TYVA Refill battery recondionning
Lithium batteries represent a sustainable solution in green energy exploitation which are meant to respect the environment. But what if the battery isn’t working anymore? Does it need to be thrown away as well as all its components? Is it truly ecological? No worries, we already have the answer!



At TYVA Energie, all of our modular batteries, Moduloo 3D, Moduloo Ax, Flat & Kube incorporates the TYVA Refill patented technology. Lithium-ion cells are not welded to the module when they are produced, which means the battery can be opened even after its assembly and be changed as wanted as well. Therefore, it is possible to renew end-of-life cells without having to replace the whole battery. It is in this dynamic that TYVA Energie offers battery reconditioning for endless use among its services. This vision is consistent with the next European battery regulation that will be established in 2030. It aims to integrate lithium batteries in the circular economy, requires more eco-conception of the latter and also a deeper recycling management of its components.



 TYVA Refill technology was created by Thierry Claudel in his garage in 2013, at the same time as the TYVA Energie company. Battery reconditioning makes our products greener and more sustainable in accordance with our values. TYVA Refill doesn’t promise several life cycles and the reuse of batteries in other devices until their depletion unlike other systems available on the market. The battery repair implies there is no power loss and your products are always kept at a constant energy level. It is a freely recyclable battery solution involving a follow-up adapted to your needs.



 TYVA Refill keeps proving its efficiency since 2013. A battery reconditioning unit dedicated to this technology was even built in our new 1000 m² production site based in Annonay, in the Ardeche region, south of Lyon (France). To date, more than 12 000 end-of-life lithium batteries modules were already repaired. It represents a windfall considering it takes only 5 minutes for our technicians to replace the cells of a damaged battery!

The complete range of lithium batteries TYVA Moduloo Ax has been certified UN 38.3

UN 38.3? What is it? As you surely know, lithium batteries are classed as dangerous goods and are to be shipped with a few rules of caution. For this purpose, the United Nations defined a number of security checks called Tests UN 38.3. As security is essential to us along with providing our customers a simplified, fast and cost-effective transport; we decided to have our full Moduloo Ax range certified. Read more below!

UN 38.3 certification

In order to be carried safely by road, sea or air, lithium batteries have to pass section 38.3 of the United Nations Manual of Tests and Criteria, which includes the following controls:

T1: Altitude simulation
T2: Thermal test
T3: Vibration
T4: Shock
T5: External short circuit
T6: Impact / crush test
T7: Overcharge
T8: Forced discharge

The full range of batteries Moduloo Ax, available in several sizes and density has successfully passed all the tests and has been certified in April 2021.

Safe, fast and cost-effective – choose the Moduloo Ax range


UN 38.3 certification is a prerequisite for the transportation of lithium batteries regardless of the mode of transport. But this certification can significantly delay a project because of its cost and time required to complete all tests.

This is the reason why, at TYVA Energie, we have decided to make our full Moduloo Ax range certified. Lithium batteries from this range are compact and modular, off-the-shelf products that can meet a good number of your criteria. Here is a quick overview of their benefits:

  • Compact and modular – available in following sizes A4+, A4, A5+ and A5 and also custom,
  • Rack-mountable option,
  • High battery life and power – 245 Wh/kg,
  • Lightest batteries on the market,
  • BMS designed and manufactured by TYVA Energie’s team in France,
  • Choice of the number of cells in series and/or parallel.

Packing instructions of TYVA Energie’s lithium batteries


Issuing the UN 38.3 certificate is not the only thing to take into consideration while transporting lithium batteries. Depending on the quantity and power of the batteries, packing instructions may differ.


To this end, we have written a packing instruction guide for our different ranges of lithium batteries (Moduloo 3D, Moduloo Ax, Flat & Kube). You can find it here: https://mytyva.com/reglementation-pour-le-transport-des-batteries-lithium-ion/



Need help shipping your lithium batteries?

In 2020, 2 members of the TYVA Energie team have been trained by the certification agency AFTRAL and became IATA experts for the air transport of batteries. Don’t hesitate to contact us if you face issues while shipping your lithium batteries abroad!
