## Varta T14B-BS vs YTX14-BS and T12B-BS

How the T14B-BS compares with Varta batteries of similar size and capacity:

| Model | Capacity | Cold cranking (EN) | Dimensions (mm) | Positive | Weight |
|---|---|---|---|---|---|
| Varta T14B-BS (this one) | 12 Ah | 190 A | 152 × 70 × 145 | left | 4.11 kg |
| Varta YTX14-BS | 12 Ah | 200 A | 152 × 88 × 147 | left | 4.37 kg |
| Varta T12B-BS | 10 Ah | 160 A | 151 × 70 × 131 | left | 3.55 kg |

- Varta YTX14-BS: the same capacity, 10 A more cranking power, a different case (152 × 88 × 147 mm).
- Varta T12B-BS: 2 Ah less, 30 A less cranking power, a different case (151 × 70 × 131 mm).

## Before ordering the T14B-BS, check this

- Check the EN amps on your battery: if it says 190 A or less, the T14B-BS covers your engine.
- With 12 Ah, the T14B-BS replaces an original battery of that capacity or slightly less.
- Polarity of the T14B-BS: positive terminal on the left (if yours has it on the other side, the cables will not reach).
- The T14B-BS needs 152 × 70 × 145 mm of space: measure it with the hold-down clamp in place.

## Frequently asked questions about the Varta T14B-BS

### T14B-BS or YTX14-BS: which one suits me?

Compared with the T14B-BS, the Varta YTX14-BS has 10 A more cranking power. If your current battery says 200 A or more, choose the YTX14-BS; if it says 190 A or less, the T14B-BS is enough. Mind the space: the YTX14-BS measures 152 × 88 × 147 mm.

### Is the Varta 512903019 the same battery as the Varta T14B-BS?

Yes. 512903019 is the ETN code Varta uses for its T14B-BS battery, so you can search for it by either code.

### How much does the Varta T14B-BS weigh?

4.11 kg, with 12 Ah of capacity. For reference, the Varta YTX14-BS (12 Ah) weighs 4.37 kg.

### Which battery is equivalent to the Varta T14B-BS?

Only other AGM batteries with its dimensions and polarity: Exide ET14B-BS and Motobatt MBT14B4. Neither an EFB nor a conventional battery replaces the T14B-BS.

### Which side is the positive terminal on the Varta T14B-BS?

On the T14B-BS, 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 Varta T14B-BS 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.

## Inside the T14B-BS: AGM technology

Inside, the T14B-BS has glass fibre separators (AGM) that hold the electrolyte. It is fitted in cars with advanced Start-Stop and in deep-cycle equipment.
