How Long Does A Calculator Battery Last. Should I stock up on a lot of the watch batteries it takes. How to Calculate How Long a Battery Will Last on an Inverter.

Average run cycle is 10 hours. The total load in this case is 250 Watts. As a general rule a 100Ah deep-cycle lead-acid battery discharged to 50 will run a 50 watt load for 12 hours a 200 watt load for 3 hours and a 400 watt load for 15 hours.
So your 150 AH inverter battery is expected to provide 576 hours in this particular case.
No idea what im going to do now -. Battery Life in hours Battery Capacity in Ah Load Current in A Example. Battery capacity is a measure typically in Amp-hr of the charge stored by a battery. Some calculators have a small solar panel which can usually generate enough electricity to power it - the battery is only there as a backup and so it can last for many more years without the battery going flat.
