Oops. (I think)

One liter,,, Across six cells, no, that is all that much,, If the boil off is equal across all six cells they can take between 3 and 4 liters,

Though with the quick fill system that may be reduced a bit but you are still less than half way to "Worried".

L-16's are a heavy battery with a lot of water in them. If I recall right, they are about twice the weight of the U220's or T-105's. They are TALL - like 16" tall, and have about 1" of water over the top of the plates, and are designed to stay in remote places, with generator back ups, not serviced more than once a year.

I think you will be fine. Even if uncovered for a little while, L-16's tend to come back to great service. Home Power Magazine did a story about recovering a set of 4 L-16's in a home that only had a back up generator, and the family left things on when they moved out. They where able to use one of these "Recovered" batteries in their main home power pack when they had a problem with one of their batteries in the main pack. Another pair of the old L-16's got installed in a older trailer not used for much, except visitors to the homestead where Home Power is written - miles off the grid.

So basically don't abuse it anymore, and you should be fine!

Good luck, have fun camping!

its too bad you didnt look at the batteries. My 4 U2200's took over 1/2G of water on one neglected fill, but the plates were never uncovered. I think thats almost twice what yours took

FWIW- Once a year I pull the batteries, now T-145's, and all the caps to make sure there are no debris clogs, and that all the levels are equal (telling me the float valves is functioning.
