## Description

## Where the Trojan J185E-AC fits

The Trojan J185E-AC drives electric work machines. It is installed in banks at the machine voltage and needs a charger with the right profile.
The J185E-AC belongs to the Trojan TROJAN deep cycle - T2 Technology range. [See all Trojan batteries](https://bateriasonline.es/en/trojan-batteries)

## Inside the J185E-AC: lead-acid technology

Inside, the J185E-AC is classic lead-acid: liquid electrolyte and lead plates. If the J185E-AC is left discharged for weeks it sulphates: a maintenance charger prevents this.

## Trojan J185E-AC vs J185G-AC and J185HG-AC: which one to choose?

How the J185E-AC compares with Trojan batteries of similar size and capacity:

| Model | Capacity | Dimensions (mm) | Weight |

## Frequently asked questions about the Trojan J185E-AC

### Trojan J185E-AC or J185G-AC?

Compared with the J185E-AC, the Trojan J185G-AC has 10 Ah more. With 185 Ah, the J185G-AC runs longer between charges than the J185E-AC (175 Ah). Both measure 391 × 175 × 386 mm, so they fit the same tray.

### How much does the Trojan J185E-AC weigh?

The J185E-AC weighs 46 kg. For reference, the Trojan J185G-AC (185 Ah) weighs 48 kg.

### Which battery is equivalent to the Trojan J185E-AC?

With the same dimensions, polarity and similar capacity you have the Trojan J185G-AC. As the J185E-AC is a conventional battery, an EFB or AGM of the same size also works.

### Which charger do I need?

One with the total bank voltage and a charge curve for the battery technology. A small charger will never fill it and will leave it sulphated.
