For each car you need to choose your own battery. This is due to the fact that everyone has different engines, electrical equipment and applied technologies. The battery at 90 a / h is one of the most powerful, as a rule it is equipped with SUVs and premium cars.

How much the battery weighs 90 a / h
The weight of the battery depends on the amount of lead used. The more lead in the plates, the higher the capacity. The 90 Ah batteries are very capacious, so they are quite heavy.
Weight is distributed like this:
- plastic - 5% - 7%;
- electrolyte - 16% - 20%;
- lead - 75% - 80% of the total mass of the product.
The total weight of the battery is 90 a / h with an electrolyte of approximately 23.1 kg and 20.5 kg without it. For some manufacturers, this indicator will be slightly larger, while for others it will be slightly less.
For example, Titan produces units weighing 21.2 kg, and Bost - 22.4 kg.
Battery Dimensions and Terminal Options
Given that lead-acid batteries with a capacity of 90 ampere hours are much more powerful than products with a capacity of 40 or 70 ampere hours, their dimensions are much larger. Here, manufacturers adhere to three standards: European, Asian and American.
| Standard | Long mm | Width mm | Height mm |
|---|---|---|---|
| European | 353 | 175 | 190 |
| Asian | 306 | 173 | 225 |
The sizes according to the American standard coincide with the European.
Given the different manufacturing standards, the battery terminals also differ. These elements are also of three types: standard - resemble the shape of a truncated cone, Asian are similar to standard, but slightly thinner in diameter and American - screw.
How much electrolyte in the battery is 90 a / h
Given the total weight of the battery with and without electrolyte, the volume of the liquid to be added is 16% - 20% of the total mass of the product, we can say that the electrolyte in such batteries is about 4.4 - 4.8 liters, about 6 kg 1 liter of electrolyte = 1.28 kg. Cans are not completely filled with electrolyte, there is always room for expansion of the liquid.
If you do not know how much electrolyte should be added, then focus on the fact that the liquid should cover the plates by 1-1.5 cm.
How to charge the battery 90 a / h
Any battery must be charged with a current that does not exceed 10% of the battery capacity. That is, if the capacity is 90 a / h, then the current should not be more than 9 amperes. If a higher current is applied, the battery will charge faster, but it will boil more, and since many premium batteries are maintenance-free, there will be no possibility to add water. After the plates are bare, they will crumble, and the battery will become worthless.
If you charge the battery with lower currents, it will be a more gentle mode, though it will take much more time, about two days.
What vehicles is the 90 a / h battery suitable for
Starter 12-volt batteries with a capacity of 90 ampere hour are suitable for cars and SUVs with powerful engines:
- Carburetor engine: 4.5 - 6.2 liters;
- Injection engines: 3.5 liters or more;
- Diesel engine: 2.7 - 3.5 liters.
Given the different types of terminals, the battery can be selected for Asian, European and American cars. It makes no sense to put such a powerful battery on a domestic author.
For vehicles equipped with a Start-Stop system, batteries made by technology are available Efb, Agm, GEL. There are both serviced models and maintenance free.
Which 90 a / h battery to choose and what to look for
First you need to decide on the type of case, the location of the terminals and dimensions. If the machine is equipped with a start-stop system, then you need to choose a battery made using EFB, AGM or GEl technology.The higher the cold scroll current (inrush current), the easier it will be to start in winter.
Next, it is important to choose the right reliable manufacturer, in this regard, the following brands have proven themselves: Bravo, Exide, Extra Start, Akom, AkTex, UNO, Varta, Tenax, Medalist, FB7000, Tyumen battery, BoschGlobatt Mutlu, Totachi, Gigawatt. Auto owners should also pay attention to the date of release of the product, the later it is, the worse and look at the warranty period.

Buying a second battery, I chose the Mutlu Calcium Silver 90 Ah LS5-90A. The advantages are obvious - the price is average, you can maintain, there are convenient handles to carry. It withstands a long load, in winter I take it off myself, charge it - no surprises for the seventh year now.

I often travel long distances for work, in winter - without a good battery - nowhere! When the old unit fell into disrepair, I bought an inexpensive Extra Start brand. There are no problems, I’ve been traveling for the third year, I’ve charged several times, and it works properly, I never let it down, even in severe frosts.
