Solar battery Trojan SSIG 12 120 Solar Signatura 600 Ciclos 50% DOD 107Ah 12V
The Trojan SSIG 12 120 with conventional lead-acid technology stores 107 Ah at 12 V for off-grid photovoltaic installations and storage systems. Its 326 × 168 × 247 mm make it the exact replacement for the 107 Ah battery fitted as standard to many off-grid PV systems.
- Low self-discharge during the darker months.
- Good balance of capacity, cranking power and price.
- Compatible with common MPPT and PWM controllers.
- Maintenance-free in off-grid installations.
What the Trojan SSIG 12 120 is for
With 107 Ah, the Trojan SSIG 12 120 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 25 kg.
Dimensions, polarity and mounting
The Trojan SSIG 12 120 is made in the 326 × 168 × 247 mm format and weighs 25 kg. 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.
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. At baterias.com we work directly with the manufacturer or its official distributor: real stock, brand-new product and official warranty.
The Trojan SSIG 12 120: Solar Signatura 600 Ciclos 50% DOD range and conventional lead-acid technology
Within the Trojan catalogue, the Solar Signatura 600 Ciclos 50% DOD series groups the references designed for this use. The SSIG 12 120 is the 107 Ah model of that family, with the same performance as its siblings in other sizes.
Conventional lead-acid is the benchmark against which other technologies are compared: good cranking current, great tolerance to alternator charging and the best price per amp-hour.
How to make it last longer
In the darker months, check the voltage periodically and avoid full discharges. Size the installation so as not to discharge the battery more than 50% daily and set the controller to the battery technology.
Official warranty
The Trojan SSIG 12 120 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.

Frequently asked questions
How is the Trojan SSIG 12 120 battery installed in the vehicle?
In most devices it fits in 15-30 minutes with a 10 mm wrench; if the battery is under the seat or in the boot the time can double. See the step-by-step guide on our blog. Quick summary: 1) switch off the engine and remove the key; 2) locate the original battery (engine bay, boot or under seat); 3) disconnect the negative (−) terminal first, then the positive (+); 4) loosen the hold-down clamp and remove the old battery; 5) fit the new one in the same orientation — match the polarity shown on the product sheet; 6) connect the positive (+) first, then the negative (−). On devices with Start-Stop or BMS, register the battery via OBD so the alternator applies the correct charging profile.
What is the service life of the SSIG 12 120 model?
Expected lifespan of the Trojan SSIG 12 120 is 4 to 6 years in regular device use without Start-Stop. In cold regions it drops slightly due to cold-start stress; in very hot regions it also drops because of electrolyte evaporation. To extend its life: avoid deep discharges (headlights on with engine off), have the alternator checked yearly, and keep the battery clean and properly secured.
What are the dimensions of the Trojan SSIG 12 120 battery?
Dimensions (length × width × height) are 326×168×247 mm — also written as 326x168x247 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.
Which interchangeable batteries are there for this one?
Directly interchangeable batteries (same dimensions, same polarity, same Ah and CCA) are the OEM equivalents from leading brands: Bosch, Tudor, Exide and, depending on the model, Banner or Yuasa. Exact equivalence depends on technology — an EFB cannot be replaced with a conventional battery in Start-Stop devices. See the "Equivalents" section to view recommended options at the same performance level.
