The **Cyclon 6V-D** with AGM technology is a **2.5 Ah**, **6 V** backup battery for UPS, alarms, telecoms and emergency lighting. It measures 11 × 11 × 4 mm, the format sought by anyone replacing a 2.5 Ah battery in UPS, alarm and emergency systems.
- Long float life under permanent charge.
- AGM technology: absorbed electrolyte, no spills, can be mounted at an angle.
- Maintenance-free for its whole service life.
- Sealed and gas-free: suitable for cabinets and offices.

### What the Cyclon 6V-D is for

Designed for UPS, alarms, telecoms and emergency lighting, the Cyclon 6V-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 0.52 kg.

### Size, terminals and hold-down of the Cyclon 6V-D

The Cyclon 6V-D is made in the 11 × 11 × 4 mm format and weighs 0.52 kg. Checking the three dimensions and the terminal position before buying avoids the most common mistake when replacing a battery.

### The Cyclon 6V-D: Battery 6V Monoblocs range and AGM technology

Within the Cyclon catalogue, the **Battery 6V Monoblocs** series groups the references designed for this use. The 6V-D is the 2.5 Ah model of that family, with the same performance as its siblings in other sizes.
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.

### Cyclon: the maker behind the 6V-D

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. All the Cyclon batteries in our catalogue are genuine product, recently manufactured and covered by the manufacturer's warranty.

### Warranty and coverage

The Cyclon 6V-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.

### Usage and maintenance tips

Replace all the batteries in the set at once and avoid environments continuously above 25 °C. Check the float voltage of the UPS or charger: a voltage that is too high shortens the life of a sealed battery.

### When you get it and how to return it

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 6V-D an AGM battery and what are the benefits of AGM?

Yes. The 6V-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 is the Cyclon 6V-D 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 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.

### How long does the Cyclon 6V-D battery last?

Expected lifespan of the Cyclon 6V-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 are the dimensions of the Cyclon 6V-D battery?

Dimensions (length × width × height) are 11×11×5 mm — also written as 11x11x5 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.

### Which batteries are equivalent to the Cyclon 6V-D?

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.
