If you ask any power wheelchair user what be a top priority for them might be when selecting a product they like, you’ll probably hear performance and reliability as a common response. After all, these two are just some of the key features that can drastically affect your power wheelchair experience.  

However, if you think about a carefully, both these two aspects rely rather heavily an essential component: the power wheelchair battery.

Your mobility wheelchair battery may be tucked away out of sight, and out of mind too, but it’s important to understand that it’s the core of your beloved electric wheelchair. And much like your own core center – the heart – electric wheelchair batteries must work hard and consistently to keep your wheelchair moving. If something goes wrong, the reliability, performance and even longevity of your power wheelchair could be adversely affected. 

At Scooters’N’Chairs, our mobility researchers and experts have gone to painstaking lengths to shortlist only the most reliable, highest-performing, and best-loved electric wheelchair batteries currently available across the nation. Our range of top US brand replacement batteries for electric wheelchair offer powerful and reliable performance at some of the best prices you might find online today. 

Each one of the replacement electric wheelchair batteries on offer are fully rechargeable and have the ability to work with a broad range of power wheelchairs. We have both lead acid batteries and gel batteries available with us – both being maintenance-free and spill -roof – while each product is also covered under a minimum one year manufacturer’s warranty. 

Your powered wheelchair is a fine piece of engineering if you think about, and in order to enjoy uninterrupted mobility, you will not only need to take really great care of it, but also ensure that you always have a pair of fully charged spare batteries, in case you ever need to travel longer than normal distances. Furthermore, replacing your power wheelchair’s current battery with a more robust and powerful one can help you get better use and pleasure out of your mobility companion.

When it becomes necessary to buy replacement Electric Wheelchair Batteries

Perhaps you’re a mobility wheelchair veteran, or maybe you have just bought yourself one, fresh off our lineup. No matter how much experience you have with them, it is inevitable that you’re going to expect a certain level of reliability and performance from your mobility companion. Because, frankly speaking, your electric wheelchair’s purpose is to serve you to the best of its abilities, and do what you want it to do, in a way that’s both practical and efficient.

Naturally, with the passage of time, you might start asking yourself questions like: “What’s the best way to increase my new wheelchair’s travel range?” or “what can I do to ensure that I’m getting the most bang for the buck out of my investment?” – Or even something like: “I love traveling long distances, so is there any possible way to make the battery last longer?”

Well – unsurprisingly – all these questions share one thing in common: they all hinge heavily on your power wheelchair’s battery and what kind of travel range it can help you cover on a full charge. 

Now, with that said, if you don’t use your electric wheelchair on a very regular basis, even a small pair of extra batteries might serve you well, as you’ll always have a spare ready and fully charged up – rather than waiting a few hours or leaving it on overnight charge. 

On the other hand, if you’re someone who gets heavy use out of your mobility companion on a day-to-day basis, then a pair of robust, good quality electric wheelchair batteries can be one of the best investments you can ever make. Especially when you need to make emergency doctor’s appointments and travel long distances or just accompany the family on that impromptu vacation. 

You’ll never have to worry about your power wheelchair dying in the middle of all the fun and excitement or trying to work out when you’ll have to charge up your mobility buddy next. 

At Scooters’N’Chairs, our broad ranging selection of batteries for electric wheelchairs offer highly varied options according to your budget and travel distance requirements. 

At just $99, the UPG 12V/12Ah sealed lead acid batteries by Universal Battery are budget electric wheelchair batteries featuring an SLA (sealed lead acid) design – capable of providing high battery life for demanding everyday applications. The spill-free construction means that none of the battery acid can leak out which also makes it maintenance-free. Being a “non-hazardous” item, it is approved for airplane, train and boat/ship travel. 

Priced at just $127 is another of our entry-level spare power wheelchair battery – the MK Battery (pair), 12V/12Ah sealed lead acid/premium AGM batteries that have been a top choice for power wheelchair manufacturers for years. MK AGM is a hallmark of quality and performance and has become a standard when it comes to driving mobility products forward. They can be shipped easily all over the nation as they are UPS, IATA and FAA approved. 

Throw in $180 and you can get the MK twin-battery deep-cycle pack, a larger battery to keep up with your daily travel demands. 

If you want to invest in one of the best electric wheelchair batteries currently available, then the $425 Sealed Gel 12V/40Ah batteries by MK Battery is an easy choice – with a laboratory-tested 500 cycles. 

Many power wheelchair users like to call it a “low liability” battery as there’s no water-maintenance required as such – the suspended electrolyte/gelled batteries are completely sealed and do not require any liquid to function normally. At $716, you can buy MK Battery’s more powerful sealed gel battery pack variant, rated at 12V/88Ah. 

With battery technology changing dramatically in the last few years, both MK and Universal Battery offer some of the most advanced and sophisticated power wheelchair battery designs, delivering vastly more power and consistent performance levels over other brands. They’ll last you much longer than other mobility wheelchair battery types, while being safe and approved for airline as well as public transport travel.

Understanding Components of a Power Wheelchair Battery

Now that you’re familiar with our range, it’s important to understand how the three basic components of electric wheelchair batteries come into play. Let’s break it down:


It’s probably fair to say that most users are interested in this right off the bat, and it only makes sense – capacity tells you how long your mobility wheelchair battery will last, a unit which is almost always shown in “Ah” or ampere-hours

Let’s say your electric wheelchair is capable of running at 10Ah while the battery has a capacity of anywhere between 30Ah and 90Ah – your mobility companion can easily run between 3-9 hours, if you run it non-stop, that is. However, it’s quite likely that you may not need to use your power wheelchair non-stop at a stretch, unless you’re planning to take a long-distance trip – meaning that your battery will last well over 9 hours. 

