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.
The cheapest way to charge a nickel metal hydride battery is to charge at C/10 or below (10% of the rated capacity per hour). So a 100 mAH battery would be charged at 10 mA for 15 hours. This method does not require an end-of-charge sensor and ensures a full charge.
