Often the repair needed is not the most expensive part of the process at all. The actual repair may be just the replacement of a length of pipe or the removal of overgrown tree roots. It is the access that is the costly part of the equation.
How to charge a battery. An average car battery has a capacity of around 48 amp hours which means that, fully charged, it delivers 1 amp for 48 hours, 2 amps for 24 hours, 8 amps for 6 hours and so on.lways check the. level before connecting the battery to the charger. Top up if necessary (See Checking the batteries) and clean the battery posts. If there is a power point handy, the battery can be left in the car, so long as the charge rate is only 3 or 4 amps.
A basic charger usually charges at around 2 amps-and so needs 24 hours to deliver the 48 amps needed to fully charge a flat, 48 amp hour battery. But there is a wide range of chargers with different charge rates on the market-from 2 to 10 amps. The higher the charge output, the faster a flat battery is recharged.f there is a power point handy, the battery can be left in the car, so long as the charge rate is only 3 or 4 amps. However, if the car has an alternator, disconnect the battery. beforehand: otherwise some alternators-generally the older type-can be damaged. If separate. caps are fitted, remove them for ventilation.
