## Description

## Who the Tudor TA770 is for

The Tudor TA770 is a starter battery for cars without Start-Stop: it delivers the current the starter motor needs and then powers lights, control units and audio with the engine off. If your car has no Start-Stop and had a 77 Ah battery, the TA770 is a direct replacement.
At 77 Ah it sits in the range of compact and mid-size diesels, SUVs and MPVs. The TA770 belongs to the Tudor TUDOR HIGH TECH range. [See all Tudor batteries](https://bateriasonline.es/en/tudor-batteries)

## What to look at before buying the TA770

- Length, width and height of the TA770: 278 × 175 × 190 mm (European case size L3).
- With the terminals facing you, the positive terminal of the TA770 is on the right.
- Capacity of the TA770: 77 Ah; the same as your current battery or slightly more is fine.
- Check the EN amps on your battery: if it says 760 A or less, the TA770 covers your engine.
- If your car has Start-Stop, the TA770 is not the right one: it needs an EFB or an AGM.

## What it means that the TA770 is lead-acid

The TA770 is a conventional lead-acid battery, with plates immersed in liquid electrolyte. Avoid leaving them discharged, as they sulphate, and charge them with a charger that cuts off or switches to maintenance when finished.
