The **6 V**, **330 Ah** **Trojan J305P-AC** from the **ciclo profundo - T2 Technology** range with conventional lead-acid technology is designed for golf carts and electric utility vehicles. Measuring 296 × 176 × 366 mm, it is the direct replacement for golf carts fitted from the factory with a 330 Ah battery of this format.
- Long service life in daily duty cycles.
- Standard format for golf carts and utility vehicles.
- Good balance of capacity, cranking power and price.
- Reinforced plate construction for intensive use.

### What the Trojan J305P-AC is for

With 330 Ah, the Trojan J305P-AC forms part of the battery banks of golf carts and electric utility vehicles. Always replace the complete set to avoid imbalance. Check that it matches your current battery in dimensions, terminals and hold-down: this reference has a weight of 44 kg and 6 terminals.

### Size, terminals and hold-down of the Trojan J305P-AC

The Trojan J305P-AC is made in the 296 × 176 × 366 mm format and weighs 44 kg. It uses 6 terminals, the system that anchors and connects it in the vehicle. 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.

### The Trojan J305P-AC: ciclo profundo - T2 Technology range and conventional lead-acid technology

The **ciclo profundo - T2 Technology** is the Trojan range the J305P-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.

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

### Warranty and coverage

The Trojan J305P-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.

### Usage and maintenance tips

Recharge the set fully after each round and avoid routine discharges below 20%. On batteries with filler caps, check the electrolyte level and top up only with distilled water.

### Shipping, delivery and returns

Same-day dispatch from our warehouse for in-stock orders placed **before [[ks:cutoff]]**: 24-48 working hours in mainland Spain and Portugal, 3 to 5 days in the islands and the rest of Europe. Returns are accepted for **[[ks:return_days]] days** if the battery has not been used (free collection on the Iberian mainland). You will receive tracking by email.

## Frequently asked questions

### How is the Trojan J305P-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 this page. 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 J305P-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 J305P-AC model?

Dimensions (length × width × height) are 296×176×366 mm — also written as 296x176x366 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 J305P-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.
