Right,.............charge/discharge.........now your talking about 'cycling' the battery.
Hmmmmmmmmm How to explain this?
Firstly let me tell you that you can discharge at a much higher rate than you charge. So on a 2100mA battery you could safely discharge at 1.5C,...say 3Amps.
Not sure what you do and don't know Cha. So I'll assume that you know nothing, like 'Manuel' in 'Faulty Towers' :lol:
With Nickle-Metal Hydride (Ni-MH) or the older Nickle-Cadmium (Ni - Cd) batteries they have a problem. If they are not fully discharged down to their safe minimum discharge level every so often they tend to "remember" the average discharge level that they've been used to and not hold as many amps as they should :x
Confused? :?:
Think of a bottle of milk :lol: No I'm not joking...think of a bottle of milk that has been emptied, but not rinsed out. The small amount of milk left in the bottle will "turn" after a few days and solidify.
Now supose it's re-filled with milk and then emptied again. (But not rinsed out) The small amount of liquid milk left in the bottle will also solidify.
If this cycle is repeated many times eventually the bottle will no longer hold as much liquid milk as it first did because the inside of the bottle is being filled with solidified milk.
This is an analogy of what happens in Ni-MH and Ni-Cd batteries.
The way to rid the battery of this "memory" (or residual milk) is to discharge the battery down to it's safe discharge state, (rinse the bottle out) and then fully recharge it. This is known as "Cycling" the battery.
So,...........if you just want to charge the battery, that's fine Cha. However it's a good idea every so often to Cycle the battery to get rid of it's memory effect and ensure that it holds all the charge (Amps) that it can.
I cycle my rx batteries about every 20 charges. Okay Cha,........CHA stop snoring!!!
