Solar trickle charger fail!
It's a 10W solar trickle charger. Found my dual battery down to 9.6V and can't operate my powered jack. Good I have my spare battery, for my kayak motor, that saved the day. My 100W Renogy so...

Many of us have discharged a battery till it was dead , and then only got another 3 or 4 years out of them . I would not replace that batt with out giving it an honest trial .
Really depends, you can get away with most anything if you really don't mind the lights going out before you want them to or the furnace shutting down in the middle of a cold night or say the water pump and lights in the middle of your nice hot bath.
In a auto, you might be able to get away with a weakened damaged battery for a while in good warm weather but come a cold zero day and you will come up with blanks on starting.
At 9.6V that battery is well below ever being fully recovered, if you could get a charger on it immediately it most likely would recover SOME, but would it be enough to camp on for a an hr, a day, a weekend, or so? At 10.5V the battery starts heavily sulfating of the plates, it is near impossible to reverse this effect and ever minute it is left at that state reduces the hopes of recovery and capacity.
If it is standard Group24 or Group 27, they are dirt cheap to replace, $60 for a group24 and what maybe $70 for a group 27.. That isn't going to break anyone's bank to make the system whole again..
Once the battery has been replaced the OP should be able to get 9, 10, 11, 12 yrs if treated properly. THEN TREAT IT BETTER by making sure the battery is being charged or the battery is disconnected from the RV when being stored! In other words, don't do what you did before!
