Where batteries are joined
in parallel, add the capacities
together, the voltage will
remain the same as each
batteries voltage.
2 x 12 Volt 150 Ah batteries connected in parallel would have a
capacity of 12 Volts – 300 Ah.
Only use identical batteries when joining batteries together.
How long will my battery last
To work out how long your battery will last follow this basic guide.
This guide presumes commencing with a fully charged battery.
Take the total rating of the appliance being run
1 light globe 25watts
1 20 inch TV 67watts
1 VCR 30watts
Total load =122watts
Divide this figure (122) by 10 to know the approximate DC current draw
=12.2Amps
To convert this to Ampere hours, multiply by the number of hours used -
Say 1 hour =12.2Ah
So if we have a 150Ah battery, then with the above example we should have
150 minus 12.2 = 137.8 Ah remaining in the battery.
As a general guide never discharge a battery below 50%. The deeper
a battery is discharged on a regular basis, the less life you can
expect from the battery. The Ah rating of a battery will also be
reduced if the discharge rate is significantly greater than the rated
discharge current. See your battery specifications for full details.
