BAE Batterien GmbH (BAE), located in Berlin, is a medium-sized company with a long tradition in manufacturing industrial lead-acid batteries. Since more than 110 years BAE supplies reliable energy to the world. While doing so BAE sets high quality standards for its products, which are all certified to DIN EN ISO 9001, 14001 and 50001. Besides BAE is certified according to OHSAS 18001. The core business of BAE is the production of stationary batteries, especially wherever electricity needs to flow uninterrupted like in the emergency power supply for data centers, hospitals, electrical power supply facilities and telecommunication infrastructures. More over BAE produces batteries for motive power and railway applications. Since many years BAE also operates in the market for renewable energy. BAE provides solutions for a reliable and environmental-friendly electrical power supply. BAE solar batteries are used in hybrid applications as well as in stand-alone photovoltaic systems, which include a very wide range of sizes and application fields. So BAE solar batteries have been proven in industrial energy systems even under extreme conditions as well as in private households, e.g. to increase the content of self consumed solar PV energy. BAE offers low maintenance VLA batteries with liquid electrolyte as well as maintenance free batteries in VRLA-GEL technology. Due to the high cyclic requirements batteries with positive tubular plates are used only. Moreover BAE is able to supply tailor-made solutions. BAE solar batteries reflect outstanding quality by: long cycle life approved acc. to IEC 61427, fully insulated battery design to ensure touch protection, very good recharge behaviour, excellent deep discharge capability, perfect reliability due to absolute tight pole bushing, external intercell connector design for all solar block batteries and easy access for measurements of e.g. voltage via service ring and/or pole screw.
