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.

You should not exceed the C/10 charge rate. If you have a 7 Ah battery in your field box the maximum constant current charge rate should not exceed 700 mA. It will take about 14 hours to charge from a fully discharged state (voltage less than 12 volts). A CVC (Constant Voltage Charger) is exactly what the name implies.
