Looking for a battery that won't let you down? Traction batteries are a safe bet - whether you need a reliable power source for your wheelchair, photovoltaic system or caravan. In our article, you'll learn everything you need to know: how to choose a traction battery, charge it correctly, extend its life and measure its capacity. We'll walk you through the differences between traction and starter batteries, describe battery wiring, and add tips for maximum performance. We bring you a complete overview and practical tips you'll appreciate.
Characteristics of traction batteries
Traction batteries are a specific type of battery that is characterized by high resistance to repeated discharging and charging. Unlike starter batteries, which may look identical on the surface, traction batteries are designed to withstand cycling with regular deep discharges followed by recharging. This makes them an ideal power source for devices that require long-term and stable power, such as wheelchairs or photovoltaic systems. The traction battery delivers current gradually and allows discharge up to 80%, The capacity of traction batteries is given in ampere hours (Ah) and we offer a wide range of models, for example 12V traction batteries with different capacities.
Traction battery applications
Traction batteries are used in many industries:
- Wheelchairs - they provide reliable power even in everyday use.
- Photovoltaics - they serve as a backup power source in renewable energy systems.
- Caravans and motorhomes - they provide power for appliances, lighting and other equipment.
- Golf carts and electric motors - they are crucial for powering these devices.
How to choose the right traction battery?
When choosing a traction battery, it is important to consider:
- Capacity (Ah): Higher capacity means more power for your equipment. It is recommended to choose a battery with a reserve. If you need a 100Ah battery, consider a model with a capacity of at least 120Ah or more. This will ensure that even with deep discharges, the battery will operate efficiently and its life will be extended.
- Number of cycles: when choosing a traction battery, it is crucial to consider how often the battery will be cycled, i.e. how many times it will be discharged and charged. Different types of batteries have different lifetimes, which depend on the number of cycles the battery can handle before its capacity drops. A higher number of cycles means a longer life and greater reliability of the battery.
- Voltage (V): when selecting a traction battery, it is crucial to choose the right voltage to match the requirements of your application. For a wheelchair, the battery must have a voltage that will provide sufficient motor performance. Too low a voltage can impair performance, while too high can damage the equipment. Proper voltage ensures optimum performance and long battery life.
- Size and Weight: Consider the space options and limitations for battery installation.
Traction battery charger
The use of traction battery chargers is essential for proper traction battery operation. These chargers allow precise control of the charging process and minimize the risk of overcharging.
Traction battery lifetime
The life of a traction battery depends on the depth of discharge. If you regularly discharge the battery to only 40%, you will achieve a longer life than if you discharge it to 80%. In addition, it is important to take regular capacity and voltage measurements.
Measurement of traction battery capacity and voltage
To determine whether your traction battery has sufficient capacity to provide the required energy, it is essential to take measurements. A load capacity tester is used to accurately determine the condition and capacity. While the battery voltage may be fine, insufficient capacity means that the battery will not be able to efficiently deliver power as required.
To measure traction battery voltage, we recommend using a multimeter or battery tester to ensure your battery voltage is properly checked. If you are storing your battery for a long period of time, we recommend checking its voltage regularly at least once every three months to prevent damage or loss of capacity.
Series and parallel battery connections
Traction batteries can be wired to increase power or capacity:
-
- Series: To increase the voltage, for example, make two 12V batteries 24V by connecting the positive terminal of the first battery to the negative terminal of the second battery.
- Parallel: To increase the capacity, for example, by connecting two 100Ah batteries, you get 200Ah by connecting the positive terminal of the first battery to the positive terminal of the second battery. This doubles the capacity and does not change the voltage.
