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-hour capacity: Available amp-hours, at a fixed rate, over a given period of time (e.g. 20 hr rate, 5 hr rate., etc). Most true deep cycle batteries are at the 20 hour rate. A group 27 battery has about 100 amp hours (5 amps for 20 hours at 80 degrees F). The problem is no one uses exactly 5 amps. If you're pulling 10 amps, you may have a 70 amp hour battery; if you only draw 2, you may have a 140 amp hour battery.
