Batteries 80 A / h at 12 V

When choosing a battery, you need to build on the power of the car and its electrical equipment. If you put a battery of lower power, then it may not be enough to start the engine or it will not pull all the electrical equipment, and if it is larger, the generator will not be able to fully charge it. The battery at 80 a / h is considered quite capacious, so they are equipped with large sedans and crossovers.

How much does a battery weigh 80 a / h

Different manufacturers will have a lot of different masses, the thing is that each company uses its own unique technologies. Someone uses more lead plates, this makes the battery heavier, while less electrolyte is placed in it.

Other manufacturers, on the contrary, put fewer plates, the distance between them increases, and the volume of the filled electrolyte increases. You can immediately make a reservation that batteries in which more lead is better. They have a higher cold scroll current.

Therefore, weight is of great importance. With one capacity of 80 a / h, a higher quality battery will be one that is heavier. On average, an ordinary flooded battery at 80 A / h weighs 18-20 kg. If it is made according to AGM or EFB technology - 21.5-24 kg.

Battery Dimensions and Terminal Options

In Russia, batteries are available for sale for European cars with standard terminals, for Asian cars with ASIA terminals. You can distinguish them as follows. Asian terminals are already protruding above the case, and European ones are thicker and aligned flush with the battery cover. There are still batteries with an American terminal arrangement, but in Russia they are found only on cars driven from the USA.

With dimensions, everything is a little more complicated. For both Asian and European cars, there are two body options. In size, they will vary significantly. If you make a mistake when choosing, then the battery will either not fit into the seat, it will hang out.

All batteries can be either direct or reverse polarity.

How much electrolyte in the battery is 80 a / h

In these batteries, as in all other starter batteries, there are six cans (6CT-80). From 660 to 900 ml of electrolyte is placed in each jar. Everything here also depends on the manufacturer, as mentioned earlier, someone has more lead plates, and someone has less. It turns out that for a full charge of the battery at 80 A / h it will take from 4 to 5.4 liters.

By the way, if you have an AGM or EFB battery, then they do not have liquid electrolyte. Therefore, they do not need to be filled in at all. An exception is dry-charged batteries. These are those that are supplied without electrolyte. They will have to refuel yourself.

What current to charge the battery 80 a / h

With a working battery, current is supplied at a rate of 10% of its capacity. Since in our case the capacity is 80 a / h, it means that the current must be set to 8 Amps. If the battery recovers after a deep discharge, then first the current is set in the region of 2 amperes.

When applying higher currents, the battery will charge much faster, but in this case, the toxic electrolyte begins to boil and evaporate. This will lead to exposure of the plates and their shedding. So it is not recommended to charge with high currents.

For which cars is the battery 80 a / h suitable

Despite the importance of battery size, the most important characteristics are the capacity and inrush current. The capacity is selected relative to the type of fuel and engine displacement and at 80 a / h is suitable for you in the following cases:

• Carburetor engine - from 3 to 4 liters;
• Injection motor - from 3 to 3.5 liters;
• Diesel engine - from 2.6 to 3 liters.

Starting current is no less important, especially if the car is operated in places where there are cold winters. In this case, you need to choose with the highest possible value.

For vehicles equipped with a Start-Stop system, it is necessary to choose a power source made using AGM or EFB technology. Another advantage can be attributed to resistance to deep discharges.

Which battery for 80 a / h to choose and what to look for

First of all, you need to build on the size and type of battery. An Asian battery will not fit into the seat of a European car and vice versa. In addition, as mentioned earlier, each type has two sizes.

After that, we look at the polarity, since all manufacturers produce both direct and reverse polarity. If you have a car with a start-stop system, then it must be AGM, EFB or GEL. Beginners are advised to install maintenance-free batteries, although low-maintenance ones are also not particularly picky. Starting current the higher, the easier it is to start in winter.

In order not to stumble on a fake, you should purchase a battery in well-known retail chains from popular manufacturers, for example:

This is an approximate list, of course there are more quality copies, it is not recommended to purchase from dubious Chinese unknown companies, since they usually have overestimated figures.

Did you have or have 80 Ah battery? Then tell us in the comments which one and about your impressions about him, this will greatly help other motorists and will make the material more complete and accurate.

I took a Varta battery with a volume of 80 amperes / hour 12 v for my SUV. There are no complaints about work. The warranty was given for a year, but the unit has been working for about two years. Auto starts beautifully in the cold. The battery performed well.

For a lightweight car, the seller in the car shop advised me to buy a Bosch battery for 80 a / h. In general, satisfied with the purchase. The battery is high-quality, works without problems in any conditions.
