The Trojan T105-AGM in practice
T105-AGM vs Trojan SAGM 06 220
The Trojan T105-AGM offers 217 Ah and 0 A cold cranking in a 262 × 179 × 273 mm case. The Trojan SAGM 06 220, same brand and technology, goes up to 220 Ah and 0 A and costs €51.90 more. Going up is only worth it if the tray allows it and the car cranks lazily in the cold; in normal use this one is plenty.

Solar battery Trojan T105-AGM AGM Reliant 217Ah 6V
The Trojan T105-AGM with AGM technology stores 217 Ah at 6 V for off-grid photovoltaic installations and storage systems. Measuring 262 × 179 × 273 mm, it is the direct replacement for off-grid PV systems fitted from the factory with a 217 Ah battery of this format.
- AGM: faster recharging and better cycle resistance than a conventional battery.
- Low self-discharge during the darker months.
- Maintenance-free in off-grid installations.
- Compatible with common MPPT and PWM controllers.
Will it fit your current battery tray?
In terms of format, the Trojan T105-AGM measures 262 × 179 × 273 mm (length × width × height) and weighs 31 kg. It uses 5 8 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 the Trojan T105-AGM is for
With 217 Ah, the Trojan T105-AGM stores the energy from your panels for the night and cloudy days. Check that it matches your current battery in dimensions, terminals and hold-down: this reference has a weight of 31 kg and 5 8 15 terminals.
The Trojan T105-AGM: AGM Reliant range and AGM technology
The T105-AGM is part of the Trojan AGM Reliant range. Choosing the right reference within the series comes down to capacity, dimensions and terminals: technology and quality are common to the whole family.
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.
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. We guarantee that every Trojan arrives new, charged and with the manufacturer's full warranty.
Manufacturer's warranty
The Trojan T105-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
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.
When you get it and how to return it
Orders placed before 6:00 pm with the battery in stock ship the same day. Delivery in mainland Spain and Portugal takes 24-48 working hours; for the Balearic Islands and the rest of the European Union allow 3 to 5 working days. You have 14 days to return an unused battery; in mainland Spain and Portugal collection is free. We email you the tracking number as soon as the parcel ships.

Frequently asked questions
Is the T105-AGM model AGM? What does this technology offer?
Yes, it is AGM. In an AGM battery such as the T105-AGM, the electrolyte is not free but absorbed in a glass-fibre mat inside a sealed lead-acid battery. Compared with a conventional battery it withstands more charge/discharge cycles and handles heat better.
What size is this battery?
It measures 262×179×273 mm in length × width × height, with the terminals included in the height. Measure the battery tray before ordering: a one-millimetre difference is enough for the hold-down clamp not to close.
Trojan T105-AGM or Trojan SAGM 06 220: which one to choose?
Same case and same technology as the T105-AGM: an alternative by size, not an official equivalent. Compared with the T105-AGM it has 3 Ah more. It costs 51,90 € more. If the polarity matches and your equipment had a similar capacity, it works as a replacement; if in doubt, ask us with your model.
