Do the math. If a 10AH deep cycle battery is drained to 50% before being fully recharged again, and you can do this for say 500 cycles before it no longer holds a charge, over those 500 cycles you're getting 500 x 10 x 0.5 = 2500AH over its useful life. If you drain the same battery to 20%, you can only do this 250 times before it dies, and over those 250 cycles you're getting 250 x 10 x 0.8 = 2000AH over its useful life, or 20% less total output over its useful life than if drained only to 50%. That's not trivial, but it's also not THAT significant, for most uses, and for most people is worth it just to get some more juice out of them before recharging, depending on the application. It's when you regularly drain much below 20% that you really start to kill the battery prematurely.

"Battery depth of discharge
General rule of thumb: the less your deep cycle battery discharges before recharge, the longer it will last.
Here's an example:
A Sonnenschein Solar Bloc 100 AH Gel Battery discharged to a depth of 70%, i.e. with only 30% or 30 Ah (amp hours) remaining, will have a lifespan of around 1200 cycles, which is quite impressive. However, if it only discharges to 50%, the expected number of cycles skyrockets to around 1700! If a cycle is a day, that adds over 1.25 years to the life of the battery.
Depth of discharge, also known as DOD, shouldn't be any more than 50% in most deep cycle batteries in order to get the best value for money. So if you have a 100 AH battery, consider the cut-off discharge depth being 50 AH."

I've been wanting a deep cycle battery to keep charged up in the garage to use instead. I think at this price point, it's time to pull the trigger. No more worries about running the battery low in the car.
Also, I'm starting to get into controlling electrical circuits with a raspberry Pi. This 12V battery would be great to have on my work bench to power up any type of motor/pump/circuits being controlled by the Pi.
Thanks OP!
