The depth of discharge of a battery discharge/charge cycle significantly affects the life of the battery.
Here's an example from the specs of a typical 12 volt LiFePO4 battery
- Cycles @ 100% DOD: DOD 2000 Cycles
- Cycles @ 80% DOD: DOD 3000 Cycles
- Cycles @ 50% DOD: DOD 3500 Cycles
- Cycles @ 30% DOD: DOD 8000 Cycles
As you can see the batterys life is much greater with shallow discharge cycles. I don't see how the batterys electronics 'counting' discharge cycles is particularly relevant to anything at all and may just be a marketing/sales gimmick.
