Summary: What you are looking at: the Q-Battery 12SEM-135, a 135Ah 12V battery for boats and motorhomes. Terminals are of the A-Pole type, so make sure your clamps suit them.
Three nights at anchor with the fridge running show quickly what a battery bank can really do. Check the mains charger setting each spring. Lights that fade by midnight are a sign the domestic bank has lost capacity.
Built for life on board boats and motorhomes, the Q-Battery 12SEM-135 keeps lights and pumps going. Battery boxes on boats often leave little room, so dimensions matter. Batteries online for boats and motorhomes are simplest to choose by the code on the old one.
135Ah sits in the comfortable middle for boats and motorhomes.
Check two things together: size (349 × 175 × 290 mm) and orientation (positive on the right-hand side). Both must match.
Store it fully charged, away from heat and frost, and give it a refresh charge before installation.
Keep the code 12SEM-135 handy for next time: it makes reordering at baterias.online quick. Note the fitting date somewhere you will find it again.
A classic lead-acid battery has lead plates sitting in liquid sulphuric acid. Conventional batteries deliver high current at a modest price. A fully charged battery resists freezing far better than a flat one.
