Traction batteries are the main source of energy for moving electrical equipment - stackers, reach trucks, electric cars and electric forklifts. They are very different: there are sodium, nickel-hydrogen, lead-acid, and lithium batteries. By design, there are namazy and carapace options. The capacity is also different for everyone. And which unit should you choose in your case? That's a question!
If a simple battery installed in your car serves only to start the engine, then a traction liquid or gel battery can constantly supply current with an electric motor, which set the technique in motion. If it fails even for a second, you simply stop - or, worse, lose control. Therefore, such devices must be very reliable. Whatever happens, whatever your car collides with, they must remain in service. And traction batteries should be able to work for a long time without recharging - at least eight to ten hours.
It is clear that it is very difficult to satisfy all these conditions, but here also every user wants something special. Then give them special strength so that the unit can work even underground and on construction sites. They want something several times lighter - so that they can create a sports electric car with this device. Then, for example, they are hunting for the equipment to be able to move and work in any position, even upside down, and this did not affect its battery in any way - and in such cases, only gel batteries are suitable. And another very frequent problem is the selection of a suitable battery charger . If you buy it for yourself, it should be relatively small (or some of these "charges" take up an entire room), and the duration of the charge should be no more than ten to twelve hours - so that equipment with a battery can work every day, without interruption. No more than half of the devices on the market satisfy such conditions.
In addition, the number of discharge-charge cycles that the unit can be subjected to becomes a very important parameter. Everything here largely depends on the type of battery. So, lead-acid batteries with liquid electrolyte are able to withstand on average about 1500 such cycles. Gel batteries are designed for a smaller number - about 1200 cycles. At the same time, lithium batteries can easily withstand up to two thousand "charging" cycles. True, their cost is slightly higher.
Finally, an important requirement for traction batteries is ease of maintenance. Some devices require that they be handled with great care: they should not be exposed to liquids, sunlight, or heat. Others are quite indifferent to this. Of course, the former are much cheaper. However, it is not recommended to use them in special equipment: any excess load during operation can become the last.
