Hi, Everybody,

I just want to clarify a definition of terms for

rechargeable batteries.

There is a common term, "Depth Of Discharge" (DOD) for

draining batteries.

If the battery starts out fully charged, and then I run

some lights, and reach a Depth Of Discharge of ten

percent, does that mean:

The charge on the battery has been reduced by 10%,

leaving 90%?

OR

The charge on the battery has been reduced by 90%,

leaving 10%?

Rephrased, does Depth Of Discharge refer to the drained

power, or to the remaining power?

Thanks in advance...

10% used = 10% DOD

Depth of Discharge - The Ahs removed from a cell or

battery expressed as a percentage of the rated capacity. e.g. the

removal of 25 Ah from a fully charged 100 Ah rated battery results in a

25% depth of discharge

I just cannot resist this temptation opening. (It really has nothing to

do with the matter at hand.) But it flashed into my mind. Its an old

Nefoundland phrase that is not used anymore.

"Stay where your too, I'll come where your at".

Which directly to "wait for me"

I told you it has no relation the the question at hand. (Now smile,

please-please-please)

If you start with 100% charge, and use 10%, you have reached 10% DOD.

That is the depth of discharge (not charge) that you have hit. Over 50%

DOD is bad ......
