Repair and Excavation. If your yard, garden or driveway needs to be dismantled to repair your sewer main, then it stands to reason that a large cost of your repair will be replacing and rebuilding the parts of your home damaged in the process.
For example, if a deep cycle battery's capacity is rated at 100 ampere hours (AH) at the 20 hour (C/20) rate, it will produce approximately 83 AH at the eight hour (C/8) rate, 63 A in two hours (C/2), and 55 AH in one hour (C/1). This is due to the Peukert Effect.or example, a 40 amp hour battery with a 5% discharge would require approximately two amps hours to be replaced. Using a five-amp charger, it would take approximately 24 minutes (2 amp hours/5 amps x 60 minutes) to recharge the battery. A 10-amp charger would take approximately half the time or 12 minutes.
Test the Deep Cycle Battery's Voltage. After charging the battery, get a digital voltmeter to see how much charge it is holding. Next, let the battery sit for a few days and then check the charge again. If it is holding the same amount of volts, then it should be ready to use.
