We are convinced of the excellent quality of our products and we are not afraid of possible warranty repairs. We have the knowledge, equipment and all necessary components for the production and repair of the offered batteries


Each remanufactured battery in our company undergoes a performance and capacity test. Together with the regenerated battery, we will send you a discharge diagram along with the battery capacity, initial and final voltage. Therefore, you are guaranteed that the battery you receive has the declared capacity.
Did you know that half of electronics damage is caused by external factors? Genuine Hilti electronics are coated with a thick layer of resin that protects the electronics from moisture and dust. Therefore, its lifespan is longer.


The offered battery is a regenerated product, therefore the housings may show signs of use - they may have abrasions and scratches. The above does not affect the correct operation, because other elements of the battery are replaced with new ones. The original housing is a guarantee of durability and proper fit to the device.

Specific References
1) The accurate working temperature
Batteries suffer very badly at extreme temperatures. If you want to extend the life of your battery, you should avoid overloading it too much. If your battery works for a very long time, that's why it is probably very hot. It is wise to pull it out of the device and wait 10-15 minutes until it cools down.
2) Battery overcharge
If you want your batteries to have a very long life, you should also avoid their deep discharge. If during daily work on the battery you see a fairly large decrease in the efficiency of the device powered by the battery, you should stop its work as soon as possible and connect the battery to the charger.
3) Battery rest
You must also remember that the discharged battery for proper operation needs about 5 minutes of "free charging" before connecting to ”normal” charging. During "free charging" our battery temperature will drop significantly which will obviously have a very beneficial effect during subsequent charging.
4) Appropriate storage of the battery
The life of batteries is also greatly influenced by their proper storage. If you are not going to use the battery in the near future, it is worth charging it for the level 60-70%. Charged battery should be put in a safe place with temperature above zero.
5) Battery formatting
If you have batteries based on popular NiCd cells, you should also remember that it is possible that the so-called "memory effect" may occur. Batteries with NiCd cells should be discharged at least once every three cycles, and then charged to 100% level. Through these actions you will keep the maximum capacity of the battery.
