yes for the Rotaract district 1070 camping weekend.... gotta power that fridge with something for 24 hours... plus the music, are you missing not comming now ?
How long since it was last charged/floated? If it has been sitting idle for several months, chances are that when combined with ~50ft of rope, it will make a great accessory for your boat. Idle flooded-cell batteries loose about 10% of their charge per month, especially in the summer. Sealed-Lead-Acid (SLA) batteries loose about 3-5% per month.
When idle, flooded-cell lead-acid batteries should be recharged (to make up for self-discharge) at least every two weeks, more in hot climates. SLA batteries should be recharged at least once per month.
I keep all my little-used batteries on continuous float-charge: 12.9 to 13.2V for flooded-cell, and 13.4 to 13.6V for SLA.
For charging, 14.2-14.5V for flooded-cell, and 14.7-14.8V for SLA. Switch the charger to the float voltage when the charging current drops to < 0.25A (for a 50 to 125AH battery).
13 - 13.2V is about right on for a continuous charge on a "12V" wet cell lead acid. For fast charge, 14V is OK as long as it is not left on it indefinitely.
BTW: the battery makers publish recommended voltages for rapid charge and float charge for their batteries.
