Battery Replacements

The right battery, the first time.

Replacement batteries for scooters, power chairs, and other powered mobility equipment. SLA, Gel, and Lithium options matched to your equipment, with voltage and chemistry verified before you order.

SLA, Gel, & Lithium
We match the chemistry to your equipment. Sealed lead-acid, gel, and lithium options available.
Voltage verified
We confirm voltage and connector type before you order. Wrong voltage damages the controller.
Real advice, no charge
Not sure what you need? Send a photo of the battery compartment. We’ll help you figure it out.
Signs your battery is failing

If you’re seeing two or more of these, it’s probably the battery.

Batteries weaken gradually. The equipment usually still powers on, but the warning signs are unmistakable once you know what to look for.

Shorter run time
You used to get a full day. Now you’re barely making it to lunch.
Slow to charge
Charging takes much longer than it used to, or never quite reaches full.
Won’t hold a charge overnight
Fully charged at bedtime, half-empty by morning. The battery is leaking power.
Gauge drops rapidly
The charge meter falls from full to half within minutes of use.
Slow performance
Acceleration feels sluggish. Top speed isn’t what it used to be.
Struggles on inclines
Slight hills used to be no problem. Now the equipment slows or stalls.
Cuts out unexpectedly
Equipment shuts off mid-use, then comes back on a few minutes later.

Most mobility batteries last 1.5 to 3 years with regular use. After that, weakness is normal wear, not a defect.
Battery chemistries

Three chemistries we work with.

Yours is determined by your equipment, not by preference. Use this to identify what you have. We’ll confirm the right replacement before you order.

Sealed Lead-Acid
SLA
The default in most mobility scooters and power chairs. Affordable, heavy, reliable. Two sub-types: AGM (most common) and Gel (longer-lasting under heavy use).
A type of SLA
Gel
Used in higher-capacity scooters and equipment that needs longer life under heavier use. Same charger as AGM. A step up in durability, often supplied with larger Ah ratings.
LiFePO4
Lithium
Lightweight, longer lifespan, faster charging. Found in newer travel scooters and premium models. Cannot use an SLA charger. Equipment has to be designed for it.
Not sure what’s in your equipment? Open the battery compartment and photograph the existing battery label. We’ll identify it and confirm a compatible replacement before any order is placed.
How it works

Two ways to order the right battery.

Whichever path makes sense, we verify voltage, connector type, and chemistry before any order goes through.

You know the details

Send us the make, model, and battery type.

If you have the equipment make, model, and current battery specs (voltage, Ah, chemistry), use the parts form. We confirm availability, pricing, and lead time. You approve before we order.

Order a Battery
You’re not sure

Send a photo of the battery compartment.

Open the compartment and snap a photo of the current battery (or the label on it) plus a photo of the equipment. We’ll identify the right replacement, the chemistry, and any charger compatibility issues before you order.

Safety first
Wrong voltage costs you twice.
A 36V battery in a 24V system can fry the controller and motor in seconds. A mismatched charger can damage a lithium battery to the point of fire. Call us before you order. We confirm voltage, chemistry, and charger compatibility, no charge.

Charger problem instead?

Sometimes the battery is fine. It’s the charger that’s failing.

If charging is inconsistent, slow, or the battery never reaches full, the charger or charging port may be the real issue.
