13 cze 2008 · exrench gives good advice. There is no reason to replace the batteries if they are still good, but are you sure they are "good"? The best way to find out is a specific gravity test, which you can easily do yourself with a simple $5 battery hygrometer, available at most places where auto parts and accessories are sold.
4 lip 2015 · Every indication I have received from Interstate is that the correct charge voltages for their GC2 series of batteries is: Bulk 7.23 volts in a dual 6 volt arrangement 14.46. Absorption 7.65 volts in a dual 6 volt arrangement 15.3. Float 6.7 volts in a dual 6 volt arrangement 13.4.
For charging, we recommend staying within 00F to120 0F (-18 to 49 C) to avoid charging frozen batteries at low temperature or going into thermal runaway at high temperature. For discharging, we recommend -200F to 120 0F (-29 to 49 C). Batteries discharged at temperatures below 320F (00C) should be re-charged immediately to avoid freezing.
Absorption charge time is determined by the battery but will usually be ~3 hours at 2.45 volts per cell. Float time is unlimited at 2.17 volts per cell. Specific gravity at full charge is 1.270 minimum.
31 sty 2010 · We have six Interstate U2200 batteries that are four years old. We rarely dry camp, we full time, and I'm fairly anal about maintaining the batteries. I'm wondering how long others have used their U2200 batteries before they had to be replaced.
