What the Trojan J305HG-AC is for
The Trojan J305HG-AC is designed for golf carts and electric utility vehicles: deep discharges every day and a full overnight recharge. Check that it matches your current battery in dimensions, terminals and hold-down: this reference has a weight of 45 kg and 7 terminals.
The Trojan J305HG-AC: ciclo profundo - T2 Technology range and conventional lead-acid technology
The ciclo profundo - T2 Technology is the Trojan range the J305HG-AC 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.
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.
Will it fit your current battery tray?
In terms of format, the Trojan J305HG-AC measures 309 × 174 × 366 mm (length × width × height) and weighs 45 kg. It uses 7 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.

Frequently asked questions
How is the Trojan J305HG-AC 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.
How long does the Trojan J305HG-AC battery last?
Expected lifespan of the Trojan J305HG-AC 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 measurements of the J305HG-AC model?
Dimensions (length × width × height) are 309×174×366 mm — also written as 309x174x366 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.
What are the equivalents of the J305HG-AC model?
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.
