Mobility Scooter Batteries

You do not need to know your battery size, your Ah rating or your charger type. Bring the scooter or wheelchair to us and we will identify what is fitted, tell you what it needs, and change it there and then.

If you would rather work it out first, the number you need is the capacity in Ah printed on the battery already fitted. Match that and you cannot go far wrong.

One thing worth knowing that most people are never told: some scooters and wheelchairs have physical room for a larger battery than the manufacturer fitted. Where that is the case, going up a size gives you a greater range on a charge and longer between recharges, for very little extra. We will tell you if yours is one of them.

While you wait

Mobility Scooter Batteries Fitted While You Wait

Bring the scooter to us and we will test the existing batteries, tell you honestly whether they are actually finished, and fit a matched pair if they are. Most jobs are done inside the hour, and you are welcome to wait in the office rather than arrange a second trip.

We fit AGM and gel batteries as a matched pair, never one new against one tired, because mixing them simply drags the new battery down to the condition of the old one. If your charger is the underlying problem we will tell you that too, rather than selling you batteries that will fail the same way.

Sizes we stock

Mobility battery sizes explained

Mobility batteries are classified by their Ah value, and that value is really what determines the physical size of the battery. These are the main ones, and we hold all of them.

7AhSmallest, typically lightweight folding models.
12AhCommon on compact boot scooters.
18–22AhMid-size pavement scooters.
24–26AhLarger pavement and road-legal models.
31–34AhBigger road scooters and powerchairs.
40–44AhLong-range road-legal scooters.
50AhHeavy-duty use and longer journeys.
70AhThe largest we supply.

Most mobility scooters and wheelchairs run two 12 volt batteries wired in series to make a 24 volt system, charged with an automatic 24V charger. That is why batteries are almost always replaced as a pair rather than singly — mixing a new battery with a tired one drags the new one down to the old one within months.

Which type

Lead-acid, gel or AGM?

There are three types you will come across. All of ours are sealed — either sealed lead-acid or gel — so there is nothing to top up and nothing to spill.

Sealed lead-acid

The most affordable option and perfectly good for everyday use. Sealed, so no topping up. This is what most people replace like for like.

Gel

Costs more than lead-acid. Cannot be spilt and needs no maintenance at all. Gel batteries are accepted for air travel, which matters if the scooter goes on holiday with you.

AGM

The newest technology and the most expensive. No spilling, no maintenance, and noticeably more resistant to shock and vibration. Also accepted for air travel.

If you fly with your scooter, tell us before you buy. Airlines have rules about battery type and sealed gel or AGM is normally the straightforward answer. It is a lot easier to sort now than at a check-in desk.

Getting the most out of them

How long should a battery last?

All mobility batteries are rechargeable, and realistically they need replacing every 12 to 18 months. You charge them from an ordinary electric socket, and most scooters can be charged without taking the batteries out at all.

Two habits make a real difference to how long they last:

Do not run them flat

Repeatedly draining a battery all the way down shortens its life more than anything else. Top up before you have to, not after.

Charge them promptly

Do not leave a dead battery sitting for more than a day without charging it. That is when lasting damage happens.

Watch the gauge

The meter on the control panel — a coloured dial, a set of lights or a digital display — tells you where you are. Check it is full before you set off.

An honest word on range: treat the manufacturer's stated range with caution. Hills, cold weather, your weight, heavy shopping and the age of the batteries all cut it down. To avoid being stranded, plan on getting about half the quoted range between charges. We would rather you knew that than found out the hard way.

Chargers

Charger types, briefly

There are a number of chargers depending on battery size and each manufacturer's own plug system. The most common is a three-pin plug that inserts directly into the scooter's battery system. Where that is not the case, a standard 24V automatic charger with crocodile clips will normally do the job.

If your charger has stopped working, or you are not sure it is charging properly, bring it in with the scooter. A battery that seems to be failing is sometimes a charger that has quietly given up, and replacing the wrong one is an expensive mistake.

Spread the cost with Payment Assist

A pair of larger mobility batteries is not a small purchase, and it is rarely a planned one. We are a Payment Assist garage, so you can split it into monthly instalments and still ride away the same day. Just ask when you come in.

Not sure what you need?

Send us a photo of the battery

The quickest route to the right battery is a photo of the label on the one currently fitted, or the make and model of the scooter. Message it over and we will tell you the size, the price and whether we have it on the shelf.

Mobility batteries: your questions

The things people actually ask at the counter.

How do I know what battery my scooter needs?

The number that matters is the capacity in Ah printed on the battery already fitted. Match that and you are right. If you cannot find it or would rather not crawl about looking, bring the scooter in or send us a photo of the label and we will identify it for you.

Is fitting included?

Yes. All our mobility batteries come with fitting, and we can normally do it while you wait so you get moving again the same visit.

How long do mobility scooter batteries last?

Realistically 12 to 18 months. They will last longer if you avoid running them all the way down and if you charge them promptly rather than leaving them flat for days at a time.

Should I replace both batteries at once?

Almost always yes. Most scooters and wheelchairs run two 12 volt batteries wired in series to make 24 volts. Pairing a new battery with a tired one drags the new one down to the old one within months, so replacing as a pair is the cheaper option over the life of them.

Can I fit a bigger battery than the one on it now?

Sometimes. Some scooters and wheelchairs have physical room for a larger battery than the manufacturer fitted, and where that is true a bigger one gives you more range and longer between charges. We will tell you if yours has the space.

What brands do you stock?

Six brands so we can cover everything from a tight budget to the best available, including Yuasa, Numax, Exide and Bosch.

Lead-acid, gel or AGM: which should I get?

Sealed lead-acid is the most affordable and is fine for everyday use. Gel costs more, cannot spill and needs no maintenance. AGM is the newest and most expensive, with the best resistance to shock and vibration. Gel and AGM are both normally accepted for air travel.

I want to take my scooter on a plane. Does that change things?

It can, so tell us before you buy. Airlines have rules on battery type and a sealed gel or AGM battery is usually the straightforward answer. Much easier to sort now than at a check-in desk.

Do you collect and deliver?

Yes, across the whole Merseyside area. If you cannot get the scooter to us, ring and we will arrange collection and return.

Why does my scooter not go as far as the manufacturer says?

Because those figures are measured in ideal conditions. Hills, cold weather, your weight, heavy shopping and the age of the batteries all reduce it. Plan on roughly half the quoted range between charges and you will not get caught out.

My battery seems fine but the scooter is not charging. What now?

Bring the charger in with the scooter. A battery that appears to be failing is sometimes a charger that has quietly stopped working, and replacing the wrong one is an expensive mistake. We will test both.

Can I spread the cost?

Yes. We are a Payment Assist garage, so a pair of larger batteries can be split into monthly instalments. Ask when you come in and we will run through it.
