The **12 V**, **89 Ah** **Trojan 27-AGM** solar battery with AGM technology is designed for off-grid photovoltaic installations and storage systems. It measures 306 × 174 × 237 mm, the format sought by anyone replacing a 89 Ah battery in off-grid PV systems.
- Optimised for daily charge and discharge cycles.
- AGM technology: absorbed electrolyte, no spills, can be mounted at an angle.
- Long life on float and moderate cycling.
- Good tolerance to extreme temperatures.

### What the Trojan 27-AGM is for

Designed for off-grid photovoltaic installations and storage systems, the Trojan 27-AGM 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 29 kg and 6 terminals.

### Size, terminals and hold-down of the Trojan 27-AGM

The Trojan 27-AGM is made in the 306 × 174 × 237 mm format and weighs 29 kg. It uses 6 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.

### Technology inside the Trojan 27-AGM

The 27-AGM is one of the Trojan references for this type of use; it shares the same manufacturing and quality-control criteria as the rest of the brand's catalogue.
AGM means the acid is held in a glass mat instead of floating free. That is why the battery can be installed in the cabin without gases, survives more cycles and recovers its charge quickly.

### What Trojan does differently

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

### Warranty and coverage

The Trojan 27-AGM 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

In the darker months, check the voltage periodically and avoid full discharges. Size the installation so as not to discharge the battery more than 50% daily and set the controller to the battery technology.

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

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. Returns are accepted for **14 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 Trojan 27-AGM an AGM battery and what are the benefits of AGM?

Yes. AGM (Absorbent Glass Mat) technology, 89 Ah and 12 V: sealed lead-acid, with the electrolyte held in glass fibre. It tolerates heat better and handles more cycles than a conventional battery.

### What are the dimensions of the Trojan 27-AGM battery?

Length × width × height: 306x174x237 mm. Height is measured to the top of the terminals. Measure your device's battery tray first; if the battery exceeds it by even a millimetre, the hold-down clamp may not close.
