Weight with batteries of different capacities – in the table we will consider a battery of 55, 60, 75, 190 Ah and others.

Few motorists in the process of operating the car, think about how the weight of the battery installed under the hood of the car. Even when buying power, they are more interested in other characteristics that directly affect the quality of the engine and avionics. The issue is that the weight of the battery comes out during car tuning, or when you try to take out the battery to a scrap yard. The easiest way to determine the weight of a battery is to weigh it. But there are other ways too. In this article, we will talk about the effect of battery capacity and weight and provide a table with which you can easily find the information you need.

What is the weight of the power supply

Some manufacturers, in good faith, all the parameters of the power supply on its case, including its severity. If you want, you can just look for a sticker with this information. However, a significant improvement in the engine, for example, you may encounter difficulties. The fact that the label on the cabinet indicates the mass of the dry battery, without electrolyte. The difference can reach 20%, and this is very important when tuning the engine.

In order not to make mistakes in the calculations, you should know that the final weight will consist of three components:

• corps;
• volume of electrolytic liquid;
• size and number of lead electrodes.

So, in a battery with a capacity of 55 ampere-hours (if the battery is ST-55 6), the plastic case, together with the jumpers between the banks, weighs about 800 g, and in the electrolyte solution it is 2.5 kg.

If you are on the sticker cabinet you will be able to see the cost of 11 kg, then this figure should be added 0.8 and 2.5. The total cost is 14.3 kg.

Few people want to spend time on calculations, so there is another way to calculate how much the battery weighs.

Power to weight table

As you know, the lion's share of the mass of the battery falls on the lead plates. The percentage is about 80%. To achieve a certain capacity, the manufacturer manipulates the number and size of the plates. Thus, knowing the battery parameter can easily calculate its gravity.

In this table, you can determine how heavy domestic or imported batteries are in minutes.

Summarizing

As you can see, it is not necessary to go to the scales to know the weight of the car battery, the table in our article will help you with this if this information was not on the product. With it, you will quickly recognize the great batteries with or without electrolyte.
