*How To Work Out How Long To Charge Your Batteries For!!!*

**Some stuff for the not so mathmatical people:**

A "/" is a "divide" sign.

A "*" is a "multiplication" sign.

1A = 1000mAh

**The Equation:**

A = Batteries Capacity in mAh

B = Chargers Output Currant

C = 60 Minutes (1 hour, pretty simple, eh?)

*A / B * C = Amount of time to charge your battery*

I have a 3.3A (3300mAh) battery, and a charger that charges at 5A (5000mAh).

**This is how I would work it out:**

3300 / 5000 * 60

**What I would key into a calculator:**

3300 "divide sign" 5000 "multiplication sign" 60

And 100% of the time, the answer it will give me is 39.6 minutes.

**Time needed to charge common mAh batteries:**