Current Rating 

This refers to the rate of electron or current flow and is relayed in Amperes. Batteries with higher Amperes means you’ll get better performance if you need to use your mobility wheelchair over slopes or generally uneven/rough terrains. 

Cell Type

Broadly speaking, there are two main kinds of wheelchair battery cells: gel and wet.

Owing to the fact that the latter require a lot of maintenance and pose a threat to the environment, we provide only gel-cell batteries as they are environment-friendly, completely sealed and are maintenance-free since they require no liquid. They are also safer as the risk of acid corrosion is absent due to being liquid-free and spill-free.

A quick word of caution: when you buy your replacement or spare mobility wheelchair battery, ensure that you’re using the correct charger, if it’s a battery other than the one that came with your product. By using an improper battery charger and/or cables, you may damage your battery permanently. 

If you’re not sure what kind of charger to use with your newly purchased power scooter battery, please get in touch with our support team, who would be more than happy to provide guidance. 

Since electric wheelchair batteries are “deep cycle” by nature, they need to be fully discharged before you can charge them again. Most of the batteries in our range can be recharged between 300-500 times or have as many cycles – which means you can keep using them this many times, until their power holding capacity starts to diminish.   

Keeping Your Mobility Buddy ‘Healthy’ – How to Take Care of Electric Wheelchair Batteries  

To ensure that your batteries for electric wheelchair last and perform optimally throughout their intended shelf life, you should understand how to correctly charge and store them, among other things. 

Let’s take the following into account:

Average ‘shelf life’ of a power wheelchair battery

Depending on the kind of battery you have purchased, electric wheelchair batteries may last anywhere from 6-10 months or up to 2-3 years or more. However, this largely depends on several factors including:

How much use you’re getting out of your electric wheelchair each day and the kind of surfaces you use it on – both influence how the battery gets used up. So for instance, if you have a very active routine and love spending time outdoors, exploring a few ‘beaten paths’ will certainly cause more wear on your electric wheelchair battery. Hard, solid and relatively flat surfaces, on the other hand, means that your battery will comfortably perform not only according to its average life expectancy, but even exceed it, in some cases. 

Even though user weight is somewhat of a fixed factor, it can certainly affect battery life. So as you might imagine, users who weigh less see their power wheelchair battery lasting longer. Plus, carrying heavy items with you on a day-to-day basis will mean higher battery strain. 

Finally, the frequency at which you charge your battery can significantly affect its maximum shelf life.

Properly charging your mobility wheelchair battery

If you lead an active lifestyle and use your power wheelchair just about every day, then you may need to charge the battery every day as well, which can actually be a good thing, depending on certain usage factors

To optimize your battery’s total lifespan, we’d advise that you charge it daily. However, it’s also important to remember that you don’t want to do this every day if you still have a good 30-50% charge left. It’s better to let it drop to at least 10-20% before attempting a recharge. In addition, let your battery charge up to at least 50% or more before using it. 

Here are more power wheelchair battery charging “best practices”:

  • Try to resist the temptation to use your power wheelchair until the battery almost reaches 0% charge. However, at the same time don’t keep topping it off just because it has come down to, say, 25% or 30%. 
  • Charging in ‘short bursts’ is alright if you want to bring the charge up to about 50% or more for long distance traveling – just don’t make this frequent ‘topping off’ practice a daily ritual as it may cut down your battery’s intended lifespan. 
  • If you’re not going to be using your wheelchair too often, then leave it on overnight charge at least once a week to keep the battery topped off.
  • While keeping all of the above in mind, it is generally better to let your battery come down to perhaps 10-20% charge and then overnight charge it. Don’t worry – the automatic cut-off switch will disable the power once you have achieved a full charge.

Taking care of your electric wheelchair batteries

It’s always a good idea to avoid temperature extremes – and despite the automatic cut-off capability, we would not recommend leaving the charger plugged in for too long or when you’re not using your wheelchair.

Several different types of batteries are used by mobility vehicles. Each performs differently, especially in terms of how long it lasts per charge and the amount of time it takes to fully charge.

Within each battery type, the size of your battery will be directly proportional to the range and weight limit of your scooter. Another factor to look out for is amps. The higher the amps mentioned, the more the vehicle’s power.

Three extremely popular technologies are lead acid, lithium-ion and gel-cell batteries.

Gel-cell batteries come sealed so they require almost no maintenance. Although they cost more than other kinds, gel-cell batteries are extremely safe and will never leak. They are FAA certified batteries so you can take them on airplanes. They also do not need to be fully discharged before recharging which is very handy.

Lead Acid (Wet Cell)
Lead acid or wet-cell batteries are cheaper than other kinds but they’ll need you to maintain them. Every so often their water levels must be checked and topped up if necessary. They last a little longer that gel-cell batteries - up to an extra six month battery life - but they do carry the risk of acid spills.

Lithium-ion batteries are the next big thing in scooter and wheelchair batteries. Amazingly, they offer a largely extended range whilst maintaining, and often lowing by four times, the battery weight and by extension the entire vehicle weight. These often cost a little more, but most customers think it totally worth it.
You’ll find more modern models, especially those designed for easy transport, using these newer technology lithium-ion batteries. Some airlines permit lithium-ion batteries, making your journey super easy – always check before you travel.
