Charge and discharge cycles

Go to solution Solved by Mira Yurizaki,

Every time you do a deep discharge on a lithium type battery, you lose a bit of capacity (among other factors but this is one of them). After 500 cycles, the capacity is going to be at a point where the battery is considered no longer useful. That doesn't mean it won't hold a charge, but it means more like it can only store 50% of what it could brand new or something like that.

 

I don't know what the real value is, but that's what it means.

Anyone have a good explanation of charge and recharge cycles, I've read that my laptop "Alienware 15 R3" has 500 or so cycles. I understand that its when the battery is used until dead then recharged, but what happens after 500 cycles?

After 500 it immediately dies. 

 

Or it just loses some capacity.

Its not as bad as that. probably 70-80% of original if battery is of good quality. At 672 cycles my iPhone 4S battery is at 75% but is now getting unstable.
