Frequently Asked Questions
Can the Deka 8A31DTM power accessories when the engine is off?
A: Yes. Its dual-purpose design makes it a good option for applications where the battery may need to power electronics or accessories while the engine isn’t running, in addition to providing starting power.
Can the Deka 8A31DTM replace another Group 31 battery?
A: Potentially, but the Group 31 size alone doesn’t guarantee compatibility. You should also compare the voltage, dimensions, terminal configuration, and required starting power or deep-cycle performance of the battery being replaced.
How should I store my Deka 8A31DTM AGM battery when not in use?
A: Before storing it, make sure the battery and terminals are clean, and the battery is fully charged. Store it in a cool, dry location and periodically check its state of charge so it does not remain discharged for a long period of time.
What does “dual terminal” mean on the Deka 8A31DTM battery?
A: This battery has both SAE posts and threaded stud terminals, giving you more flexibility when connecting battery cables and accessories. This can be especially useful in marine and RV applications where multiple electrical connections may be needed.
What should I do with my old Group 31 AGM battery?
A: Lead-acid batteries should always be recycled properly, never thrown in a household trash can. Many battery retailers, automotive stores, and recycling facilities accept used batteries for proper recycling. If you bought your battery from us, you can send it back, and we will take care of it for you.
