But so so many wildflowers and heady spring air.
Dd the extended version of my bike route and wow, I was not ready for that after not biking this winter! Those hills in the middle thrashed me.
Went back and looked at the pictures of your battery, and it does not look to be flooded, probably sealed lead acid. Which eliminates the risk it ran out of water, but also no internal access makes it harder to find out what went wrong or do some tricks to recover it. A battery charger is probably the only chance..
If the battery is flooded lead acid, you should first check the water level, adding distilled water if the level is low. Also, you may be able to see if the battery plates are damaged while you have the caps off to check the water level.
Recovering these is much like a car battery; a deep cycle battery is fundamentally the same just made more robustly (and perhaps being 6 volts rather than 12 volts if it's a golf cart style). A higher than usual charge may be able to recover it, at least some of the way. Find someone with a battery charger (maybe a mechanic or garage) that can do a desulphation charge.
