watt = amp * volt
watt hour capacity = amp hour capacity * voltage
Calculate capacity in watt hour for the one which gives you mAh capacity with the following (dividing by 1000 to convert mA to A):
Wh capacity = (mAh capacity / 1000 ) * voltage

It occurs when Vbase rotio of both side of the Transformer is not the same as the Rated Voltge rotio.
-- If all 8 batteries have the same rated voltage as the inverter input, then they must be configured in parallel. -- If the batteries are not rated the same voltage as the inverter input, then some combination of series and parallel has to be designed. The specific configuration depends on the details of the batteries you have.
Nickel Cadmium batteries contain Cadmium, a toxic heavy metal, which is harmful to the environment. Nickel-Metal Hydride batteries offer a higher capacity(runtime)per same size(voltage output) than NiCd batteries and mcVolt Litium Ion laptop batteries have a higher capacity than NiMh(those sold by most manufacturers). NiMh batteries are also lighter and have little memory effect compared to their NiCd counterparts. mcVolt Li-ion laptop batteries are light, have a higher capacity and have no memory effect compared to NiMh and NiCd batteries.
Lithium batteries are button type.
Yuasa batteries are about the same quality as other batteries. You should expect to pay $100 or a little more for these batteries.
No
No, only rechargeable batteries can be recharged.
Series: Double the voltage of one of the batteries if they are the exact same size. Amps stay the same as one of the batteries. Parellel: Double the amps and voltage stays the same as one battery.
With the same load current the AA will last longer that the AAA. This is due to the physical size of the cells. A C cell will last longer that a AA and a D cell will last longer that a C cell. In dry cells as the cells get larger the amp/hours increase.
No
Batteries in series increase the voltage, which is important for powering certain types of flashlights effectively. By arranging batteries in series, the total voltage is increased while keeping the current the same, allowing the flashlight to produce brighter light. In contrast, arranging batteries in parallel would increase the current capacity but not the voltage, which may not be ideal for the flashlight's operation.
You have + and - on batteries, the polarities have to be in the same direction or the current won't flow.
