# Can I use a higher mAh battery in my flashlight?

Contents

In general, the higher the mAh, the longer the battery will last. … The mAh is the size of the gas tank and the battery’s voltage is how much gas is being used. The bigger the battery’s gas tank (mAh rating) the longer the flashlight will run.

## Can you replace a battery with higher mAh?

You can replace your battery with a slightly different mAh capacity, as long as it is the same voltage; we would recommend choosing your replacement batteries with the nearest possible mAh rating. It is not recommended to replace your batteries with a much higher mAh capacity.

## Can I use a 3000mah battery instead of 2000mah?

If the voltage is the same, then yes.

## Can I use 600mAh instead of 300mAh?

Yes, there should be no problems. If the voltage of the batteries are the same, then the 600mAh batteries will last twice as long as the 300mAh batteries. Just make sure the 600mAh batteries will physically fit into the device your using.

## Can I use 750mah instead of 550mAh?

Answer: You can always use rechargeable batteries with higher capacity numbers, such as 700mAh instead of 550mAh. The phone will work exactly the same with higher mAh batteries, except for longer talk time between recharge cycles.

## Can you mix batteries with different mAh?

Mixing batteries of different capacities will generally result in lower capacity battery drain first, while the higher one will not be discharged completely. This is not optimal usage and it’s not very good to recharge not-fully-discharged batteries. Therefore, mixing capacities is not recommended.

## Do mAh matter battery?

For a given battery form-factor (size), the higher mAh means higher battery capacity, so yes, it does matter. Does mAh affect battery power? mAh does not affect the battery power output, but it does represent how much energy is stored in the battery.

## How long does 500mA battery last?

Depends what you are powering from it, for example a normal LED is taking about 15mA (amperage is the measure for instant consume and ampere hour is for capacity – 1mA=0,001Amps), which means you can power it from 500mAh battery for 33 hours. As the “name” say, 500mAh is powering a 500mA consumer for one hour.

## Can I use 700mah instead of 300mah?

Yes. Mah is the capacity of the battery, so this just means a 700mah battery will hold a charge longer than a 300mah battery.

## Which is better NICD or NiMH?

Nickel-metal hydride (NIMH) batteries have a higher capacity than nickel-cadmium (NICAD) batteries, which means that they can generally power your device for longer. … Finally, NiMH batteries are much better for the environment than their NiCAD battery counterparts.

## Can I use 1000mAh instead of 800mAh?

So a battery rated at 1000mAh basically delivers 1000mAh (1 ampere) of current for one hour. A battery rated at 800mAh delivers . 80% of the charge of the 1000mAh battery and therefore, in an ideal world, would last 48 minutes instead of one hour powering the same device.

## What is difference between 300mAh and 400mah?

If the 400 mAh battery fits physically it will last about 4/3 longer than the 300mAh battery. The suffix “mAh” is the designation used to signify current storing capacity of a small battery. … I did a bit of research on this myself, and I believe the only difference is the 400 mAh will have a longer battery life.

## Can I use a higher mAh battery in my cordless phone?

Most AAA cordless phone batteries are 1.2V; never use non-rechargeable 1.5V batteries as this is dangerous. Replace your batteries with the same capacity; you’ll find this printed on the battery as a mAh rating such as 550mAh. It is a myth that the higher the capacity of the battery, the longer the phone will last.

## Is it better to have a higher mAh?

Batteries with larger mAh ratings generally last longer than those with smaller ratings, assuming that the batteries are subjected to the same patterns of usage, but it may not mean a better battery. The milliampere hour represents a unit of electrical charge commonly used to measure battery capacity.

## Can I replace a battery with a lower mAh?

Using a lower rated mAh battery pack will most likely just mean its battery life is shorter. Second, for rechargeable batteries, it tells you something about the safe rate at which the battery can be charged, often stated in C’s. So a 1400 mAh battery might ideally be charged at 1.4A maximum.
