Sealed, valve-regulated and completely maintenance-free, the DC85-12 is our standard recommendation for house banks in the tropics, on boats and in off-grid homes alike \u2014 it tolerates heat, vibration and the daily charge\/discharge cycle.<\/p>\n<h3>More of the capacity you paid for<\/h3>\n<p>Fullriver rate the DC series to an 80% depth of discharge \u2014 their own published limit \u2014 where much quality AGM is held to 50%. On this 85 Ah battery that is the difference between planning around 43 Ah and planning around 68 Ah, so a smaller, lighter bank can carry the same night away from the mains. Deep cycling is still work: a bank that is fully recharged after every use will outlast one that isn\u2019t, so pair it with a multi-stage AGM charger set up with temperature compensation. In tropical heat that one setting protects your investment more than anything else you can fit.<\/p>\n<h3>Sp\u00e9cifications \u2014 DC85-12<\/h3>\n<table>\n<tr>\n<td><strong>Tension nominale<\/strong><\/td>\n<td>12V<\/td>\n<\/tr>\n<tr>\n<td><strong>Capacit\u00e9 \u00e0 20 heures<\/strong><\/td>\n<td>85 Ah<\/td>\n<\/tr>\n<tr>\n<td><strong>Capacit\u00e9 \u00e0 100 heures<\/strong><\/td>\n<td>95 Ah<\/td>\n<\/tr>\n<tr>\n<td><strong>Chimie<\/strong><\/td>\n<td>AGM, VRLA scell\u00e9e, anti-fuite<\/td>\n<\/tr>\n<tr>\n<td><strong>Poids<\/strong><\/td>\n<td>25,1 kg<\/td>\n<\/tr>\n<tr>\n<td><strong>Dimensions (L\u00d7l\u00d7H)<\/strong><\/td>\n<td>260 \u00d7 169 \u00d7 236 mm<\/td>\n<\/tr>\n<tr>\n<td><strong>Terminaux<\/strong><\/td>\n<td>M8 + poteau automatique en laiton<\/td>\n<\/tr>\n<tr>\n<td><strong>Groupe BCI<\/strong><\/td>\n<td>24<\/td>\n<\/tr>\n<\/table>\n<h3>Chargement<\/h3>\n<p>Charge with an AGM profile.
