Trojan U1-AGM · Solar battery 33Ah AGM

Solar battery Trojan U1-AGM 33Ah 12V

The Trojan U1-AGM with AGM technology stores 33 Ah at 12 V for off-grid photovoltaic installations and storage systems. Measuring 198 × 132 × 171 mm, it is the direct replacement for off-grid PV systems fitted from the factory with a 33 Ah battery of this format.

• Maintenance-free in off-grid installations.
• Compatible with common MPPT and PWM controllers.
• AGM: faster recharging and better cycle resistance than a conventional battery.
• Low self-discharge during the darker months.

What the Trojan U1-AGM is for

The Trojan U1-AGM 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 12 kg and 15 terminals.

Technology inside the Trojan U1-AGM

Trojan builds the U1-AGM to the same standards as the rest of its catalogue; what changes between references is capacity, format and terminal position.

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.

Dimensions, polarity and mounting

In terms of format, the Trojan U1-AGM measures 198 × 132 × 171 mm (length × width × height) and weighs 12 kg. It uses 15 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.

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.

How to make it last longer

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 U1-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.
