The Honda Rancher TRX400FGA AT uses a 12V battery rated at 12 amp-hours (Ah). According to the official specifications, the acceptable voltage range when fully charged is between 13.0 and 13.2 volts. If the battery drops below 12.3 volts, it is considered in need of charging. Standard charging is done at 1.4 amps for 5–10 hours, while a quick charge can be performed at 6.0 amps for 1 hour. The system is also designed to limit current leakage to a maximum of 1 mA to preserve battery life. These specs are tailored for a sealed lead-acid (SLA) type battery commonly used in powersports applications.
Be sure to match both the voltage and amp-hour rating when purchasing a replacement to ensure proper function and compatibility with the vehicle’s charging system.
