Powerstar's Sealed and Maintenance-Free Batteries: Reliable and Versatile Power Solutions

Powerstar batteries feature a unique sealed construction and sealing technique that effectively prevent any electrolyte leakage from the terminals or the battery case. This ensures safe and efficient operation of the batteries in any position, making them classified as "non-spillable" and meeting all the requirements of the International Air Transport Association.

The Absorptive Glass Mat (AGM) system employed in Powerstar batteries utilizes fine mat separators (glass fiber) that absorb sufficient electrolyte to provide the longest life and steady service. This system prevents the escape of electrolyte from the separator, which could otherwise lead to leakage.

Powerstar's innovative design incorporates a gas recombination feature that effectively controls the generation of gas and allows for the recombination of over 90% of the gas produced during normal use. This remarkable feature ensures maintenance-free operation throughout the expected floating service life of the batteries, as there is no need to check the specific gravity of the electrolyte or add water.

The combination of the sealed construction and the use of absorptive mat separators allows Powerstar batteries to be operated in any position without any loss of capacity, electrolyte, or service life. This position-free and leakage-free design makes Powerstar batteries a versatile and reliable power solution for a wide range of applications.

For the specific model, the Powerstar 6-DW-7 12V 7AH 10hr battery comes with a 3-year warranty. It has the following dimensions: 5.95 x 3.72 x 2.56 inches, and a weight of 6 lbs.

In summary, Powerstar's sealed and maintenance-free batteries offer several key features that make them a superior choice for reliable power needs. Their unique construction, gas recombination capabilities, and position-free design ensure safe, efficient, and long-lasting performance, even in demanding applications.
