The Trojan SAGM 12 205: 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 12 205 is the 205 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.
Trojan: the maker behind the SAGM 12 205
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.
Manufacturer's warranty
The Trojan SAGM 12 205 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.
Care and maintenance
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.
