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.

Amp Hours, or Ah, is the capacity of the battery. How much current a battery can delivery starting a car is called cold cranking amps. A deep cycle marine battery will typically be more than 40Ah. A 40Ah car battery at 50% charge will more than likely start your car in fair weather.Cold weather is another story. So, to get a completely dead car battery to 50% - 20Ah-would be maybe two days of full sunlight-with only a 50% charge, or about 12.2 Volts.t will take forever and a day to charge a deeply discharged deep cycle battery.......... consider that a small 110v battery charger is putting out 3-5 amps (or 3 x 110 =330 Watts) and the alternator on a car is putting out 20 to 50 amps at 14 volts (280 to 730 Watts).
