So commercial pipe lining jobs are quoted at typically double the residential rate as a rule of thumb. In addition, commercial facilities like factories and hospitals have to shut down while installation occurs, or bypass pumping has to be installed. This increases commercial pipe lining costs dramatically.
If you slow charge (about 2 amperhours) you will not cook the plates that are inside the battery. Depending on the deep cycle rate of the battery will depend on how long you will achive a full charge. With the battery that I have, it will take about 24 hours to charge on the 2 amp setting.f you slow charge (about 2 amperhours) you will not cook the plates that are inside the battery.

An equalizing charge for a 12 volt battery requires that it be charged with a voltage of at least 14.4 volts for a period of at least one hour once a month, or every 10 discharge cycles. An equalizing charge prevents battery stratification and reduces sulfation, the leading cause of battery failure. typical 125-AH RV or Marine battery will take approximately 80 hours to recharge at 13.6 volts. Increasing the charge voltage to 14.4-volts will reduce battery recharge time for a 125-AH battery to 3-4 hours.
