The Trojan J305-AES: Aes range and AGM technology

The Aes is the Trojan range the J305-AES belongs to: it shares the same construction and quality criteria with the rest of the series, and varies in capacity and format to suit each vehicle.

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. At baterias.com we work directly with the manufacturer or its official distributor: real stock, brand-new product and official warranty.

Official warranty

The Trojan J305-AES 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.

How to make it last longer

Always replace all the batteries in the bank at once and use the charger specified by the vehicle manufacturer. Charge with a charger that has an AGM mode: it limits the voltage and protects the glass-fibre separators.
