## Description

**KRONOBAT Power Wheelchair batteries**: 12V AGM and GEL technology for power wheelchairs and mobility scooters, with capacities from 33 to 90 Ah. Compatible with the most common mobility brands: Permobil, Invacare, Sunrise Medical and Pride. The best-value mobility battery range in the Kronobat catalogue.
Built for users and family carers looking for an **affordable power wheelchair battery** once the original loses range, without giving up cycle life or the deep-cycle GEL technology that daily journeys require.

## KRONOBAT Wheelchair: deep-cycle AGM and GEL at the best price

The **KRONOBAT Wheelchair** range combines AGM batteries, for smaller models with lighter cycling demands, and GEL, the reference technology in electric mobility for its resistance to daily deep cycling (full discharge and recharge) without premature capacity loss. This is the most common reason a chair or scooter loses range over time, even when the motor and electronics are in perfect condition.

### KRONOBAT Wheelchair models and applications

- **KR33-12 AGM** (33 Ah) — small mobility scooter.
- **KR55-12 GEL** (55 Ah) — mid-size scooter and standard power wheelchair.
- **KR75-12 GEL** (75 Ah) — bariatric chair and large scooter.
- **KR90-12 GEL** (90 Ah) — Permobil F3/F5 and users needing extended range.

### How to choose your Kronobat wheelchair battery

Check the capacity (Ah) of your chair or scooter's original batteries (usually two are fitted in series) and the compartment dimensions: higher Ah extends your daily range. Use the [comparison tool](/gb/comparator) to see which Kronobat KR model fits your Permobil, Invacare, Sunrise Medical or Pride.

## Frequently asked questions about Kronobat wheelchair batteries

### **Are they compatible with my Permobil, Invacare or Pride?**

Yes, as long as the voltage, a similar or higher capacity (Ah) and the physical dimensions of the original batteries match, regardless of the chair or scooter's brand.

### **How long does a Kronobat wheelchair battery last?**

It depends on daily use and temperature, but the deep-cycle GEL technology is built to withstand repeated full discharge and recharge cycles without premature capacity loss.

### **What's the difference between AGM and GEL in these models?**

The AGM in the KR33-12 suits small scooters with lighter use; the GEL in the KR55, KR75 and KR90 better withstands the daily deep cycling typical of power wheelchairs in continuous use.

### **Can I fit a battery with more Ah for extra range?**

Yes, as long as the voltage matches and the battery physically fits the chair or scooter's compartment; more Ah translates directly into more range per charge.
