## Exide AGM12-7.1 vs AGM12-7F and AGM12-7.5: which one to choose?

Torn between the AGM12-7.1 and another similar Exide? This is what changes:

| Model | Capacity | Cold cranking (EN) | Dimensions (mm) | Positive | Weight |
|---|---|---|---|---|---|
| Exide AGM12-7.1 (this one) | 8 Ah | 110 A | 150 × 70 × 105 | left | 2.8 kg |
| Exide AGM12-7F | 7 Ah | 85 A | 150 × 65 × 95 | – | 2.5 kg |
| Exide AGM12-7.5 | 8 Ah | 120 A | 150 × 90 × 105 | left | 3.1 kg |

- Exide AGM12-7F: 1 Ah less, 25 A less cranking power, a different case (150 × 65 × 95 mm).
- Exide AGM12-7.5: the same capacity, 10 A more cranking power, a different case (150 × 90 × 105 mm).

## Before ordering the AGM12-7.1, check this

- Cold cranking: 110 A (EN), equal to or higher than the original.
- Capacity of the AGM12-7.1: 8 Ah; the same as your current battery or slightly more is fine.
- Polarity of the AGM12-7.1: positive terminal on the left (if yours has it on the other side, the cables will not reach).
- Length, width and height of the AGM12-7.1: 150 × 70 × 105 mm.

## Frequently asked questions about the Exide AGM12-7.1

### AGM12-7.1 or AGM12-7F: which one suits me?

Compared with the AGM12-7.1, the Exide AGM12-7F has 1 Ah less and 25 A less cranking power. The AGM12-7.1 cranks harder; the AGM12-7F is only a good option if your original battery says 85 A or less. Mind the space: the AGM12-7F measures 150 × 65 × 95 mm.

### How much does the Exide AGM12-7.1 weigh?

2.8 kg, with 8 Ah of capacity. For reference, the Exide AGM12-7F (7 Ah) weighs 2.5 kg.

### Which battery is equivalent to the Exide AGM12-7.1?

Only other AGM batteries with its dimensions and polarity: Varta T9B (FA), Varta YT9B-BS and Motobatt MBT9B4. Neither an EFB nor a conventional battery replaces the AGM12-7.1.

### Which side is the positive terminal on the Exide AGM12-7.1?

On the AGM12-7.1, the positive terminal is on the left with the terminals facing you: compare it with your current battery, because with reversed polarity the cables will not reach.

### Which charger does the Exide AGM12-7.1 need?

A charger with an AGM mode that limits voltage to about 14.4-14.7 V. Never an old unregulated charger: overcharging dries out an AGM beyond repair.

## What it means that the AGM12-7.1 is AGM

Inside, the AGM12-7.1 has glass fibre separators (AGM) that hold the electrolyte. It is fitted in cars with advanced Start-Stop and in deep-cycle equipment.
