What does battery DCH mean?

[AedanC]

Hello,

I'm trying to understand some battery characteristics to help a friend with a problem he's having. I've some across the term DCH in the specs of the particular battery he is using but I can't find a definition of it anywhere, does anyone know what DCH stands for?

The battery brochure is attached if you want to see it in context.

Thanks in advance,

Aedan

Discharge

[StuM]

DisCHarge.

i.e. in the specs shown.

If discharged at the 5 hour rate, the battery will reach a 60% Depth of Discharge (DOD) when the "End of Discharge Voltage" = 1.98V and this will be after 3 hours ("Effective Discharge Time").

Obvious really, why didn't I see that?

Thanks to you both for sorting me out.

It really is a completely unnecessary abreviation. They could have recycled some letters from an old PDF and reused them here if they were concerned about ink.

That's a pet peeve of mine. When they use an abbreviation like that, they should at least put a key at the bottom of the page so you can figure out what they are talking about.

If I'm writing a sentence, I try to spell it out fully with the abbreviation in parentheses the first time I use it. This is what Stu did in post three and we all knew he wasn't talking about the Department of Defence.

Later you can just use the abbreviation and everyone should know what you mean.

So, HopCar doesn't refer to a special train car used for transporting hops for brewing?

There is actually a story that goes with that. Back in the day of radio telegraphers on ships, they worked for the Marconi Wireless Service. The shipping companies would contract with Marconi for their service.

When someone on a ship wanted to send my Grandfather's company, Hopkins-Carter a telegraph, the Marconi people would address it to hopcar and the receiver would know it was for Hopkins-Carter Co. in Miami.

I won't say what Hellosailor brings to mind.

DCH . . . Don't Come Home? . . . like if you're inebriated

HopCar-
Actually, when telegrams did exist, Western Union charged the sender by the "word". Also known as the "Western Union word" because WU defined that as five characters plus one space, or six characters counting the spaces. So by addressing telegrams to "HopCar, Miami FL" instead of "Hopkins-Carter Marine Supplies & Fishing Tackle, Miami, Florida" they could save about 3/4 of the cost for just that portion of the telegram.
The creative use of abbreviations, to save money, and the use of commercial codes, to keep competitors from knowing about prices, arrivals, etc., was quite normal in telegraphy.
Which also ties into typewriters and how authors were generally paid. A normal type line was always 60 characters wide, a convenient ten words per line, and that's what you got billed or paid for, except for some publishers who actually counted WORDS and paid their authors based on that. More short words, higher payment.(G)

I write a lot of specs in work and I really try hard not to use abbreviations unless they are really clear. If they must be used then a glossary is a good idea. Defining them the first time is good for the guys who are reading the spec end to end but not so good for the person trying to reference just one section.

I don't think I would abbreviate Discharge to DCH anyway......

I am in Australia. I find it difficult to read many of the posts because of the frequent use of abbreviations used my people from the United States Of America (USA).

At least I can read most of the posts here, unlike a lot of post on other sites, especially Facebook and Twitter and SMS text messages by today's youff.

Amazing the amount of information on this site. Today I've learnt that Western Union used to be more than a money mover. Please keep up the history lessons, they are intriguing.

"BTW" it brings me back to a sign above the bar in a remote Scottish pub where they filmed the beach scenes for the movie Local Hero. The sign simply said "WYBMABIITY" so after a few nips I asked the bartender what it meant. She said "Will you by me a beer if I tell you" to which I agreed then she said that's what it meant. So I guess the bartenders there get lots of free beers!

However the correct response to WYBMABIITY is DILLIGAF
