Question: A forestry feller buncher operating in British Columbia requires a battery system capable of delivering 1,800 CCA (Cold Cranking Amps) at -18°C. The technician specifies two 12V batteries connected in series. If each battery has a CCA rating of 900A, what is the combined CCA of this series-connected battery bank?
Answer options: ✅ 900 CCA
- 1,800 CCA
- 450 CCA
- 3,600 CCA
