### **What is a LiFePO4 battery?**
Lithium iron phosphate (LiFePO4) is a type of lithium battery recognised as the safer chemistry for mobility scooters and powerchairs, compared to other lithium battery types.
### **Why choose lithium over lead-acid?**
Lighter weight, faster charging and a longer lifespan make lithium an appealing option, particularly for equipment that's used frequently or travels regularly.
### **Charging and safety best practice**
Always charge using the manufacturer-recommended charger, in a well-ventilated area, and avoid leaving any battery charging unattended overnight where possible.
**Comfort, range and independence**
## **Why Choose Lithium Batteries**
Lightweight, long-lasting and quick to charge, lithium batteries are a strong option for mobility equipment built to use them.
### **Significantly lighter weight**
Lithium batteries weigh a fraction of an equivalent lead-acid battery, making equipment easier to lift, transport and manoeuvre.
### **Longer lifespan**
Lithium batteries typically offer many more charge cycles than lead-acid batteries, often lasting several years with proper care.
### **Faster charging**
Lithium batteries generally charge more quickly than lead-acid alternatives, reducing the time your equipment is out of action.
### **LiFePO4 chemistry**
Built using lithium iron phosphate technology, recognised as the safer choice of lithium chemistry for mobility equipment.
**Buying guide**
## **How to Choose the Right Lithium Battery**
A few things worth checking before choosing a lithium battery for your equipment.
**1**
### **Check your equipment is suitable for lithium**
Some equipment is designed for lithium batteries from the factory, while others are built for lead-acid. Check with us before assuming a straight swap is possible.
**2**
### **Confirm the voltage and capacity you need**
Your replacement battery needs to match the voltage of your existing setup, with a capacity (Ah) that suits your typical usage.
**3**
### **Use the recommended charger**
Lithium batteries should be charged using a charger designed for that battery type. Always follow the manufacturer's guidance for your specific equipment.
**4**
### **Get in touch to confirm compatibility**
If you're at all unsure whether lithium is right for your equipment, contact our team with the make and model and we'll advise on the best option.

**Common questions**
## **Lithium Batteries FAQs**
Common questions about lithium batteries, including safety, lifespan and compatibility with your equipment.
Are lithium batteries safe for mobility scooters and powerchairs?
Lithium batteries designed for mobility equipment generally use LiFePO4 (lithium iron phosphate) chemistry, which is considered the safest type of lithium battery for this purpose, as it's far less prone to the thermal issues associated with other lithium battery types. As with any battery, always use the charger and settings recommended for your specific equipment.
What's the difference between lithium and lead-acid batteries?
Lithium (LiFePO4) batteries are significantly lighter than traditional lead-acid batteries, charge faster, and typically offer many more charge cycles over their lifetime. Lead-acid batteries, including AGM and gel types, are heavier but are well established and often more affordable.
Can I convert my lead-acid scooter to lithium?
Some equipment is designed from the factory to run on lithium, while other models are built specifically for lead-acid batteries. Converting a lead-acid scooter to lithium isn't always straightforward and should only be done with the right expertise. Get in touch and we can advise on what's suitable for your specific equipment.
How long do lithium batteries last?
Lithium batteries typically offer a longer lifespan than lead-acid batteries, often lasting several years and many hundreds of charge cycles with proper care, though this varies by usage and how well the battery is maintained.
How do I know which lithium 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 whether a lithium battery is suitable and which one fits.
