Auxiliary battery replacement
T20 bit
10 mm
Magnet
Expansion rivet removal tool or screw driver
Battery Terminal 6Nm = 53 in lbs
Same safety tips as the main battery
With ignition off, store the key fob away from the car. At least 7 ft away or 2m
Always check for damage on cable or terminals
When taking the vent tube off be careful, as the battery vapors emitted will damage surrounding components. It's a good practice to cover it and rout it correctly
Negative is usually black and positive is usually red or check on the battery + or - signs
Never let your tool touch any metal while removing the terminals, could cause spark, damage and/or may even get the tool welded to the terminals, specially if you touch both terminals with the tool
Tuck your terminals out of the way so they don’t bounce back and get in contact with the terminals again
Always start with the negative terminal first
Cover the positive cable so it doesn’t touch any metals
Put the vent back on the battery
Always seat the terminals all the way down. Don’t pound the terminals on, because it can cause internal damage
Always pay attention to torch specs. Some terminals are very fragile
Check on the fabrication dates when you buy it. Month and year. No later than a month built
