Trojan J305-AGM · Solar battery 6V 310Ah AGM

Solar battery Trojan J305-AGM AGM Reliant 310Ah 6V

For off-grid photovoltaic installations and storage systems, the Trojan J305-AGM from the AGM Reliant range stores 310 Ah with AGM technology through daily charge and discharge cycles. It replaces the original battery without adaptation in off-grid PV systems with a 296 × 176 × 358 mm format: same 310 Ah capacity.

• AGM technology: absorbed electrolyte, no spills, can be mounted at an angle.
• Optimised for daily charge and discharge cycles.
• Good tolerance to extreme temperatures.
• Long life on float and moderate cycling.

What the Trojan J305-AGM is for

Designed for off-grid photovoltaic installations and storage systems, the Trojan J305-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 44 kg and 5 6 15 terminals.

The Trojan J305-AGM: AGM Reliant range and AGM technology

Within the Trojan catalogue, the AGM Reliant series groups the references designed for this use. The J305-AGM is the 310 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.

Dimensions, polarity and mounting

The Trojan J305-AGM is made in the 296 × 176 × 358 mm format and weighs 44 kg. It uses 5 6 15 terminals, the system that anchors and connects it in the vehicle. 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 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.

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. Charge with a charger that has an AGM mode: it limits the voltage and protects the glass-fibre separators.

Official warranty

The Trojan J305-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.

Shipping, delivery and returns

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.
