Assuming they are lithium ion it will say expected recharge cycles. No one counts them but, you get far more charge cycles if you do not drain the battery far down. You should recharge them after each use not wait till the next time you want to use the tool.
Heat, as in your garage is also bad for batteries.

Mostly agree, except you can’t drain them dead. When one stops check volts, they have at least 30% left. At least the ones I use do.
Good luck getting 7 years out of big battery. Imo they have charging cycle limit. The more you overheat them The shorter the life will be.
