why are there MaH and A on my battery

[J.P.M.]

OK you want the real answer? Pretenders are guessing and muddying the waters. .

mah = milli amp hours. Where the whole number 1 = 1000 mah. or 1 x 10-^3rd power = Milli or 1/1000th. In engineering we use scientific notation is used to express very large and small numbers. In this case makes a tiny battery sound larger.









So 3000 mah = 3 Amp Hours. 3000 mah / 1000 = 3 If you like that then can I sell you some 300,000 micro ah batteries? Or how about a .003 K ah battery. All are the exact same size.

35 is a C-Rate and with lithium 18650 cells means they can be discharged at 35 Amp which roughly translates to to C10 where C = the Amp Hour Rating of the battery. In this case 3 amps x 10 = 30 amps. At 35 amps is C 11.666666666667

So it means 3 amps hours with up to max 35 amp max discharge current , or C10 aka 6 minute rate.

3000 mah sounds like a lot more than 3 ah huh? They are EQUAL. On the flip side I have designed a many 48 volt 40 Kah batteries. Sounds small huh? If you call 115,000 pound battery small. Only Americans get confused by it.

So, for all that explanation you'll get 10 EE-18 boys, which, by my reckoning == 1 "attoboy". Collect 10 EE 18 of those and you'll get an "O boy", the duck will come down and give you 50 bucks and a groupon, which, along with the 50 bucks, is good for a prostrate/balloon knot check from a small fingered Romanian midget with an attitude.

I'm not sure an attoboy is a discrete, quantize-able amount or not. Since EE's are more cerebral than ME's, as may be obvious from this post, I leave that as a question for you to ponder. Just don't say I never gave you anything.

The 3000 mAh is the capacity of the battery. The 35A is a max discharge rate, usually a very short duration. The max continuous current on those batteries is 20A, according to the specs - this rate wouldn't be supported much longer than the 35A though.

They likely aren't 3,000MAH or 3AH, 35A is what you might get in a short circuit. With Li you are buying a dream.

Hi guys, so i'm buying these --- 18650 3000MAH 35A --- Lion batteries to replace my acid batteries, on batteries you would see Mah or AH meaning how many amps in that certain hour, so what does it mean when it says this on a battery ? 18650 3000MAH 35A?
