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.
I believe you are correct. The reactions given in this article are appropriate to dilute battery acid. At the high concentrations of sulfuric acid in an actual battery, the reactions should involve HSO4- at each electrode. The voltages given may be correct, since they seem to add up to about the correct value. Sandman42 74.192.217.168 13:55, 24 June 2007 (UTC)[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)
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 :). Matt B. 11:29, 28 August 2006 (UTC)[reply]
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]
It seems like a perfect match.
Further comment re different types of lead acid batteries:
I accessed this article to learn the difference between a deep cycle battery vs a traction battery. In terms of usefulness of this article, I think the different "design styles" of lead acid batteries should be listed - Starter, Marine, Deep Cycle, Traction, etc, and the differences and specific applications discussed. CofE001 02:53, 26 January 2007 (UTC)
There are many types of batteries technologies that fill this in. Yes all sizeable batteries have vents, but would you please turn over your car battery and see the result :) acid everywhere! SO THE VALVES MATTER PER APPLICATION. The first main distinction is sealed or not (aka can you EVER take the lid off of it!) Next is voltage, plate thickness, construction methods, etc. some are distinct to a few distributors, patented, etc. Some are general and anyone can build em. Should you make the move to a more defined criteria list you are in danger of giving companies spaces. Throw them all together and you can't tell the difference when you don't know better. IS WIKIPEDIA GOING TO BE AN Encyclopedia Based Directory with examples of it's own? THEN WE NEED THE SPACE. I say leave em alone and maybe even add a section where you put batteries together by manufacturer or application. The Manufacturers can't do this as each only has a brand or two, but we can (GOOGLE PRECEDENT). Bigger is Better, CONTENT IS WHAT MAKES THIS POWERFUL. Mukster 14:46, 10 March 2007 (UTC)[reply]
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."

Internationally - Maybe. In the United States, Definitely Not! The lead-acid battery gains its environmental edge from its closed-loop life cycle. The typical new lead-acid battery contains 60% to 80% (sometimes 90%+) recycled lead and plastic. When a spent battery is collected, it is sent to a permitted recycler where, under strict environmental regulations, the lead and plastic are reclaimed and sent to a new battery manufacturer. The recycling cycle goes on indefinitely. That means the lead and plastic in the lead-acid battery in your car, truck, boat or motorcycle have been - and will continue to be -- recycled many, many times. This makes lead-acid battery disposal extremely successful from both environmental and cost perspectives.
BCI, Battery Council International, is the lead acid battery industry group in charge of industry standards. They have acted as a leader, actively promoting the recycling of spent lead-acid batteries and the use of recycled materials in the production of new batteries. As such the organization collects statistical data to provide the annual recycling rate of lead-acid batteries. BCI also developed model battery recycling legislation at both the state and federal levels in the U.S., as a way to efficiently recover valuable resources and keep recyclable materials out of the waste stream. The model has been adopted by legislatures in 37 states across the country.

The reaction shows that Lead Dioxide is on the Negative side, but later is says "The positive plates gradually turn the chocolate brown colour of Lead Dioxide" What's the deal?
"An odd number of plates is always used, with one more negative plate than positive." If there are 6 cells in series, how can this be true? --G N Frykman 08:49, 12 February 2007 (UTC)[reply]
Each cell consists of alternating plates tied together to increase the surface area. K4ZL 11:53, 18 February 2007 (UTC)[reply]
Add voltage to the system So 1 cell is a 1.9-2.4 volt battery sold as a 2 volt model. 3 Cells constitutes a 6 volt battery, and so on.
Add amperage (sometimes referred to as current) to the system. So 3 cells in parallel are still at 2.1- 2.4 volts, but have 3x amperage.
Each 12 volt 50 watt lightbulb needs 4.2 amps to light them up. 50w/12v=4.2a
composition (acid, gel, li-ion), cell structure (# and configuration of cells), and resources (weight, size, lifespan). The best batteries engineer specific compromises between these elements to produce power.
I was a battery design engineer and we had even number plate designs as did every US Manufacturer.
Each cell contains (in the charged state) electrodes of lead metal (Pb) and lead (IV) oxide (PbO2) in an electrolyte
seems like it would make more sense as:

I have added a section on the problem of exploding batteries to address the issues already raised. I work in forensic engineering, and dealt with a recent problem where a mechanic lost an eye through lifting an old battery from a car. I am posting the section because it is an unusual hazard that users should know about so as to prevent possible future problems. Peterlewis 16:37, 20 May 2007 (UTC)
Can a jolt cause a spark to jump between the terminals? Is this different from normal sparks from static electricity on people's clothing? Kallog 07:44, 9 November 2007 (UTC)[reply]
It seems a bit odd to me, static electricity shouldn't be able to build up inside a battery, nor should anything else cause a spark inside, perhaps if you short out or mistreat the battery in a similar way, it would case enough heat to set of an explosion. I suspect the most likely scenario would be that the casing simply exploded because of the built up pressure inside the battery. Batteries exploding is probably extremely rare, would be nice to see some statistics. --Apis O-tang 03:01, 10 November 2007 (UTC) —Preceding unsigned comment added by Apis O-tang (talk • contribs)

I think a typo crept into the article under the heading "electrochemistry." Flooded cells typically require the highest charging voltages, gel cells the lowest, AGM somewhere in between.

This reads like a novel. Battery "progress" is ongoing and a continuous process. There are no "current attempts" Furthermore there is no such thing as a nickel-manganese battery, if there is i'd like to get some, they should be much cheaper and more friendly than NiCd/NiMH.
reverted back to my edit on july 5th, language may be coarse but the difference is critical. I would like to point out that the original change from ni-mh to nickle-manganese about a year ago was also dubious, and has no reference. Unit cost of nickel is a mute point, it may be 10 times more expensive than lead, but its mass is 1/4 and furthermore the ratio of active material to total plate mass, there is no comparison. NiCd is expensive for just about every reason from the case, to the electrolyte to the cadmium, not the high price of nickel, also note that wikipedia doesn't have a $/Wh listed for NiCd —Preceding unsigned comment added by 75.178.85.76 (talk) 23:19, 9 July 2009 (UTC)[reply]
Why are there only reactions for the recharging of the battery but not the spontaneous reactions which produce voltages (i.e. the actual function of the battery)? I think there should be both.--Welcome to the dark side. (talk) 23:28, 8 August 2009 (UTC)[reply]
