Common questions about the Fullriver DC90-12
Does my charger suit the technology of this battery?
Look at the sticker on the battery you have now. If it also says AGM, this is a like-for-like choice. If not, check your vehicle or system can handle the change.
What connector type is fitted to this battery?
With M6 terminals on this model, cables that already fit that type need no adapter.
Are there other sizes in the same series?
Yes: it is part of DC Series. Other members of that family use the same technology.
Is this the right replacement for my current battery?
Read the part number on your existing battery and look up the original fitment in the manual. If either points to DC90-12, or the figures agree, it will work.
Quick compatibility checklist
- ✓ With M6 terminals, some installations need a different clamp or adapter. Check before fitting.
- ✓ A different chemistry from AGM may need system changes.
- ✓ Size check: 307 × 169 × 215 mm. A battery even slightly taller than the original can touch the bonnet or the seat base.

About the technology: AGM
Oxygen formed at one plate travels through the mat and recombines at the other. Motorcycles benefit from glass-mat batteries because they tolerate lean angles and vibration. Check the charging voltage limit printed on an AGM label.
