is it how long a battery can be re-charged or how many times can a battery be re-charged till it's not re-chargeable any more?

Both. It will eventually not hold a charge as long and will get to a point where you can't recharge it. This is usually 1,000s of cycles though.
Why does it matter to you?

say i'm charging a device(the battery inside really), and the normal charge time is 8 hours, if i leave the charging on for 10 hours, am i wasting the charging life of the battery?

Depends on whether the charger is a smart charger or not. Some will stop to prevent overcharging, so the battery is effectively disconnected. OTOH, the cheap solar pathway lights are real good at ruining batteries by overcharging, being black in the hot sun, not being moisture-proof, and so on.

It's not the charger that regulates that, it is the device. And any modern device stops charging at 100%.

charger - as in the charging circuit within the device, not a dedicated charger. I'm curious if you can find a schematic for a solar pathway light chip?

Gotcha. So we're in agreement.

Just curious if those also have a cut-off now. Chips are so cheap that one would think that the overcharging issue has been designed out of them as well. I've not ever seen a schematic for a solar pathway light.

Well, they're all a bit different. Some types of batteries last longer if they're nearly fully discharged before charging, others prefer to be kept "topped up". Find out what kind you have, then read up on it. Google something like "extending life of Li-ion batteries".
