Hello friend in d.c power=v*iso, the total power of battery will =12*100=1200 watt or ah .The power will taken by yous load is 300 watt so,the battery can give power upto 1200/300=4 hour .
To determine how long a 100Ah battery will last with a 20W light, you first convert the wattage to amps. Using the formula: Amps = Watts / Volts, and assuming a 12V battery, the light draws about 1.67A (20W / 12V). Therefore, a 100Ah battery would last approximately 60 hours (100Ah / 1.67A) under ideal conditions, without accounting for factors such as battery efficiency and depth of discharge.
Commonly this figure is used for battery used for cars or UPS. 100Ah means, you can draw 100 Ampere current for one hour. Like a battery 0f 12Volt,7Ah can be used for a circuit which draw current of 1 Amp. can be used for approximately 7 hours.

based on the load,your battery back up may determined.for 600va inverter u can provide a maximum load of 460w(app.)for fan its 80w and tubelight it's 40w.if your using 100ah battery,your backup for running the 2 fans and 2 light have load upto 240w is 5hours(app.).duration may differs based on the efficiency of the battery
The amperage of a 12V battery depends on its capacity, which is measured in ampere-hours (Ah). To calculate the amperage, you would divide the capacity (Ah) by the voltage (V). For example, a 12V battery with a capacity of 100Ah would have an amperage of 8.33A (100Ah / 12V).
A 55 Ampere Hour battery is not recommended for your car. The recommended battery is a group 49, with 100AH and proper venting. Other sizes will not fit and incomplete venting is dangerous.
there is no problem , it's the same way to charge the battery in 12V . whatever the 50ah ,100ah ,or 60ah . the only difference is the charge time Allan Skype :Minjia002
To determine how long a 1000VA inverter can provide backup power, first calculate the total wattage of the devices: if each fan is around 50W, lights are 10W each, and the TV is 100W, then the total load is approximately 600W. A 1000VA inverter can handle this load, but the runtime depends on the battery capacity. For example, a 12V battery with 100Ah capacity can provide about 1200Wh, which would last roughly 2 hours at a 600W load, factoring in inverter efficiency and battery discharge limits.
It depends on the voltage and current ratings of the battery. Most rechargeable batteries have these values printed on them. Lets say it is 1.25 V and it is 2000 mAh. This means it can provide, ideally, 1.25 and 2 amp for 1 hour (1.25 V and 1 amp for 2 hours). I think you got the idea. So it is 1.25*2=5 Watts.
When referring to vehicle batteries 663, 664 is a UK code to describe principly the dimensions and terminal layout, in the case of 663 conventional and 664 opposite. Typically 100AH and 700 cranking amps
The BMW E34 typically uses a 12V battery, with common sizes being Group 48 or Group 49, depending on the specific model and engine configuration. The capacity generally ranges from 70Ah to 100Ah. It's important to check the owner's manual or the specifications on the existing battery to ensure the correct fit and performance.
i put a 100Ah 830cca Bosch HSB019 in my 320d touring 2002, replacing the HSB017 90Ah/720cca. same width but taller and longer. the plastic block at the bottom cradle needs to be removed for it to fit lengthwise and the tail light wire loom was rubbing on the neg terminal wire so I put a 1/16" thick plastic shield there. no problem with new height.
