The Trojan SAGM 12 105 in practice
SAGM 12 105 vs Trojan OverDrive AGM 31
The Trojan SAGM 12 105 offers 105 Ah and 0 A cold cranking in a 325 × 173 × 237 mm case. The Trojan OverDrive AGM 31, same brand and technology, stays at 102 Ah and 0 A with 16 mm more length and costs €75.75 less. If your car originally had the smaller capacity, this one gives extra reserve in the same case.

What the Trojan SAGM 12 105 is for
With 105 Ah, the Trojan SAGM 12 105 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 30 kg.
The Trojan SAGM 12 105: Solar AGM - 1700 Ciclos 50% DOD range and AGM technology
Within the Trojan catalogue, the Solar AGM - 1700 Ciclos 50% DOD series groups the references designed for this use. The SAGM 12 105 is the 105 Ah model of that family, with the same performance as its siblings in other sizes.
In an AGM battery the electrolyte is absorbed in glass-fibre separators: there is no free liquid, it cannot spill and it can be mounted at an angle. That construction lowers internal resistance, speeds up recharging and multiplies cycle life compared with a conventional battery.
Dimensions, polarity and mounting
In terms of format, the Trojan SAGM 12 105 measures 325 × 173 × 237 mm (length × width × height) and weighs 30 kg. 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.

Frequently asked questions
Is the SAGM 12 105 model AGM? What does this technology offer?
Yes. The SAGM 12 105 from Trojan uses AGM (Absorbent Glass Mat) technology: a sealed lead-acid battery where the electrolyte is absorbed in a glass-fibre mat. It withstands more charge/discharge cycles than a conventional one, handles heat better and is the required technology for devices with advanced Start-Stop and regenerative braking. Expected lifespan: 5-8 years under normal conditions.
What are the dimensions of the Trojan SAGM 12 105 battery?
Dimensions (length × width × height) are 325×173×237 mm — also written as 325x173x237 mm — following the European DIN standard. Always measure the space in your device before buying: even one extra millimetre can prevent the hold-down clamp from closing. The height shown includes the terminals.
Trojan SAGM 12 105 or Trojan 31-AGM SV: which one to choose?
It has the same dimensions, voltage and technology as the SAGM 12 105, although it is not a manufacturer-approved equivalent. Compared with the SAGM 12 105 it has 5 Ah less. It costs 53,80 € less. Check the positive terminal side and the original capacity before ordering; otherwise it is a straight swap.
