Motorcycle electrical systems demand a battery that delivers reliable cold-start performance without the maintenance burden of conventional wet-cell units. The Exide AGM12-9 is a factory-sealed, Absorbent Glass Mat (AGM) motorcycle battery rated at 12V and 9Ah (C20), with a cold cranking amplitude of 120A (EN), purpose-built for powersport applications where vibration, orientation sensitivity, and acid spillage are genuine operational concerns.
Manufactured by Exide Technologies under the AGM Ready programme, this battery employs a glass-mat separator that immobilises the electrolyte within the cell plates. This construction eliminates free acid, rendering the unit completely leak-proof and spill-proof. No initial acid filling is required and no periodic water topping is needed – the battery is shipped in a fully charged, ready-to-install condition, with technology that also supports start-stop cycling subject to vehicle label verification.
The AGM12-9 measures 135mm (L) × 75mm (W) × 140mm (H) and is housed in a C43 case with a B00 hold-down configuration and Polarity 1 layout. It replaces or cross-references the following part numbers: YTX9C-BS, YB9A-A, YB9-B, 12N9-4B-1, 12N0-4B, YB7-A, 12N7-4B, 12N7-4A, and 12N7-4A-1. Weight is 3.2 kg.
This battery is one of ten AGM Ready variants available from Exide Technologies on PartsForMachines, including the ET12A-BS, ET12B-BS, ET14B-BS, ET4B-BS, ET7B-BS, ET9B-BS, ETR4A-BS, ETX12-BS, ETX14AH-BS, and ETX14AHL-BS, covering a wide range of powersport fitments.
