The provided context does not contain specific instructions on accessing the battery on a Zontes ZT125-G1. However, it does mention a "BATTERY HOLDER TRAY" for this model, which suggests that the battery is secured in a tray. Typically, accessing the battery on a motorcycle involves removing the seat or side panels to reach the battery compartment. For exact steps, refer to the motorcycle's service manual.
