Kronobat ES3-12 · Wheelchair battery 12V 3Ah AGM

Mobility battery Kronobat ES3-12 AGM Deep Cycle 3Ah 12V

Designed for power wheelchairs, mobility scooters and light electric vehicles, the Kronobat ES3-12 from the AGM Deep Cycle range offers 3 Ah of deep-cycle capacity with AGM technology. Its 134 × 67 × 65 mm make it the exact replacement for the 3 Ah battery fitted as standard to many power wheelchairs and mobility scooters.

• Approved for air and sea transport (VRLA).
• No maintenance, no water top-ups.
• Sealed AGM/GEL: safe indoors and in transport.
• AGM: faster recharging and better cycle resistance than a conventional battery.

What the Kronobat ES3-12 is for

With 3 Ah, the Kronobat ES3-12 offers the daily range that power wheelchairs, mobility scooters and light electric vehicles need, with a sealed construction that is safe indoors. Check that it matches your current battery in dimensions, terminals and hold-down: this reference has a weight of 1.30 kg and F1 terminals.

Will it fit your current battery tray?

The Kronobat ES3-12 is made in the 134 × 67 × 65 mm format and weighs 1.30 kg. It uses F1 terminals, the system that anchors and connects it in the vehicle. Checking the three dimensions and the terminal position before buying avoids the most common mistake when replacing a battery.

The Kronobat ES3-12: AGM Deep Cycle range and AGM technology

The AGM Deep Cycle is the Kronobat range the ES3-12 belongs to: it shares the same construction and quality criteria with the rest of the series, and varies in capacity and format to suit each vehicle.

In an AGM battery the electrolyte is absorbed in glass-fibre separators: there is no free liquid, it cannot spill and it can be mounted at an angle. That construction lowers internal resistance, speeds up recharging and multiplies cycle life compared with a conventional battery.

Care and maintenance

Use the original charger or one compatible with the battery technology (AGM/GEL) and always replace both batteries in the set together. Recharge the wheelchair or scooter after each use and do not leave it discharged for days: lead sulphates and loses capacity.

Warranty and coverage

The Kronobat ES3-12 comes with the manufacturer's official warranty against manufacturing defects. If it fails through a defect within the warranty period, we replace it at no cost to you.

Delivery times and returns

Same-day dispatch from our warehouse for in-stock orders placed before 6:00 pm: 24-48 working hours in mainland Spain and Portugal, 3 to 5 days in the islands and the rest of Europe.
