What type of batteries do electric water guns use?

Oct 21, 2025

Hey there! As a supplier of electric water guns, I often get asked about the types of batteries these nifty gadgets use. So, I thought I'd sit down and write this blog to share all the ins and outs of it with you.

First off, let's talk about why batteries are such a big deal for electric water guns. Unlike the old - school manual water guns that rely on good ol' muscle power, electric water guns use batteries to power their motors. These motors are what pump the water out at high pressures, giving you that satisfying and powerful spray.

The most commonly used batteries in electric water guns are rechargeable ones. There are a few reasons for this. For starters, they're more cost - effective in the long run. You don't have to keep shelling out money for disposable batteries every time the power runs out. Also, they're better for the environment. Less waste means a happier planet, right?

One of the popular types is the Lithium - Ion (Li - Ion) battery. These batteries are known for their high energy density. What does that mean? Well, it means they can store a lot of energy in a relatively small and lightweight package. This is great for electric water guns because you want them to be portable and easy to handle. With a Li - Ion battery, your electric water gun can have a decent amount of power without being too heavy to carry around.

Another advantage of Li - Ion batteries is their long lifespan. They can handle a large number of charge - discharge cycles before their performance starts to degrade. So, you can use your electric water gun for a long time without having to worry about replacing the battery too often.

However, Li - Ion batteries do have a few drawbacks. They can be a bit expensive compared to other types of batteries. Also, they need a special charger to ensure they're charged safely. If you overcharge or discharge them too much, it can damage the battery and even pose a safety risk.

Another type of battery you might find in electric water guns is the Nickel - Metal Hydride (NiMH) battery. NiMH batteries are a good alternative to Li - Ion ones. They're generally cheaper, which makes them an attractive option for budget - friendly electric water guns.

NiMH batteries also have a relatively high energy density, although not as high as Li - Ion batteries. They can hold a decent charge, which means your electric water gun will be able to shoot water for a reasonable amount of time before needing a recharge.

One of the benefits of NiMH batteries is that they're less prone to the "memory effect" compared to older Nickel - Cadmium (NiCd) batteries. The memory effect is when a battery "remembers" the level to which it was repeatedly discharged and loses its ability to hold a full charge. With NiMH batteries, you don't have to worry about this as much.

But, NiMH batteries do have a higher self - discharge rate. This means that they'll lose their charge even when they're not being used. So, if you leave your electric water gun sitting around for a few weeks, you might find that the battery is almost dead when you come back to use it.

Now, let's talk about the different applications of electric water guns and how the choice of battery can affect them.

If you're using an electric water gun for small - scale cleaning tasks around the house, like washing your car or cleaning your patio, a battery with a moderate power output will do the job. For example, a NiMH battery might be a great choice. It can provide enough power to get the job done, and it won't break the bank. You can check out our Mini Portable Washer, which is perfect for these kinds of tasks. It's powered by a reliable battery that gives you a good amount of cleaning power.

On the other hand, if you're looking for a high - performance electric water gun for more heavy - duty cleaning, like cleaning large industrial equipment or a big commercial space, you'll need a battery with a higher energy density, like a Li - Ion battery. Our High Pressure Wash Gun is a great example. It's designed to deliver a powerful and consistent spray, and a Li - Ion battery is just what it needs to keep up with the demand.

For those who want the ultimate in convenience and portability, our High Pressure Cordless Water Gun is the way to go. With a high - quality Li - Ion battery, it can be used anywhere without the hassle of cords. You can take it to the garden, the car wash, or even on a camping trip.

When it comes to choosing the right battery for your electric water gun, there are a few things you should consider. First, think about how you're going to use the water gun. If you need it for occasional light use, a less expensive battery might be sufficient. But if you're going to use it frequently and for tough jobs, investing in a high - quality Li - Ion battery is a good idea.

You should also consider the battery's capacity. The capacity is measured in ampere - hours (Ah). A higher capacity battery will be able to power your water gun for a longer time. However, keep in mind that a higher capacity battery might also be heavier and more expensive.

Another factor is the charging time. Some batteries can be charged quickly, while others take longer. If you're in a hurry and need to use your water gun again soon, a battery with a short charging time is a must.

As a supplier of electric water guns, I know how important it is to choose the right battery. That's why we offer a range of electric water guns with different battery options to suit your needs. Whether you're a homeowner looking for a simple cleaning tool or a professional in need of a high - performance water gun, we've got you covered.
