Frequently Asked Questions

Buying a battery on telebaterias.com has the following advantages:

  1. First of all, the price. Buying a battery online is much cheaper than buying a battery in a physical store, mainly thanks to our high sales volume.
  2. On the other hand, at telebaterias.com we have commercial agreements with the main battery manufacturers. Thanks to our high turnover, our products are stored for a few days at the factory and reach our customers in the best possible condition. Our batteries therefore have the most recent date of manufacture.
  3. Finally, thanks to our professional technical advice, you can change your battery yourself at the best price

To find out if a battery is suitable for my vehicle, the best thing to do is to contrast the characteristics of the battery we have installed with the one we are going to buy.

Battery technology.

First of all, we must check that the type of battery is compatible with the one we are going to buy. If the technology is special, it is usually indicated on the battery. Battery technology is especially relevant in vehicles equipped with a start-stop system.

Measurements.

It is very important that the battery enters the cabin prepared for installation. Keep in mind that the measurements of the batteries are the maximum measurements of the same with all its edges, with the height of the terminal, with the tab for fastening, etc ... Therefore, if you have the appropriate gap for the measurement battery, you will have no problem installing it. In many cases you will see that you have a larger gap to install a larger battery. In these cases, we recommend that you put the battery with the highest amperage that fits into the hole.

Arrangement of the terminals.

It is essential that the positive of the battery matches the location of the positive of the battery you have installed. The convention is to locate the positive being as close as possible to the terminals, since in some cases, the battery may have the terminals closest to the conductor and in other cases closer to the license plate.

However, if you look closely at the photo you can see if the positive of the battery matches the one you have.

In general, except for Asian, American or some off-road vehicles, it is normal for the positive to be on the right.

This is a general guide. However, if you have any questions, contact us and we will be happy to advise you on the most suitable battery for your vehicle.

GB251+ by NOCO: Boost MAX 24V 3000A lithium jump starter

Will it work on a 24V lorry? That is exactly its job: the GB251+ starts 24V lead-acid systems with 3000A peak current and handles petrol and diesel engines up to 32 L, so Class 8 trucks, buses, motorhomes and plant machinery are covered.

Before you clamp on, the built-in voltmeter shows the battery voltage. It detects batteries from 3V, with a manual override below that, and a 60-second timer protects the 137 Wh internal charge.

The box includes an EVA case, the XGC4 mains adapter and a 12V vehicle cable; a full recharge takes around 8.5 hours.

  • ›  Engine displacement is no more than 32 L, petrol or diesel.
  • ›  The battery is lead-acid: flooded, gel, MF, EFB or AGM.
  • ›  You can recharge it from the XGC4 adapter or a 12V vehicle socket.
  • ›  Not sure about your truck or machine? Give us a call and we will confirm the model before you order.
