Measuring 689 × 265 × 610 mm, it is the direct replacement for off-grid PV systems fitted from the factory with a 942 Ah battery of this format.
- Good balance of capacity, cranking power and price.
- Low self-discharge during the darker months.
- Maintenance-free in off-grid installations.
- Compatible with common MPPT and PWM controllers.

### Size, terminals and hold-down of the Trojan SIND 06 1225

In terms of format, the Trojan SIND 06 1225 measures 689 × 265 × 610 mm (length × width × height) and weighs 188 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 Trojan SIND 06 1225 is for

Designed for off-grid photovoltaic installations and storage systems, the Trojan SIND 06 1225 tolerates extreme temperatures and long periods of low activity. Check that it matches your current battery in dimensions, terminals and hold-down: this reference has a weight of 188 kg.

### The Trojan SIND 06 1225: Industrial Energia Renovable - Smart Car range and conventional lead-acid technology

The **Industrial Energia Renovable - Smart Car** is the Trojan range the SIND 06 1225 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 a conventional battery the electrolyte is liquid and the lead plates are immersed in it. It is a mature, economical and easily recycled technology, ideal for starting vehicles in normal use.

### Why choose Trojan batteries

Trojan Battery is the world reference in deep-cycle batteries: golf carts, cleaning machines, aerial platforms and solar systems rely on its T2 technology and longevity. We guarantee that every Trojan arrives new, charged and with the manufacturer's full warranty.

### Manufacturer's warranty

The Trojan SIND 06 1225 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

Size the installation so as not to discharge the battery more than 50% daily and set the controller to the battery technology. On batteries with filler caps, check the electrolyte level and top up only with distilled water.

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

Orders placed **before 6:00 pm** 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 **14 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

### How is the Trojan SIND 06 1225 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 Trojan SIND 06 1225 battery last?

Expected lifespan of the Trojan SIND 06 1225 is 4 to 6 years in regular device use without 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 Trojan SIND 06 1225 battery?

Dimensions (length × width × height) are 689×265×610 mm — also written as 689x265x610 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 Trojan SIND 06 1225?

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.
