Standard dry-cell round batteries such as AAA, AA, C or D are all 1.5 volts. Multiply 1.5 by the number of batteries. So, four batteries would equal 6 volts; six batteries would equal 9 volts and so on. Find the current or amp (mAh) rating either in the specification sheet in the device's manual or on a sticker on the device itself.
Multiply 1.5 by the number of batteries. So, four batteries would equal 6 volts; six batteries would equal 9 volts and so on. Find the current or amp (mAh) rating either in the specification sheet in the device's manual or on a sticker on the device itself. This value is the current (mAh) for which the adapter should be rated.
Nothing, except you likely get less capacity with four 9V batteries in parallel than with six 1.5V batteries in series. And because connecting batteries in parallel is generally not a good idea. Comparing 9V and 1.5V batteries of the same chemistry from same manufacturer, both drained to 0.8V per cell:
At 250 mA load current, 1.5V battery has 2000 mAh, and with five 9V batteries each delivering 50mA, they would add up to slightly more than 2000 mAh in capacity. So how many 9V batteries you would need to match running time depends on the current consumed by the device, because 9V batteries have more losses than AA batteries.
Six 1.5V AA batteries would give capacity of 3000mAh at 25mA, and even 2000mAh at 250mA load. At 100 mA load current, 1.5V battery has more than 2500mAh, four 9V batteries at 25mA each is less than 2400mAh.
9v Cell replacement option 2. You can cut the 9v connection plug and either join wire to extend it out of the cavity. Add a male deans plug to the wires. Sometimes extending or running the wire out of the battery compartment is necessary as the 18650 batteries may not fit in the compartment.

Learn how to arrange batteries to increase voltage or gain
Portable equipment needing higher voltages use battery packs with two or more cells connected in series. Figure 2 shows a battery pack with four 3.6V Li-ion cells in series, also known as 4S, to produce 14.4V nominal. In comparison, a six-cell lead acid string with 2V/cell will generate 12V, and four alkaline with 1.5V/cell will give 6V.

NiMH (Nickel-Metal-Hydride) Battery: A Complete Guide
A single NiMH battery has a nominal voltage of 1.2V, while a single lithium-ion battery is typically 3.6V. This means you can''t directly replace a NiMH battery with a lithium-ion battery of the same size, as the voltages are incompatible. You would need to use multiple lithium-ion cells in series to match the voltage of the NiMH battery pack.
