The next generation of batteries

Advantages

  • %IMG_ALT% %IMG_ALT%
    More power for the toughest applications

    The TBX batteries with tabless cell technology give your cordless tools extra power so that you can tackle the toughest applications with ease. Due to the lower internal resistance of the battery cells, the batteries can deliver more energy, resulting in greater efficiency and productivity. With the Tabless batteries, you can equip your cordless tool portfolio with additional power that you can always rely on.
  • %IMG_ALT% %IMG_ALT%
    Longer running times with shorter charging times

    Do you want to work for longer and, above all, without interruption - whether it's sawing, sanding or dust extracting? Tabless technology makes both possible: it extends the running times of the tools and shortens the charging times of the batteries. This means you are ready for use again more quickly. And because the batteries don't need to cool down as much before charging, you can charge the empty batteries directly and use the full ones to continue working.

  • %IMG_ALT% %IMG_ALT%
    Longer service life and resistance to extreme temperatures

    The tabless technology extends the service life of the batteries. Thanks to the lower heat development and optimised energy flow, components are protected and last longer. Another advantage: the tabless batteries are more reliable in extreme temperature fluctuations - even after a cold winter's night in the vehicle, the tools are immediately ready for use. And so that you really don't have to worry about anything: Festool's 3-year guarantee also applies to the tabless batteries.

What is the difference between tabless and Li-HighPower batteries? In short: What is tabless?

The familiar Li-HighPower batteries use classic round cells that only have one tab per pole. The current accumulates there and this leads to a high internal resistance and thus to increased heat generation. Heat in the Battery pack affects the running time and service life of the battery: It simply switches off if it overheats during use (shortened runtime, although the Battery pack would actually still have remaining capacity). br]
Tabless round cells, on the other hand, have numerous tabs: the current can flow to the terminal via several paths, which significantly reduces internal resistance and heat generation. Tabless: You can compare it to a multi-lane motorway on which traffic flows better and there are no traffic jams.

What are the advantages of tabless cells?

The design of the tabless cells offers numerous advantages

Tabless Battery packs

  • provides a performance boost,
  • ensures longer running times, slower decline with time than batteries with classic cells,
  • offers better performance at very high and very low outside temperatures and faster charging than conventional Battery packs.
What does "TBX" stand for?

Tabless
Battery
Extra Power

This abbreviation will also be found on the battery packs in order to identify them visually and to be able to distinguish them quickly from the previous Li-HighPower battery packs.

Which 18V cordless tools from Festool offer the benefits of tabless?

The new tabless cell technology has positive effects on all 18V cordless tools: It is a "power upgrade" for the entire Festool 18V cordless tool portfolio.

Which Battery packs will be converted to the new tabless technology?

We are converting the previous 4.0 Ah and 8.0 Ah Li-HighPower battery packs to tabless technology. These will then be available as TBX 4 and TBX 8 Battery packs. The new TBX battery packs completely replace the previous Li-HighPower battery packs and are not an addition to the battery pack portfolio.

Will the tabless Battery packs cost more than the previous ones?

No, the Tabless Battery packs will not cost more than their predecessors. We pass on the technological advantage of the Tabless Battery packs to our customers at no extra charge.

Do the tabless batteries need special chargers?

No. All 18V chargers can still be used. The fastest charging times are achieved with the SCA 16 Charger.

Will the introduction of tabless Battery packs change the interfaces on the products or other known product features?

No! The interface of the Battery packs does not change. The TBX battery packs can be used with all Festool 18V cordless tools, just like the previous Li-HighPower battery packs with 4.0 Ah and 8.0 Ah. Other features such as the Bluetooth functionality or the rubber coating on the battery pack are also retained.

The biggest change inside the battery pack is the use of tabless cells. On the outside, the tabless battery packs will be given a new label so that they can be quickly distinguished from the previous Li-HighPower battery packs.

Why aren't the 5.0 Ah Battery packs also being converted to tabless?

This is due to the cell dimensions used in each case:

4.0 and 8.0 Ah Battery packs -> 21700 cells
3.0 and 5.0 Ah Battery packs -> 18650 cells

In the power tool range, larger volumes run on the 21700 cells. Accordingly, innovations are also introduced earlier. For this reason, we have initially equipped the 4.0 Ah and 8.0 Ah Battery packs with the new cell technology.

So why should I still buy the "older" or "weaker" 5.0 Ah Battery packs?

With the introduction of the tabless battery packs, we have streamlined the battery pack portfolio so that we offer exactly the battery packs that are ideal for the individual tools and the respective applications. We recommend the 5.0 Ah Battery pack for machines that require a good balance between performance and ergonomics as well as runtime requirements. It provides sufficient power for these tools (in this case more than the TBX 4 Battery pack), but is also lighter than the TBX 8 Battery pack, making work a little easier.
