Talk:Deep-cycle battery

message: Hey folks. Since this is an energy-page, how about we talk about environmental impacts of proper and improper use and disposal of these things? I came across this as I was reading up on Earthships, I may come back when I feel like learning about batteries, but if someone knows stuff ahead of me please contribute.

: No. Different internal construction, thicker plates. --Wtshymanski (talk) 18:32, 20 March 2010 (UTC)

message: I would like to know more about the level of discharge - i.e. discharged to 30%, 50%, 100% of its capacity ? What is a common/normal ?
To what voltage does it drop, in comparison with a normal battery?
: the answer is always "It depends". Depth of discharge depends on the application.  The terminal voltage of a lead-acid battery is not strongly correlated to its state of charge, so it's usual to measure the electrolyte specific gravity to accurately assess the state of charge. --Wtshymanski (talk) 18:32, 20 March 2010 (UTC)

message: Reading the sources I don't see why the first sentence in the article is "A deep-cycle battery is a lead-acid battery designed to be regularly deeply discharged using most of its capacity." From what I'm reading it has nothing to do with the fact that it is lead acid and more to do with its ability to be drained almost completely. Shouldn't lead-acid be omitted from a lot of these paragraphs? I plan on removing the specification that deep cycle batteries are lead acid batteries specifically unless someone tells me otherwise.Learncraft (talk) 01:19, 13 May 2018 (UTC)
replies: text: Because only lead-acid batteries are usually described as "deep cycle" ?  Batteries with other chemistries aren't called by this name even if they are optimized for high discharge. --Wtshymanski (talk) 16:21, 13 May 2018 (UTC)
replies: text:  Addressed, but probably best to keep the main focus here on lead-acid. - Snori (talk) 04:27, 7 January 2019 (UTC)
thread_title:  Why does this article say that its a lead-acid specifically? 

message: A true deep cycle differs from a typical  UPS battery with "thin plates" and lower internal resistance and is NOT suitable for UPS float service. They are designed with "thick plates" and to be (deep)cycled and not continiously to be floated like in a typical UPS Standby application.
Under "Application" is it not better to remove all  description with UPS.  I took few days ago the freedom to remove it but the removal has been activated again. 
Please advise.
