A motorhome parked on the drive slowly loses charge to its alarm and tracker. Write the fitting date on each battery in the bank. Leaving a caravan battery flat all winter often ruins it.
Buying the Fullriver FT410 online
Sailing yachts, motor cruisers and campervans all turn up among the users of the Fullriver FT410. Holding 28Ah, it keeps a fridge and lights going through a quiet night at anchor. Comparing batteries online side by side helps balance capacity, weight and room in the locker.

Answers before you buy
How big and heavy is this Fullriver battery?
At 165 × 176 × 144 mm, measure the tray or compartment carefully. Plan the lift too: 10.4 kg is heavier than it looks.
What do 28Ah and 410A mean for this battery?
The cranking figure is 410A, measured to the EN standard, and the capacity is 28Ah. If your engine is large or you live somewhere cold, choose the higher end of what your vehicle allows.
Can I connect several of these in series or parallel?
Yes, 12V with 28Ah. Two in series would give double the voltage.
Quick compatibility checklist
- ✓ Terminal check: M6 + TP26 (SAE). Spade widths and post diameters vary, so match the type exactly.
- ✓ A different chemistry from AGM may need system changes.
- ✓ Measure the space available: the case takes up 165 × 176 × 144 mm, and a few millimetres too many can stop the hold-down from closing.

The AGM technology explained
Compression inside the case is part of what makes glass-mat batteries so sturdy. Ambulances and police cars use AGM for their heavy electrical loads. Recharge an AGM battery promptly after deep use.
