Trojan 31-AES 12V AGM Deep-Cycle Battery
- Brand:
- Trojan
- Part no:
- 31-AES
A valve-regulated AGM battery that Trojan makes in Groups 29 and 31; this is the Group 31, which Trojan gives as 12.80 x 6.81 in and 69 lb, 9.37 in high in its group table and 9.43 in on its data sheet. Trojan's data sheet gives 104 Ah at the 20-hour rate (83 Ah at 5 hours), 540 CCA at 0°F and 178 minutes of reserve capacity, and charger settings at 77°F of 14.40 V absorption and 13.50 V float. Trojan says it can be installed horizontally or vertically and that no watering is required, and backs it with a 3-year warranty.
Our take
This suits a house bank or a trolling-motor and electronics bank where you want a sealed battery you can lay on its side, and the maker rates it 104 Ah at the 20-hour rate. At 69 lb it is heavy, so measure the battery box and plan the lift before you buy.
