Car enthusiasts, like professional drivers, are well aware that the main and very important component of any car is the battery. It depends on how powerful it is sometimes that you can start your car. Today we look at the technical characteristics of 40 Ah batteries and find out how productive they are.

How much does a battery weigh 40 a / h
Experienced drivers know that the weight of a car battery sometimes indicates how well it is made. This indicator depends on three parameters:
- weight of the plastic case (monoblock);
- the amount of lead used;
- volume of electrolyte.
It is believed that the more lead - the better the car battery will work. So any car battery with a capacity of 40 a / h on average should weigh 10.6 kg, and if you pour out the electrolyte then 8.8 kg. However, due to unscrupulous manufacturers, the weight is sometimes significantly different. This happens with insufficient use of lead, a low level of electrolyte.
For some manufacturers, the weight differs from the general parameters initially, for example, the Austrian manufacturer Banner offers batteries weighing 9.5 kg and even 11.2 kg, and the Korean Bost - 10.5 kg.
Battery Dimensions and Terminal Options
To ensure that the battery installation does not cause problems, the battery must have suitable dimensions for the engine compartment. This indicator depends on the manufacturer and ranges from:
- It is long: Strictly 187 mm;
- Width: 124-128 mm;
- Height: 220-227 mm;
40 Ah car batteries are available exclusively for Asian cars (Japanese, Korean, etc.), so they all come with ASIA terminals - these are thin terminals towering above the battery case.
How much electrolyte is in the battery 40 a / h
Considering that the average weight of a starter battery with 6 cans (6 st) is about 10.6 kg, and without an electrolyte 8.8 kg, it turns out that the weight of the electrolyte itself is about 1.8 kg. For some manufacturers, the weight of the electrolyte may be slightly more up to 2 kg or slightly less.
If this indicator is significantly lower, then the manufacturer has saved and neglected existing standards. For checking electrolyte level just lower the glass tube and touch its plates. The electrolyte should cover 1-1.5 cm of the tube.
How to charge the battery 40 a / h
The charge current of the car battery 40 a / h should be constant. Proper charging involves using a maximum current of 10% of the nominal battery capacity. It turns out that for a given capacity of 40 (a / h), a current of not more than 4 amperes can be set.
Choosing one of the known methods of charging, and taking into account the features of the model of the charger, the 12-volt battery charges for at least 10 hours. The charge current is monitored and decreases every 2-3 hours, as the indicator of battery voltage increases. Long-term charging, which can reach up to two days, implies the use of a current of less than 10% of the nominal capacity.
Fast charging of a 12 V battery, which can take 5 hours under high current, but often this method cannot be used - the device, in particular lead plates, will quickly wear out.
For which cars is the battery 40 a / h suitable
For cars made in Asia. The battery capacity is not very large, so it is suitable for very small compact cars, only with a gasoline engine and a volume of up to 1 liter.
Which battery to choose and what to look for
When buying a battery for a car, owners should first of all navigate by the brand of the manufacturer, as the most popular are the models produced by the company: Bosch, Feon,Akom, Westa, Alaska, Varta, Totachi, Tyumen battery.
When choosing a battery of 40 a / h, you should immediately be guided by the fact that such a battery gives an inrush current of 330 to 380 A (depending on the manufacturer), it is suitable for small compact cars, and not for large cars. Therefore, before choosing something - look under the hood of your car and see how much power the previous battery had.

Once, my battery fell into disrepair right on the road, stood the Varta A15 Blue Dynamic Asia 40Ah, in general, it worked for no more than two years. There was not much money and I had to take “what was” at the nearest store. Advised ALASKA CMF 40 R 42B19 silver +, bought. I go for almost a year, I have Daewoo Matiz, no problem. Once even the light did not turn off - nothing started!

The first car was equipped with a Totachi CMF 40 a / h 42B19 RS battery, while the new one started normally. About the second year, problems began - it quickly sat down, took a bad charge, slowly charged for a long time, generally weak. Immediately threw it, bought a more powerful one.
Veronika Sergeevna, 37 years old, Omsk
I have Akom 40, I would say - a kind of inexpensive version of the battery, when there is no way to take something better. Perfectly justifies its value. If you follow him - boldly hold out until 3-4 years. True weak charge often have to recharge.
