From 7 to 30 Ah, replacing several YTX/YTZ references with a single universal battery. Designed for workshops and riders who want to simplify motorcycle battery stock: instead of holding several YTX references, one MOTOBATT QuadFlex model covers multiple engine sizes and terminal layouts, cutting the number of part numbers you need to keep on the shelf. ## MOTOBATT QuadFlex: one model, several terminal configurations What sets QuadFlex technology apart is its 4 flexible terminal system: you can connect your motorcycle's wiring in whichever position you need, without having to hunt for the exact reference with reversed polarity. It's sealed, maintenance-free AGM, suitable as a direct replacement for several original YTX and YTZ codes. ### MOTOBATT QuadFlex models and what they replace - **MBTX9U** (10.5 Ah) — replaces YTX9-BS and YTX12-BS. - **MBTX12U** (14 Ah) — replaces YTX12-BS and YTX14-BS. - **MBTX20U** (21 Ah) — replaces YTX20L-BS and YTX24HL-BS. ### How to choose your MOTOBATT QuadFlex Find your motorcycle's original YTX/YTZ code and check which MOTOBATT model replaces it in the table above; the 4 flexible terminals let you wire it in whatever orientation your bike uses.
