In the offered batteries we use branded Lishen cells with low internal resistance and high current efficiency. These parameters ensure failure-free operation of the battery for many years.
Thanks to the use of high-current Lishen cells, as the only manufacturer we offer a quality guarantee! We are confident in our products and we are not afraid of possible warranty repairs. We have the knowledge, equipment and all the components necessary for the production and repair of the offered batteries
Pre-welded Nickel Tabs
Ready-made output tabs welded to the cell pack allow for quick and reliable connection of external contacts or battery holders. Clean, low-resistance welds ensure durability and performance. No electronics or additional tapes are included—these packs are designed specifically for NiCd and NiMH applications where only the cells and welded tabs are required. The cells have a height of 42 mm
General Battery Handling Instructions – Li-Ion and NiMh/NiCd
Before Installation
Check all cells for damage, swelling (Li-Ion), leaks (NiMH/NiCd), or corrosion.
Ensure correct polarity and clean contacts.
Do not mix different battery types or new and used cells.
⚙️ Cell Characteristics
Li-Ion: Nominal voltage ~3.7 V per cell (max 4.2 V / min 3.0 V).
NiMH/NiCd: Nominal voltage ~1.2 V per cell (full charge ~1.4 V / min ~1.0 V).
🔋 Charging
Use chargers designed specifically for the given chemistry.
Li-Ion: Always use a BMS system. Charge in a fireproof place.
NiMH/NiCd: Use a smart charger with peak detection. Avoid overcharging.
📦 Storage
Store in a cool (15–25°C), dry place away from sunlight.
Li-Ion: Store at about 3.7 V (40–60% capacity).
NiMH/NiCd: Recharge every 2–3 months.
⚠️ Safety Tips
Do not short-circuit terminals or expose batteries to fire, heat, or water.
If overheating, swelling, or leakage occurs – stop using immediately.
Do not puncture or open sealed cells.
♻️ Disposal
All batteries should be taken to recycling points.
NiCd contains cadmium – do not dispose of in mixed waste!

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.

If my previous battery was NiCd and now I have NiMh, will my old charger work properly?
Batteries that have been built on both NiCD and NiMh cells can work in the same voltage ranges. They also have the same charging current. Thus practically every NiCd charger can also operate a NiMh battery. In case of any questions or doubts about the charger or batteries, please contact our customer service department.

Guaranteed battery life
The guaranteed operating time on a given battery depends on the battery load at a given time. For example, if you use a battery for screwdriving, you will need less energy for this than, when working with a chain saw, and therefore, the operating time may be longer. Unfortunately, power tool such as chainsaws have a current flow of more than 25A, so the working time is shorter.

Can an old battery be reconditioned?
If you have a battery to regenerate, please visit our customer service department. Our company regenerates as much as 95% of batteries. However, it should be remembered that although we are able to prepare virtually every package of cells that is available on the market, the price of the service does not only include the cost of materials. The cost of our service technician's work should also be added to the price.

If the purchase battery does not match my power tool, can I return it?
We have been selling on the Internet for many years, for this reason situations like this are not new to us. Thus, in order to meet the expectations of our customers and not to cause them any problems, anyone who has bought a product from us can return it within 14 days from the date of purchase.
