Had our leisure battery from new 5 yrs ago its a numax LV25MF 90ah but it seems last year to be losing a bit of capacity so thinkng of changing. The space is tight under the passenger seat (chausson best of 10). Just been on the phone to Tanya they suggest a enduroline (their own brand). Anyone had one? Was going to go for numax again as its lasted well but that model now discontinued and the enduroline is 100AH
