## Description

## Mobility battery Kronobat ES5-12 AGM Deep Cycle 5Ah 12V

12*V* Voltage
5*Ah* Capacity
1.90*kg* Weight

The **Kronobat ES5-12** with AGM technology delivers **5 Ah** at **12 V** with the cycle life that power wheelchairs, mobility scooters and light electric vehicles demand. Measuring 90 × 70 × 109 mm, it is the direct replacement for power wheelchairs and mobility scooters fitted from the factory with a 5 Ah battery of this format.
- No maintenance, no water top-ups.
- Approved for air and sea transport (VRLA).
- AGM: faster recharging and better cycle resistance than a conventional battery.
- Sealed AGM/GEL: safe indoors and in transport.

### What the Kronobat ES5-12 is for

The Kronobat ES5-12 is the usual replacement in power wheelchairs, mobility scooters and light electric vehicles. Recharge after each use and avoid leaving it discharged for days. Check that it matches your current battery in dimensions, terminals and hold-down: this reference has a weight of 1.90 kg and F1 / F2 terminals.

### Dimensions, polarity and mounting

In terms of format, the Kronobat ES5-12 measures 90 × 70 × 109 mm (length × width × height) and weighs 1.90 kg. It uses F1 / F2 terminals, the system that anchors and connects it in the vehicle. For a direct replacement, the current battery tray must accept these dimensions and the same terminal layout; otherwise adapters will be needed or the hold-down will change.

### The Kronobat ES5-12: AGM Deep Cycle range and AGM technology

Within the Kronobat catalogue, the **AGM Deep Cycle** series groups the references designed for this use. The ES5-12 is the 5 Ah model of that family, with the same performance as its siblings in other sizes.
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.

### What Kronobat does differently

Kronobat is the exclusive brand of baterias.com: batteries made to the same production standards as the leading brands, with a value for money that is hard to match and an official warranty. All the Kronobat batteries in our catalogue are genuine product, recently manufactured and covered by the manufacturer's warranty.

### Official warranty

The Kronobat ES5-12 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.

### How to make it last longer

Recharge the wheelchair or scooter after each use and do not leave it discharged for days: lead sulphates and loses capacity. Charge with a charger that has an AGM mode: it limits the voltage and protects the glass-fibre separators.

### Shipping, delivery and returns

Orders placed **before [[ks:cutoff]]** with the battery in stock ship the same day. Delivery in mainland Spain and Portugal takes 24-48 working hours; for the Balearic Islands and the rest of the European Union allow 3 to 5 working days. You have **[[ks:return_days]] days** to return an unused battery; in mainland Spain and Portugal collection is free. We email you the tracking number as soon as the parcel ships.

## Frequently asked questions

### Is the Kronobat ES5-12 an AGM battery and what are the benefits of AGM?

Yes. The ES5-12 from Kronobat uses AGM (Absorbent Glass Mat) technology: a sealed lead-acid battery where the electrolyte is absorbed in a glass-fibre mat. It withstands more charge/discharge cycles than a conventional one, handles heat better and is the required technology for devices with advanced Start-Stop and regenerative braking. Expected lifespan: 5-8 years under normal conditions.

### How is the Kronobat ES5-12 battery installed in the vehicle?

In most devices it fits in 15-30 minutes with a 10 mm wrench; if the battery is under the seat or in the boot the time can double. See the step-by-step guide on our blog. Quick summary: 1) switch off the engine and remove the key; 2) locate the original battery (engine bay, boot or under seat); 3) disconnect the negative (−) terminal first, then the positive (+); 4) loosen the hold-down clamp and remove the old battery; 5) fit the new one in the same orientation — match the polarity shown on the product sheet; 6) connect the positive (+) first, then the negative (−). On devices with Start-Stop or BMS, register the battery via OBD so the alternator applies the correct charging profile.

### How long does the Kronobat ES5-12 battery last?

Expected lifespan of the Kronobat ES5-12 is 5 to 8 years in mild-climate device use with Start-Stop. In cold regions it drops slightly due to cold-start stress; in very hot regions it also drops because of electrolyte evaporation. To extend its life: avoid deep discharges (headlights on with engine off), have the alternator checked yearly, and keep the battery clean and properly secured.

### What are the dimensions of the Kronobat ES5-12 battery?

Dimensions (length × width × height) are 90×70×109 mm — also written as 90x70x109 mm — following the European DIN standard. Always measure the space in your device before buying: even one extra millimetre can prevent the hold-down clamp from closing. The height shown includes the terminals.

### What are the equivalents of the ES5-12 model?

Directly interchangeable batteries (same dimensions, same polarity, same Ah and CCA) are the OEM equivalents from leading brands: Bosch, Tudor, Exide and, depending on the model, Banner or Yuasa. Exact equivalence depends on technology — an EFB cannot be replaced with a conventional battery in Start-Stop devices. See the "Equivalents" section to view recommended options at the same performance level.
