I always had good luck with Yuasa batteries. Any battery that you "kill" will never be worth it's salt so to speak after that event. As I understand it the lifespan is diminished if it gets to 50% or lower of it's capacity.
I recently installed 6 Lithium Iron Phosphate 100A batteries in the 5th wheel as well as 5-320W solar panels on the roof and a charge controller configured to handle the power. These are not the type that you hear about that catch things on fire like in E cigarettes or the kind that is in a drone/quadcopter. You definitely don't want to disassemble one of those as in punch a hole with a pocket knife like somone I know did.
They will catch fire and you have to throw them out the door........All this to dry camp or boondock as they call it. If you could get a battery in the YTX-14 size made from the same cells it would be much lighter and you can actually take them down to zero and just charge it back up with no damage.
