What is an AGM battery?
ABSOLUTELY MAINTENANCE-FREE
LEAK PROOF
FIBERGLASS FLEECE
Our absolutely maintenance-free motorcycle batteries
intAct Bike-Power AGM, intAct Bike-Power SLA, intAct Bike-Power GEL, intAct Bike-Power HVT and intAct Bike-Power GEL HVT-HD are valve regulated lead-acid batteries or VRLA batteries (VRLA=Valve Regulated Lead-Acid). VRLA batteries produce much less gas …
What does absolutely maintenance-free mean?
Absolutely maintenance-free batteries are valve-regulated lead-acid batteries or VRLA batteries (VRLA = Valve Regulated Lead-Acid) that are sealed at the factory. Here, significantly less gas is produced than in wet batteries. The gas produced remains …
Why does this battery have such a good current draw?
Due to the AGM technology, this battery absorbs the current particularly well, i.e. it recharges faster than a conventional wet battery and you can charge it with a higher charging current or a more powerful charger, like the ? This characteristic comes …
What does low maintenance mean?
Low-maintenance batteries can be recognised by the removable sealing plugs on the top, the vent hose and the white or transparent housing. In these batteries, the electrolyte is in liquid form, i.e. it is not bound as GEL or in fleece. They are not sealed …
The order of disconnection and connection
The negative terminal is connected to the body, hence the name grounding. If you accidentally touch the positive terminal and the body at the same time when the negative terminal is connected, e.g. with a metallic tool, a short circuit could occur that …
Checking the battery step by step
There are many reasons for weakening or failing batteries. An important step in tracking them down is to measure the voltage with a battery tester. Here's how: 1. preparation Disconnect the battery from the vehicle, if possible remove it. Tips on how …
What waterproof brings
Ideally, batteries should be kept dry. Even slight moisture can promote leakage currents. If you've noticed condensation on your battery frequently in the past, such as with temperature fluctuations, or water can get to your battery, it's worth considering …
A coherent equation: A lot out, a lot in.
Every battery loses power over time. If it is loaded normally and is always fully charged, the capacity is slowly reduced. If it is often overloaded and insufficiently charged, the capacity is reduced much more quickly, i.e. the battery ages much faster. Ideally, …
Cleanliness pays off
To ensure proper battery function, it makes sense to keep the battery surface clean and dry. Greasy or silicone-containing dirt on the lid can hinder the flow of current. Moisture on the battery can cause a short circuit in the worst case.
What is short circuit and how do I prevent it?
Short-circuiting occurs when the two terminals or plates of a battery are accidentally connected together. This can happen if the separator between the plates is damaged by vibration, for example, or if excessive battery sludge builds up, closing the …
Why are the labels coming off my battery?
Detached labels indicate wear due to excessive temperatures. Tip: Always give your battery time to cool down before charging or use a charger that charges temperature compensated. Tip: If you operate your vehicle or device in a very hot environment, choose …
Every battery ages
With each charge/discharge process (cycle), active material is inevitably lost and the battery's performance declines. Once it has fallen to the point where it can no longer fulfil its purpose - e.g. start the vehicle, supply the consumers or drive the …
Checking the liquid level against sulphation
In a battery or accumulator, the chemical reaction between the active material of the grids and the acid generates current (electrons emitted) to supply the loads or stores current (electrons) provided by the charger or alternator. If the acid only partially …

What is a traction battery?

Traction batteries supply power to the electric motor in machines and vehicles. They are designed to be charged with a charger when not in use and then discharged when in use. Traction batteries are designed for this repetitive alternation between charging and discharging or cycling. Unlike starter batteries, they tolerate being repeatedly discharged to a depth of discharge of up to 80 % well due to the special composition and construction of the grids and separators. The cycle stability of a traction battery provides information on how often it can reach this depth of discharge under ideal circumstances before it is damaged.

Maintenance and Care

Absolutely maintenance-free batteries are valve-regulated lead-acid batteries or VRLA batteries (VRLA = Valve Regulated Lead-Acid) that are sealed at the factory. Here, significantly less gas is produced than in wet batteries. The gas produced remains in the circuit of the battery due to gas recombination. As a result, these batteries lose significantly less liquid. They do not need to be topped up, and it is not even possible to do so, as they cannot be opened again without damage.
