Choose a battery for your devices

Enter the total power of your connected devices and how long they run per day — we'll work out the capacity you need in Ah and show matching Toyama models.

Total device power 60W
Daily runtime 4 h

Recommended capacity
14 Ah
Demand 240 Wh ÷ 12V, with margin to 50% discharge (AGM/Gel)

Matching models from the Toyama range

The result is an indicative nominal capacity with margin for a safe depth of discharge — AGM/gel batteries shouldn't be discharged below 50% of capacity, while LiFePO4 handles discharge to 80–90% well. Details and example use cases (campers, solar) are covered in the Guide.
