## Trojan T1275-AES vs 5SHP-AES and J185-AES: differences

Torn between the T1275-AES and another similar Trojan? This is what changes:

| Model | Capacity | Dimensions (mm) | Weight |
|---|---|---|---|
| Trojan T1275-AES (this one) | 146 Ah | 329 × 179 × 278 | 48 kg |
| Trojan 5SHP-AES | 130 Ah | 341 × 170 × 263 | 44 kg |
| Trojan J185-AES | 175 Ah | 380 × 176 × 367 | 57 kg |

- Trojan 5SHP-AES: 16 Ah less, a different case (341 × 170 × 263 mm).
- Trojan J185-AES: 29 Ah more, a different case (380 × 176 × 367 mm).

## Inside the T1275-AES: AGM technology

The T1275-AES is AGM: the electrolyte is absorbed in glass fibre mats, so it is sealed and spill-proof. It withstands many more cycles than a conventional lead battery, at the cost of being more sensitive to overcharging.

## What to look at before buying the T1275-AES

- Measure the space: the T1275-AES takes up 329 × 179 × 278 mm.
- Capacity of the T1275-AES: 146 Ah; the same as your current battery or slightly more is fine.

## Frequently asked questions about the Trojan T1275-AES

### T1275-AES or 5SHP-AES: which one suits me?

Compared with the T1275-AES, the Trojan 5SHP-AES has 16 Ah less. With 146 Ah, the T1275-AES runs longer between charges than the 5SHP-AES (130 Ah). Mind the space: the 5SHP-AES measures 341 × 170 × 263 mm.

### How much does the Trojan T1275-AES weigh?

48 kg, with 146 Ah of capacity. For reference, the Trojan 5SHP-AES (130 Ah) weighs 44 kg.

### Which battery is equivalent to the Trojan T1275-AES?

Only other AGM batteries with its dimensions and polarity: Ritar EV12-150S and Leoch LDC12-150-GC12. Neither an EFB nor a conventional battery replaces the T1275-AES.

### How many days of autonomy does the Trojan T1275-AES give in a motorhome?

It depends on consumption. With 146 Ah and LED lights, pump and a gas fridge, 2 or 3 days without recharging is normal; with an electric fridge, much less.
