INSTALLATION QUICK TIP Never put the lock washer between the cable and the terminal. Warning! The cable end must be directly in contact with the terminal. INSULATED TOOLS: USING INSULATED TOOLS AND Failure to do so may result in a melted terminal and voiding of REMOVING JEWLERY WHILE WORKING AROUND TERMINALS your warranty.
INSTALLATION DIAGRAM 3 2.2 SPEEDCAPS™ AND VENT CAPS Installing U.S. Battery Mfg. Co. Bayonet Caps SpeedCaps must remain securely installed at all times unless topping off cells with distilled water or checking the specific gravity of the electrolyte. At no point should the caps be left on the battery in the open position.
SERIES/PARALLEL cycle batteries is 0ºF to 120ºF(-18ºC to 49ºC). The recommended operating temperature range for US Battery AGMs is -4ºF to 122ºF (-20ºC to 50ºC). Temperature plays a major role in battery usage. Hot batteries will deliver more capacity, but with diminished cycle life. Cold batteries deliver less capacity and are harder to charge.
CARE AND MAINTENANCE The following information will help prevent the majority of issues that are known to DIAGRAM 4 cause premature failure.
