storage of 12v battery

what voltage should I store my battery @?

we run a minn kota endura c2 55# thrust electric trolling motor... we had it out on the sac river this weekend

the battery is a slr-100

Jimbo, I saw this the day it was posted but because I felt I didn't have any particular expertise, I didn't weigh in. Now the expeerts have had their chance, I'll add my 2 cents worth!

It is my understanding that batteries do best when a full charge is maintained or at least the down time is minimized. I use a MinnKota Endure 30 Lb thrust and as soon as I get home I hook my marine deep cycle battery to the charger. The charger will fully charge the battery and then switch over to maintenance mode, similar to a maintenance charger I have for my motorcycle during the winter. This way the battery is monitored and when the charge naturally drops a little bit, as programmed, the charger tops it back up. This is supposedly how the charged plates of the battery are maintained in peak condition.

ok, in that case, since it probably wont lose too much power in a week, I will just charge it with my rc car charger that does lead acid batteries every week or so....... up to full charge.....

charge specs on it say something like 10 amps @ 14.5 volts....... my charger will only do 5, so I just set it as a 14.5 volt battery @ 5 amps and it should be fine

Jimbo: One other tip that I learned the hard way, and anybody correct me if I am wrong, but definitely do not store a battery on a concrete floor. Apparently this not only causes it to lose charge rapidly, but then the storage with low charge greatly reduces battery life even after it is fully charged.

The old school batteries from way back had cases that would actually absorbe the acid and when set on concrete would discharge.
The new cases don't have that problem. If your battery is wore out it dont matter if its on the floor or on wood,it's just done for either way.
Even a new discharged battery can freeze.
