Trojan 12-AGM · Solar battery 12V 140Ah AGM

Solar battery Trojan 12-AGM 140Ah 12V

For off-grid photovoltaic installations and storage systems, the Trojan 12-AGM stores 140 Ah with AGM technology through daily charge and discharge cycles. Measuring 344 × 172 × 278 mm, it is the direct replacement for off-grid PV systems fitted from the factory with a 140 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.

Will it fit your current battery tray?

The Trojan 12-AGM is made in the 344 × 172 × 278 mm format and weighs 45 kg. It uses 15 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 the Trojan 12-AGM is for

The Trojan 12-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 45 kg and 15 terminals.

Technology inside the Trojan 12-AGM

Within the Trojan catalogue, the 12-AGM is the 140 Ah model designed for this application.

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.

Why choose Trojan batteries

Founded in 1925 in California, Trojan invented the golf cart battery and remains the standard in deep-discharge applications that demand thousands of cycles. All the Trojan batteries in our catalogue are genuine product, recently manufactured and covered by the manufacturer's warranty.

Official warranty

The Trojan 12-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

Charge with a charger that has an AGM mode: it limits the voltage and protects the glass-fibre separators. Size the installation so as not to discharge the battery more than 50% daily and set the controller to the battery technology.
