## Description

**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.

### **Needs venting?**

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