Filling of AGM batteries

​

The combination of vacuum filling and high filling accuracy makes the filling process complicated for these batteries.

​

The vacuum is created by powerful pumps with a capacity down to -99.5% relative pressure.

The actual vacuum used will be optimized for each battery type.

​

To achieve the high filling accuracy either Coriolis mass flow meters or Electromagnetic flow meters are used.

The former measures the mass with a accuracy down to ± 3g and the latter the volume with a accuracy down to ±0.5%.                

For really small volumes < 100ml/cell (i.e. Motor cycle batteries) we use special made syringepumps.                                                       The mass/volume is separately measured for each cell.

​

As options to the AGM filling machine we offer acid cooling, battery weighing, gel mixing and product identification system.

Källström has a long experience in building machines for these demanding batteries and we offer state-of-the-art machines

based on this experience.

​

We offer everything from small fillers for the lab to fully automatic machines.

Machines for monoblock/block batteries The acid Filler SF4-8 for these batteries is our mostly sold filler AGM filling machine. It comes in single, double or triple headed versions either with fixed or movable filling heads.   Read More

Machines for small batteries ​ For small filling volumes < 100ml/cell our standard flow sensors are not accurate enough and therefore we have developed syringe pumps for this purpose. Since the batteries are small it is also possible to fill many batteries at the same time. ​ Read More  Specification-Acid-Filler-SF4-8-with-syringe-pumps ​
