hellooooo!

just a confirming quesiton.....

LED, using 25Ma

Is that 25 ma per hour?

or, 25ma per every finite divisionable fraction of time?

.........?

Current and time are in no way related, so your question doesn't mean anything?.

What do you actually want to know?.

say, 800 ma battery, 6 leds on?

Assuming the battery is 800maH (milliamp hours), and you're drawing 25mA from it, then (in theory) it should last 800/25 hours = 32 hours. However, that's in theory, in practice it can vary quite a lot depending on the actual current drawn, and the maH rating of the battery is usually done at the optimal loading, to make the battery look good!.

So only use the maH figure as an indication, but test to see what actually happens!.

Jitsu, as in 'Ju Jitsu', which means 'way', 'technique', 'method' etc.

I added it after great demand for me having an avatar!, I choose this as I'm a 3rd Dan Ju Jitsu instructor.
