Capacity is the main characteristic of a battery. Not always a large indicator of this value is necessary for the normal provision of any mechanism with electric current. The battery capacity is directly dependent on its mass and dimensions, therefore, for example, 45 Ah batteries are used for installation in small cars.

How much the battery weighs 45 Ah
Car battery plates are made of lead, which is a very heavy metal. Also in the battery there is a considerable amount of plastic and liquid, which is a solution of sulfuric acid (electrolyte).
The total weight is the weight of all these components and in the maximum value can reach 13.1 kg. The average weight of products with a capacity of 45 ah will be 12.1 kg.
Battery Dimensions and Terminal Options
Batteries with a capacity of 45 ampere hours are available in two versions: Standard and ASIA:
| Parameter | Standard | ASIA |
|---|---|---|
| Long mm | 238 | 207 |
| Width mm | 129 | 175 |
| Height mm | 227 | 195 |
Some manufacturers may have slightly different battery sizes. In addition to a slight difference in width and length, batteries of this type can have different terminal diameters. On sale you can find batteries with the following sizes:
- Asian: (+) - 12.7 mm; (-) - 11.1 mm.
- European: (+) - 19.5 mm; (-) - 17.5 mm.
- American: the terminals are internally threaded.
When buying a new battery, you should carefully select the product according to size and type of terminals.
How much electrolyte is in the battery 45 Ah
If the battery is supplied dry-charged, then car owners need to know exactly how much electrolyte is poured into cans. In a 6CT 45 battery, the total electrolyte volume will be ~ 2.5 liters. About 400 ml of liquid should be poured into each jar. To fully charge the battery, you will need to purchase 3 1 liter bottles or a five liter canister.
At the cost of these two purchases will be almost equivalent, therefore, given the unlimited shelf life of this technical fluid, it is recommended to buy a capacity of 5 liters. In this case, there will be a sufficient supply of electrolyte for topping up during battery operation.
How to charge the battery 45 Ah
If automatic chargers are used to charge the battery, then simply connect the product to the network, and the terminals to the battery. If the charger has the ability to adjust the charging current, the battery is charged according to the standard scheme. In order to qualitatively charge a current source of such a capacity, it is necessary to charge it with a current of 4.5 A for 10 hours.
Which car battery is suitable for 45 Ah?
Most of the cars on which the 45 Ah battery is installed are manufactured by Asian companies. Such batteries should be taken only for petrol subcompacts with an engine capacity of up to 1.6 liters. As a rule, the manufacturers of such batteries are: Topla, FB Super Nova, AtlasBX, Mutlu, Tab, Afa, Exide, Bosch and Varta.
Which 45 Ah battery to choose and what to look for
When choosing a battery with a capacity of 45 Ah it is necessary, first of all, to pay attention to the following technical specifications:
- Voltage. Straw 12v;
- Starting current. The higher it is, the simpler it will start in the winter and more electrical equipment can pull;
- Size and type of terminals. A battery like ASIA doesn’t mean to put in a European car, and vice versa;
- Manufacturer.The more famous the manufacturer, the more confidence in quality, but such power sources will be more expensive and more often faked.
On sale you can find a battery voltage of 24 v, which are completely unsuitable for the on-board system of cars designed for 12 v. In addition to the voltage, you must pay attention to the capacity, which should be equal to 45 a / h, as well as the size of the product and the shape of the terminals.
In addition to the standard European size, such batteries can be manufactured in Asian dimensions. The terminals can be of different diameters, and also have a different arrangement, these points should also be taken into account when choosing a battery with a capacity of 45 a / h.
By purchasing products from such well-known companies as: Varta, Bosch and Energizer, you can not worry about the quality of the batteries. Such products will last throughout the entire operation period without any complaints.
An important method is the manufacture of batteries. Technology-made batteries will last significantly longer Agm and Efb. You can also expect good performance with gel batteries.

I bought the battery of the Tyumen Battery Plant more than 2 years ago. During the entire time of using the battery, the car starts up with a half-turn, even in severe frost. Volt-ampere characteristics also did not decrease at all during this time.

I bought a Russian-made AkTech battery to replace a used Gigawatt battery. The new battery perfectly copes with the “starter” responsibilities, and when you turn on the music in the parking lot, you can not worry about excessive battery drain.
Alexander. Voronezh.
For the first time I purchased a starter battery from the Slovenian company Topla and did not regret my choice. The battery has minimal leakage of electricity, and the discharge current is so high that when the car died out at the railway crossing, it was possible to drive about 10 meters in 1st gear and the starter switched on without consequences for the battery.
