Enabling people all over the world to communicate hassle-free.

In a world where everything is connected, connection must never be lost

In a world where everything is connected, connection must never be lost. At the same time, the world needs to shift from fossil fuels to clean green energy. This is where Polarium comes in.

The telecom network of the future needs to be smarter, greener, and more cost-effective. The roll-out of 5G will add millions of new nodes to already rapidly expanding networks. With 5G, more and more critical systems and applications will depend on always-on connectivity. Simply put, the connected world needs great power backup.

Telecom battery backup has long been a costly and challenging issue. Conventional batteries need to be changed frequently, diesel is costly and pollutes the environment, and actual backup time and life expectancy of batteries is uncertain due to lack of intelligence. Not anymore. Our products are small, light and maintenance-free. Polarium’s telecom battery backup solutions are sustainable, due to their extraordinarily long lifetime, fully recyclable materials, and the fact that they can be remotely controlled and monitored.

Today, telecom battery backups are mostly seen as an insurance policy, but we are striving to transform them into revenue generators by optimizing lithium batteries for smarter energy use. Our solutions let you focus on your core business and save money – helping to save our planet at the same time.

Our Green Product Range

Green is our product range consisting of excellent energy storage solutions with low carbon footprint. The products are built on lithium-ion battery cells whose manufacturing is powered by 100 percent renewable energy. The range is enabled by a long-term partnership with the Swedish battery developer Northvolt.

Our Technology

We have vast experience and expert know-how in telecom. Our telecom battery back-up solutions built on lithium batteries are of superior quality and are implemented all across the globe, even in the toughest environments.

We enable hassle-free communication and sustainable technology for the energy demanding telecom business. The implementation of 5G will increase the need for energy further, and we want it to be safe and sustainable.

  • Safe

    Our first priority is, and will always be, safety. All our products are designed with your safety in mind - thoroughly verified and certified for safe operation. We have a completely redundant safety system in the BMS, including electronically controlled circuit breakers, thorough control in the design and manufacturing of every system component to ensure safe operation. We also have advanced solutions for propagation prevention. The battery is protected during transportation, installation and use, even in the toughest conditions. Polarium is safe every step of the way.

  • Simple

    In a few simple steps you are good to go. Advanced technology made super easy to use, allowing you control without obstacles. Easy installation and zero maintenance – just connect the cables and turn on power. Our products are plug-and-play compatible with existing power systems thanks to our patented charge control function. Configuration and testing are automatic. Polarium’s solutions are designed to support a wide range of deployment configurations and integration partners, with both low and high voltage battery systems.

  • Strong

    We have installations in more than 70 countries, from the equator to the Arctic. Our products are strong, robust and of superior quality with a guarantee to provide a long-lasting life. They just keep working, even in the most extreme conditions and environments. The robust design includes optional ingress protection of the electronics. A wide range of lithium cell chemistries targeting different site conditions make our offering stronger than any other alternative in the market.

  • Smart

    Thanks to the embedded intelligence of the lithium batteries, you will always know the state of charge (available capacity in real time) and the state of health (available life for optimal planning and usage). With a remote management system, the lithium power backup solution is maintenance free and you are in full control. You can also manage your on-site climate control system based on the internal temperature of the lithium battery or you can choose to shut down non-prioritized loads. All in all, with the smart information already embedded in the lithium battery you can gain control, plan better, save cost, and reduce the environmental impact.

  • Secure

    You can feel secure, knowing that your Polarium solution is protected. Lead-acid batteries are stolen in many parts of the world due to scrap metal value, private usage, or re-sale back into the market. With Polarium’s lithium battery modules, the first two reasons for theft are eliminated. To address the last issue, we have developed multiple anti-theft features for our batteries, which completely prevents discharge of the battery module if removed from the installation. In addition, the batteries are prepared for our optional GPS tracker and marking alternatives, for recovery in case of theft.

  • Sustainable

    Polarium’s lithium batteries are fully recyclable and meet all the RoHS, WEEE and REACH requirements. Also, the energy turn-around losses are only a few percentages, which is superior compared to other lithium batteries (normally up to 5%) and lead-acid (normally up to 30%). Every solution and product are made to have an extraordinary long lifetime and designed to stand the test of time. Our low carbon manufacturing and installation, efficient operation and the fact that our products are recyclable – all contributes to a circular business model.
