Have your Sparky power tools lost their original punch, and is your workshop efficiency suffering due to constant charging breaks? Professional Sparky BUR2 18Li HD 18V battery regeneration is a proven method to restore your devices to their factory performance, and often even improve upon it. Instead of investing in uncertain, low-quality replacements that often fail to meet advertised specifications, we offer you a service based on engineering precision and world-class components. Our company, with over 15 years of experience in the industry, guarantees that the renewal process of your battery will be carried out with meticulous attention to every technical detail.
By choosing regeneration, you are opting for a solution that is both economically rational and ecologically responsible. We utilize the original casing of your Sparky battery, which is perfectly fitted to your tools and chargers, replacing only the "heart" of the battery – the worn-out cells. By using state-of-the-art lithium-ion cells from global leaders such as Samsung, LG, or Sanyo, your battery gains a second life, offering stable operation even under extreme loads. This is an investment in quality that translates into real progress in your daily professional or DIY tasks. Our "Heavy Duty" (HD) approach ensures that your Sparky tools will once again handle the toughest drilling and driving applications with ease.
The process of Sparky BUR2 18Li HD 18V battery regeneration is a sophisticated service operation requiring specialized technical facilities. We begin by carefully opening the housing to ensure its mechanical structure remains intact. Next, we remove the old cell pack and perform a detailed verification of the BMS (Battery Management System) electronic circuit. At Lupo, safety is our priority – if the electronics show signs of damage or wear that could compromise performance, we replace them with a new, fully compatible version, ensuring proper communication between the tool and the charger.
The next crucial stage is welding the new cell pack. We use only branded, high-current Li-ion cells in the 18650 standard. The connections are made using thick pure nickel strips, which minimizes internal resistance and prevents excessive battery heating during intensive use. Every regenerated battery undergoes rigorous final testing, including capacity measurements and load tests, which we confirm by placing a service date on the casing. This gives you the peace of mind that you are receiving a product ready for the most demanding industrial challenges, fully restored to its 18V Li-ion potential.

Every Sparky BUR2 18Li HD regeneration we perform ends with the issuance of a warranty document. We are confident in our technological processes and the components used, which is why we offer support for a period of 12 to 24 months. This provides security for your budget and a guarantee that the service was performed reliably by industry professionals.
In the renewal process, we use only selected high-current cells, ensuring that your Sparky 18V battery regeneration results in maximum efficiency. These cells allow for a stable energy flow even during the heaviest tasks, such as drilling in concrete or cutting hard timber, while providing a significantly longer overall lifespan for the pack.
The key to durability is the precision of the connections. We use professional high-power welders and pure nickel, guaranteeing stable connections resistant to shock and high temperatures. As a result, energy flows without loss, and the battery does not overheat, which directly translates into the trouble-free operation of your power tools for years.
During every service, we check the condition of the safety systems. If the electronics in your Sparky BUR2 18Li are faulty, we replace them. These systems protect the cells from overcharging and deep discharge, which is crucial for maintaining high efficiency over hundreds of charging cycles. We invest in solutions that truly extend battery life.
We do not use cheap marketing gimmicks. The parameters we offer are 100% consistent with reality and confirmed by capacity tests. Thanks to branded cells, you get exactly the amount of energy you pay for, allowing you to plan your work without worrying about sudden equipment discharge. Real capacity is the foundation of the trust we build.
By using the original casing, we maintain full mechanical and electrical compatibility. Your battery after regeneration will perfectly fit all tools from the Sparky 18V series and factory chargers, including fast chargers. Solid mountings and precisely selected contacts guarantee a comfort of use identical to a new, original product.
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.
