## Description

## Stationary battery Cyclon 2V-D Battery 2V Single Cell 2.5Ah 2V

2*V* Voltage
2.5*Ah* Capacity
0.18*kg* Weight

Designed for UPS, alarms, telecoms and emergency lighting, the **Cyclon 2V-D** from the **Battery 2V Single Cell** range offers **2.5 Ah** with AGM technology on permanent float charge. It replaces the original battery without adaptation in UPS, alarm and emergency systems with a 34 × 34 × 6 mm format: same 2.5 Ah capacity.
- Sealed and gas-free: suitable for cabinets and offices.
- Maintenance-free for its whole service life.
- AGM technology: absorbed electrolyte, no spills, can be mounted at an angle.
- Long float life under permanent charge.

### Will it fit your current battery tray?

It has external dimensions of 34 × 34 × 6 mm and weighs 0.18 kg. Before replacing it, measure your current battery tray: if all three dimensions and the terminal positions match, the swap is direct and needs no adapters.

### What the Cyclon 2V-D is for

Designed for UPS, alarms, telecoms and emergency lighting, the Cyclon 2V-D is sealed, gas-free and suitable for technical cabinets and offices. Check that it matches your current battery in dimensions, terminals and hold-down: this reference has a weight of 0.18 kg.

### The Cyclon 2V-D: Battery 2V Single Cell range and AGM technology

The 2V-D is part of the Cyclon **Battery 2V Single Cell** range. Choosing the right reference within the series comes down to capacity, dimensions and terminals: technology and quality are common to the whole family.
AGM (Absorbent Glass Mat) technology seals the electrolyte in glass microfibre. The result is a maintenance-free battery that is highly vibration-resistant and able to withstand deep discharges that would ruin a classic lead-acid battery.

### What Cyclon does differently

Cyclon (EnerSys) makes pure-lead cells with thin plates wound in a spiral: high current, great tolerance to extreme temperatures and a very long life in industrial, military and emergency applications. We guarantee that every Cyclon arrives new, charged and with the manufacturer's full warranty.

### Warranty and coverage

The Cyclon 2V-D 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.

### Care and maintenance

Charge with a charger that has an AGM mode: it limits the voltage and protects the glass-fibre separators. Replace all the batteries in the set at once and avoid environments continuously above 25 °C.

### Shipping, delivery and returns

Same-day dispatch from our warehouse for in-stock orders placed **before [[ks:cutoff]]**: 24-48 working hours in mainland Spain and Portugal, 3 to 5 days in the islands and the rest of Europe. Returns are accepted for **[[ks:return_days]] days** if the battery has not been used (free collection on the Iberian mainland). You will receive tracking by email.

## Frequently asked questions

### Is the Cyclon 2V-D an AGM battery and what are the benefits of AGM?

Yes. The 2V-D from Cyclon 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 do I change this battery step by step?

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 this page. 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.

### What is the service life of the 2V-D model?

Expected lifespan of the Cyclon 2V-D 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 size is this battery?

Dimensions (length × width × height) are 34×34×61 mm — also written as 34x34x61 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 2V-D 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.
