It's positioned for transportation, marine, and RV duty rather than the floor-cleaning-first orientation of the plain 31-AES, though the two are dimensionally close enough (12.80\" x 6.81\" x 9.43\" in Group 31 trim) that either fits the same tray.\u003c\/p\u003e\u003cp\u003eCapacity comes in at 83Ah (5-hr) \/ 115Ah (100-hr), with 177 minutes of reserve at 25 amps — lower than the standard 31-AES's 104Ah spec, reflecting a plate design tuned more for sustained heavy load than maximum amp-hour capacity. Trojan publishes separate datasheets for the Group 31 and Group 29 versions since weight and dimensions shift slightly between them (67-69 lbs depending on group size); confirm which group size the equipment tray requires before ordering.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e12V, 83Ah (5-hr rate) \/ 115Ah (100-hr rate)\u003c\/li\u003e\n\u003cli\u003eAvailable in BCI Group 31 and Group 29\u003c\/li\u003e\n\u003cli\u003eWeight: 67-69 lbs (group-size dependent)\u003c\/li\u003e\n\u003cli\u003eTerminal: stud terminal (ST)\u003c\/li\u003e\n\u003cli\u003eSealed AGM, non-spillable; 3-year warranty\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Trojan","offers":[{"title":"Default Title","offer_id":51442003378422,"sku":"TROJAN-OD-AES-31","price":499.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0606\/5291\/2886\/files\/202306-OD31-AES-29-12V-615x415-L.png?v=1786056886","url":"https:\/\/www.sweepersandfloorscrubbers.com\/products\/trojan-overdrive-aes-31-12v-agm-battery","provider":"Sweepers and Floor Scrubbers","version":"1.0","type":"link"}
