Better than Deep Cycle AGM?

No in performance — AGM is maintenance-free and lasts 1-2 years longer. But semi-traction costs 40-50% less.

Yes, releases oxygen and hydrogen during charge. Install in a vented external locker.

SEMITRACTION BATTERY

Semi-traction batteries: 6V/12V flooded lead-acid monoblocs with plates thicker than SLI but thinner than industrial traction. 100-260 Ah, 600-900 cycles at 50% DoD.

A mid-point between industrial traction and deep-cycle AGM — ideal for large motorhome, fishing boat house bank and basic intensive solar at a contained price.

Semi-traction — the link between cranking and traction

Semi-traction is flooded lead-acid (open-cell) with reinforced plates and Pb-Sb alloy. Tolerates regular deep discharge (50-60%) without damage, 600-900 cycles. Needs distilled water top-up every 3-6 months but costs half an equivalent AGM.

Code	V	Ah	Application
SC100	12	100	Light motorhome
SC150	12	150	Mid motorhome
SC200	12	200	Big RV, marine house
SC260	12	260	Small residential off-grid

Applications

Intensive-use motorhome with optional cranking
Fishing boat (house bank)
Basic residential off-grid solar
Market cart, food-truck

Better than Deep Cycle AGM?: No in performance — AGM is maintenance-free and lasts 1-2 years longer. But semi-traction costs 40-50% less.
