Solar battery Trojan 8D-GEL 225Ah 12V

The 12 V, 225 Ah Trojan 8D-GEL solar battery with GEL technology is designed for off-grid photovoltaic installations and storage systems. It measures 534 × 279 × 233 mm, the format sought by anyone replacing a 225 Ah battery in off-grid PV systems.

• Long life on float and moderate cycling.
• Good tolerance to extreme temperatures.
• Optimised for daily charge and discharge cycles.
• GEL technology: gelled electrolyte, fully sealed and maintenance-free.

What the Trojan 8D-GEL is for

The Trojan 8D-GEL is designed for off-grid photovoltaic installations and storage systems. Size the capacity so as not to discharge more than 50% daily and you will greatly extend its life. Check that it matches your current battery in dimensions, terminals and hold-down: this reference has a weight of 71 kg and 5 terminals.

Technology inside the Trojan 8D-GEL

The 8D-GEL 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.

A GEL battery is the choice when cycle resistance and safety matter most: no gases, no liquid and thousands of partial discharges in its lifetime.

Size, terminals and hold-down of the Trojan 8D-GEL

It has external dimensions of 534 × 279 × 233 mm and weighs 71 kg. It uses 5 terminals, the system that anchors and connects it in the vehicle. For a direct replacement, the current battery tray must accept these dimensions and the same terminal layout; otherwise adapters will be needed or the hold-down will change.

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. At baterias.com we work directly with the manufacturer or its official distributor: real stock, brand-new product and official warranty.

Care and maintenance

GEL batteries need lower charging voltages: always use a charger with a GEL mode so as not to damage the electrolyte. In the darker months, check the voltage periodically and avoid full discharges.

Warranty and coverage

The Trojan 8D-GEL 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.
