6*V* Voltage
305*Ah* Capacity
38*kg* Weight

The **6 V**, **305 Ah** **Trojan J305E-AC** from the **ciclo profundo - T2 Technology** range with conventional lead-acid technology is designed for golf carts and electric utility vehicles. Measuring 309 × 174 × 366 mm, it is the direct replacement for golf carts fitted from the factory with a 305 Ah battery of this format.
- Good balance of capacity, cranking power and price.
- Reinforced plate construction for intensive use.
- Long service life in daily duty cycles.
- Standard format for golf carts and utility vehicles.

### Dimensions, polarity and mounting

In terms of format, the Trojan J305E-AC measures 309 × 174 × 366 mm (length × width × height) and weighs 38 kg. It uses 4 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.

### What the Trojan J305E-AC is for

The Trojan J305E-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 38 kg and 4 terminals.

### The Trojan J305E-AC: ciclo profundo - T2 Technology range and conventional lead-acid technology

Within the Trojan catalogue, the **ciclo profundo - T2 Technology** series groups the references designed for this use. The J305E-AC is the 305 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.

### What Trojan does differently

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. We guarantee that every Trojan arrives new, charged and with the manufacturer's full warranty.

### Warranty and coverage

The Trojan J305E-AC 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. Recharge the set fully after each round and avoid routine discharges below 20%.

### When you get it and how to return it

Order **before 6:00 pm** with stock available and it leaves today: mainland Spain and Portugal receive it in 24-48 working hours, the islands and the rest of the EU in 3 to 5 days. You have **14 days** to return it if it has not been installed, with free collection on the mainland, and shipment tracking by email.

## Frequently asked questions

### How is the Trojan J305E-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 many years does this battery last?

Expected lifespan of the Trojan J305E-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 dimensions of the Trojan J305E-AC battery?

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.

### Which batteries are equivalent to the Trojan J305E-AC?

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.
