Wattstunde AGM batteries are an excellent choice because they have high cycle stability and thus a long service life even when used in a PV system. High robustness (high vibration and tilt resistance) ensures reliable operation even under harsh conditions.\u003cbr\u003e\n\u003cbr\u003e\n\u003cb\u003eBattery Construction\u003c\/b\u003e\u003cbr\u003e\nThese are valve-regulated, maintenance-free VRLA batteries. The electrolyte is bound in a glass fiber mat (AGM = Absorbent Glass Mat), so there is practically no gassing. This allows them to be used in enclosed spaces or in close proximity to people.\u003cbr\u003e\nAnother advantage of AGM technology: Due to their leak-proof design, it is possible to install the battery in any position (not just horizontally), guaranteeing maximum installation flexibility. In the event of a fault (e.g., connecting a defective charger), the integrated safety valve ensures that gas can escape.\u003c\/p\u003e\n\n\u003cp\u003e\u003cb\u003eSpecial features at a glance:\u003c\/b\u003e\u003c\/p\u003e\n\n\u003cul\u003e\n\t\u003cli\u003eMaintenance-free due to sealed construction\u003c\/li\u003e\n\t\u003cli\u003eLong service life and high cycle stability\u003c\/li\u003e\n\t\u003cli\u003eRobust, spill-proof and leak-proof\u003c\/li\u003e\n\t\u003cli\u003eEasy shipping as it is not hazardous material\u003c\/li\u003e\n\t\u003cli\u003eInstall upright\u003c\/li\u003e\n\t\u003cli\u003eWarranty period: 2 years\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003cp\u003e\u003cstrong\u003eNotes on battery capacity\u003c\/strong\u003e\u003cbr\u003e\nThe amount of energy that can be drawn from a battery heavily depends on the period over which the battery is discharged. This is represented by the so-called C-value. The number after the C describes the discharge duration in hours. The faster the battery is discharged, the smaller the usable energy amount.\u003cbr\u003e\nWhen discharged within 20 hours (C20), 33 Ah are available.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eNote\u003c\/strong\u003e\u003c\/p\u003e\n\n\u003cp\u003eAGM batteries should ideally not be discharged deeper than 50%, which corresponds to a resting voltage of approximately 12.25 V to 12.3 V (at 50% state of charge), to maximize their lifespan; deep discharge below 11.8 V should be avoided, as this significantly 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\u003cp\u003e \u003c\/p\u003e\n\n\u003cp\u003e\u003cb\u003eTechnical Data\u003c\/b\u003e\u003c\/p\u003e\n\n\u003ctable width=\"100%\"\u003e\n\t\u003ctbody\u003e\n\t\t\u003ctr\u003e\n\t\t\t\u003cth\u003eProduct Features\u003c\/th\u003e\n\t\t\t\u003cth\u003eWATTSTUNDE AGM BATTERY 33 Ah\u003c\/th\u003e\n\t\t\u003c\/tr\u003e\n\t\t\u003ctr\u003e\n\t\t\t\u003ctd\u003eCapacity\u003c\/td\u003e\n\t\t\t\u003ctd\u003e33 Ah (C20)\u003c\/td\u003e\n\t\t\u003c\/tr\u003e\n\t\t\u003ctr\u003e\n\t\t\t\u003ctd\u003emax. charging current\u003c\/td\u003e\n\t\t\t\u003ctd\u003e9.9 A\u003c\/td\u003e\n\t\t\u003c\/tr\u003e\n\t\t\u003ctr\u003e\n\t\t\t\u003ctd\u003emax. discharge current (5 sec)\u003c\/td\u003e\n\t\t\t\u003ctd\u003e330 A\u003c\/td\u003e\n\t\t\u003c\/tr\u003e\n\t\t\u003ctr\u003e\n\t\t\t\u003ctd\u003eVoltage\u003c\/td\u003e\n\t\t\t\u003ctd\u003e12 V\u003c\/td\u003e\n\t\t\u003c\/tr\u003e\n\t\t\u003ctr\u003e\n\t\t\t\u003ctd\u003eBattery technology\u003c\/td\u003e\n\t\t\t\u003ctd\u003eAGM (VRLA)\u003c\/td\u003e\n\t\t\u003c\/tr\u003e\n\t\t\u003ctr\u003e\n\t\t\t\u003ctd\u003eConnection\u003c\/td\u003e\n\t\t\t\u003ctd\u003eM6\u003c\/td\u003e\n\t\t\u003c\/tr\u003e\n\t\t\u003ctr\u003e\n\t\t\t\u003ctd\u003eWeight\u003c\/td\u003e\n\t\t\t\u003ctd\u003e10.2 kg\u003c\/td\u003e\n\t\t\u003c\/tr\u003e\n\t\t\u003ctr\u003e\n\t\t\t\u003ctd\u003eDimensions (L x W x H)\u003c\/td\u003e\n\t\t\t\u003ctd\u003e195x130x180 mm\u003c\/td\u003e\n\t\t\u003c\/tr\u003e\n\t\u003c\/tbody\u003e\n\u003c\/table\u003e","brand":"WATTSTUNDE","offers":[{"title":"Default Title","offer_id":55769359155545,"sku":"501-5033","price":83.19,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0941\/9436\/8857\/files\/wattstunde-469jpg-322543.jpg?v=1761403430","url":"https:\/\/b2bshop.wattstunde.de\/en\/products\/wattstunde%c2%ae-33-ah-akku-agm12-33-12v-vrla-agm-batterie-c20","provider":"Wattstunde | B2B Shop","version":"1.0","type":"link"}
