Understanding AGM Batteries
AGM batteries are one of the most widely used battery types in mobility equipment. Here's a closer look at what they are and why they're a popular choice.
Why choose AGM over a wet cell battery?
AGM batteries don't need topping up, are less prone to leaking, and tend to handle vibration and shock better than traditional wet cell batteries.
Looking after your AGM battery
Regular charging, even when your equipment isn't in frequent use, helps maximise the lifespan of an AGM battery.
Comfort, range and independence
Why Choose AGM Batteries
Sealed, spill-proof and maintenance-free — here's what makes AGM batteries a popular choice for mobility equipment.
Maintenance-free
Sealed construction means there's no need to top up fluid levels, unlike traditional wet cell batteries.
Spill-proof and safe
The electrolyte is held in a glass mat rather than as free liquid, making AGM batteries spill-proof, even if the casing is damaged.
Resistant to vibration and shock
A more rigid internal structure makes AGM batteries well suited to the bumps and vibration of everyday outdoor use.
Reliable, consistent performance
AGM batteries offer dependable power delivery and a good cycle life, helping keep your equipment running when you need it.
Buying guide
How to Choose the Right AGM Battery
A few things worth checking before choosing a replacement AGM battery.
1
Check the amp-hour (Ah) rating you need
Higher Ah ratings generally mean longer range between charges. Your existing battery's rating is a good starting point if you're replacing like-for-like.
2
Confirm the physical size fits your equipment
Battery compartments vary between models, so check the dimensions of your current battery or your equipment's manual before ordering.
3
Check whether you need one battery or a pair
Some scooters and powerchairs run on a single 12V battery, while others need two batteries wired together for a 24V system.
4
Get in touch to confirm compatibility
If you're at all unsure, contact our team with your equipment's make and model and we'll confirm the right AGM battery and arrange fitting if needed.

Common questions
AGM Batteries FAQs
Common questions about AGM batteries, including safety, lifespan and fitting.
What is an AGM battery, and how is it different from a standard battery?
An AGM (Absorbent Glass Mat) battery is a sealed lead-acid battery that holds its electrolyte in a glass mat rather than as free liquid. This makes it spill-proof and maintenance-free, unlike a traditional wet cell battery, which can need topping up and is more prone to leaking.
Are AGM batteries safe for air travel?
Yes. Because they're sealed and spill-proof, AGM batteries are widely accepted by airlines for transporting mobility scooters and powerchairs. It's always worth checking directly with your airline ahead of travel, as policies can vary.
How long do AGM batteries last?
Most AGM batteries last around 1-2 years with regular use, depending on how often the equipment is used and how well the battery is charged and maintained.
Can I fit the battery myself, or can you do it for me?
You're welcome to fit it yourself if you're comfortable doing so, but our team can also fit your new AGM battery for you, either in-store at our Lee-on-the-Solent showroom or as part of a home visit.
How do I know which AGM battery fits my equipment?
Get in touch with the make and model of your mobility scooter, powerchair or other equipment, and our team will confirm the correct AGM battery size and capacity for it.
