Stable power supply in all conditions The Extralink AGM 12V 40Ah battery is an efficient energy source that makes your devices work efficiently even in demanding environments. With a cyclic life of up to 600 times, the product offers long-term use without the need for frequent cell replacement, which contributes to greater savings. Standard 12V voltage and optimal capacity help maintain operational continuity wherever mobility and readiness for action are important. Safety-friendly design The glass mat technology used makes the structure completely tight and leak-proof, which eliminates the risk of contact with the electrolyte. The device offers resistance to vibrations and extreme temperatures, thanks to which it remains operational in more difficult outdoor conditions without the need to ventilate the rooms. The maintenance-free nature of operation means that the user does not have to remember to refill fluids, enjoying constant performance for years. Versatility in everyday tasks This universal energy storage helps power a wide range of devices, from alarm and monitoring systems to lawn mowers and wheelchairs. It is perfect for camping or fishing trips, offering access to electricity where there is no power grid. The ability to work in any position facilitates installation in compact housings of UPS power supplies or cash registers. Stability in buffer mode In buffer mode, the battery remains constantly connected to the charging source, which makes it always ready for immediate operation in the event of a network failure. This solution helps protect the continuity of operation of emergency lighting systems and cash registers, preventing the loss of important data. The lack of risk of overcharging protects cells and extends their service life in voltage maintenance systems. Multi-level cell protection Integrated protection mechanisms ensure that the device is not damaged during deep discharge or overload. Special thermal protection prevents the housing from overheating, which is crucial during intensive use in closed toy housings. The tight VRLA housing limits corrosion in the work environment, which positively affects the life of the connected cables and contacts. Mobility and compact size The low weight of only 12.6 kg and small dimensions make the product extremely handy and easy to transport during trips. It helps power mobile devices in campers, taking up minimal space in technical storage compartments. The solid housing with dimensions of 197 mm by 176 mm allows installation in places with limited space without loss of energy efficiency.
