Wattstunde's AGM batteries are an excellent choice because they offer high cycle stability, ensuring a long service life even when used in PV systems. Their high robustness (high resistance to vibration and tilting) guarantees reliable operation even under harsh conditions.\u003cbr\u003e\n\u003cbr\u003e\n \u003cb\u003eBattery construction\u003c\/b\u003e\u003cbr\u003e\n These are valve-regulated and maintenance-free VRLA batteries. The electrolyte is bound in a glass fiber mat (AGM = Absorbent Glass Mat), so that virtually no gassing occurs. This allows for use even in enclosed spaces or in close proximity to people.\u003cbr\u003e \nAnother advantage of AGM technology: Its leak-proof design allows the battery to be installed in any position (not just horizontally), thus guaranteeing maximum installation flexibility. In the event of a fault (for example, connecting a defective charger), the integrated safety valve ensures that gas can escape.\u003c\/p\u003e\n\n\n\u003cp\u003e \u003cb\u003eKey features at a glance:\u003c\/b\u003e\u003c\/p\u003e\n\n\n\u003cul\u003e\n\n\u003cli\u003e Maintenance-free due to sealed design\u003c\/li\u003e\n\n\u003cli\u003e Long service life and high cycle stability\u003c\/li\u003e\n\n\u003cli\u003e Robust, spill-proof and leak-proof\u003c\/li\u003e\n\n\u003cli\u003e Easy shipping because it's not hazardous material\u003c\/li\u003e\n\n\u003cli\u003e Install standing upright\u003c\/li\u003e\n\n\u003cli\u003e Warranty period: 2 years\u003c\/li\u003e\n\n\n\u003c\/ul\u003e\n\n\n\u003cp\u003e \u003cstrong\u003eInformation on battery capacity\u003c\/strong\u003e\u003cbr\u003e\n The amount of energy that can be drawn from a battery depends heavily on the discharge time. This is represented by the so-called C-rating. The number following the C indicates the discharge time in hours. The faster the battery discharges, the smaller the usable energy output.\u003cbr\u003e \nWith a discharge within 20 hours (C20), 33 Ah are available.\u003c\/p\u003e\n\n\n\u003cp\u003e \u003cstrong\u003eNotice\u003c\/strong\u003e\u003c\/p\u003e\n\n\n\u003cp\u003e AGM batteries should ideally not be discharged below 50%, which corresponds to a resting voltage of approximately 12.25 V to 12.3 V (at 50% charge), to maximize their lifespan; deep discharge below 11.8 V should be avoided as this greatly reduces performance and cycle life, although some special AGM types (semi-traction) can go down to 70%, 50% is the standard for most applications.\u003c\/p\u003e\n\n\n\u003cp\u003e\u003c\/p\u003e\n\n\n\u003cp\u003e \u003cb\u003eTechnical data\u003c\/b\u003e\u003c\/p\u003e\n\n\n\u003ctable width=\"100%\"\u003e\n\n\u003ctbody\u003e\n\n\u003ctr\u003e\n\n\u003cth\u003e Product features\u003c\/th\u003e\n\n\u003cth\u003e WATTSTOUR AGM BATTERY 33 Ah\u003c\/th\u003e\n\n\n\u003c\/tr\u003e\n\n\u003ctr\u003e\n\n\u003ctd\u003e capacity\u003c\/td\u003e\n\n\u003ctd\u003e 33 Ah (C20)\u003c\/td\u003e\n\n\n\u003c\/tr\u003e\n\n\u003ctr\u003e\n\n\u003ctd\u003e max. charging current\u003c\/td\u003e\n\n\u003ctd\u003e 9.9 A\u003c\/td\u003e\n\n\n\u003c\/tr\u003e\n\n\u003ctr\u003e\n\n\u003ctd\u003e max. discharge current (5 sec)\u003c\/td\u003e\n\n\u003ctd\u003e 330 A\u003c\/td\u003e\n\n\n\u003c\/tr\u003e\n\n\u003ctr\u003e\n\n\u003ctd\u003e Tension\u003c\/td\u003e\n\n\u003ctd\u003e 12 V\u003c\/td\u003e\n\n\n\u003c\/tr\u003e\n\n\u003ctr\u003e\n\n\u003ctd\u003e Battery technology\u003c\/td\u003e\n\n\u003ctd\u003e AGM (VRLA)\u003c\/td\u003e\n\n\n\u003c\/tr\u003e\n\n\u003ctr\u003e\n\n\u003ctd\u003e Connection\u003c\/td\u003e\n\n\u003ctd\u003e M6\u003c\/td\u003e\n\n\n\u003c\/tr\u003e\n\n\u003ctr\u003e\n\n\u003ctd\u003e Weight\u003c\/td\u003e\n\n\u003ctd\u003e 10.2 kg\u003c\/td\u003e\n\n\n\u003c\/tr\u003e\n\n\u003ctr\u003e\n\n\u003ctd\u003e Dimensions (L x W x H)\u003c\/td\u003e\n\n\u003ctd\u003e 195x130x180 mm\u003c\/td\u003e\n\n\n\u003c\/tr\u003e\n\n\n\u003c\/tbody\u003e\n\n\n\u003c\/table\u003e\n\n","brand":"WATTSTUNDE","offers":[{"title":"Incl. 19% VAT","offer_id":55914740711799,"sku":"501-5033","price":79.19,"currency_code":"EUR","in_stock":true},{"title":"Including 0% VAT according to Section 12 Paragraph 3 UStG.","offer_id":55914740744567,"sku":"501-5033","price":66.55,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0922\/6770\/8791\/files\/wattstunde-469jpg-327904.jpg?v=1761420902","url":"https:\/\/solorkontor.shop\/en\/products\/wattstunde%c2%ae-33-ah-akku-agm12-33-12v-vrla-agm-batterie-c20","provider":"Solarkontor","version":"1.0","type":"link"}
