How many hours can a 100ah battery last?
1000 hours
A very small user of power is a 1.2 watt LED light running on a 12 volt power source will use 1.2W / 12V = 0.1 amps. Therefore a 100ah (amp hour) battery will last for 1000 hours.
A deep cycle battery is a lead battery designed to provide sustained power over a long period and run reliably until it is 80% discharged or more, at which point it needs to be recharged
One is what the letters UPS (uninterrupted power supply) stand for. It maintains continuity of supply to load even when power fails, taking help of battery for energy and power. So without battery and input connected, UPS will continue giving output, but with these constraints, so long as input voltage is available.
If this problem comes up, then either the input is not connected or the fuse must have melted. Check the power cable and change the fuse respectively for the above given reasons for a power inverter working just in the inverter mode. However, if the cause is input protector being effective, then you must reset it.
If your battery shows a good voltage when it’s fully charged, but quickly drops voltage to 11V or less when using power, this usually means the battery has a faulty cell and needs replacement. When a deep cycle battery is fully discharged (dead flat), it should reveal a reading of approximately 10.5V.
