reply]

Yeah, the way I worded it makes it sound like they are three different types. More precisely, I would imagine that Gel Battery and AGM would be subtopics of VRLA, which would be in a section under types of lead acid batteries (along with the old-fashioned wet version). I suppose theoretically you could make a Gel or AGM battery that isn't valve regulated, but I've never heard of such a beast (nor could I fathom a rationale for doing so).

It seems like a perfect match.

In the Enviromental Cleanup Section:

The article mentions that new versions of recycling are needed to cut down on polution. Does anyone know exactly how poluting current Recycling programs are?

Also, that whole section doesn't sound very professional.

"Effective Lead pollution control system is a necessity for sustainable environment. There is a continuous improvement in battery recycling plants and furnace designs for greater efficiencies. These recycling plants are ecology friendly as they follow all emission standards for lead smelters, but new methods should be devised or alternatives developed to the lead-acid battery so that lead pollution can be reduced to an essentially negligible amount."

Sounds alittle one-sided...
