will cause an imbalance and the batteries will suffer a shortened lifespan.
•
Trusting a State of Charge (SOC) meter, which can lose calibration over time and give you
false readings. You need to verify specific gravity and or verify the charge voltage is being
met. Never fully rely on the SOC %; it is just a good, quick reference.
•
Routinely using more than 50% of the capacity of the lead acid battery. Using more than
half the battery capacity drastically shortens the batteries life; occasionally is fine, but daily
will kill lead acid batteries in months.
•
Not leaving ample space between cells for cooling. We recommend at least one inch
between the cells for cooling. Ask the battery manufacturer what they recommend.
•
Not having enough charge current to properly charge the size of the battery you have.
Consult the battery manufacturer for the minimum charge current.
•
Using tap water or other liquids instead of distilled water in a flooded battery. The minerals
in the tap water will destroy a battery.
•
Not verifying the temperature compensation neutral point (typically 25°C) and the milli volts
per degree C per cell (typically -5mV).
•
Not verifying you are charging to the voltage supplied by the battery manufacturer.
•
Not fully charging your lead acid batteries at least once a week.
•
Failing to keep all connections clean.
WIRING REQUIREMENTS
•
The NEC (
National Electric Code, ANSI/NFPA 70
) for the United States and the CEC
(
Canadian Electrical Code
) for Canada provide standards for safely wiring residential and
commercial installations. The NEC/CEC lists the requirements for wire size, over-current
protection, and installation methods.
•
Do not mix AC and DC wiring in the same panel unless specifically approved/designed for
both AC and DC wiring. Where DC wiring must cross AC or vice-versa, try to make the
wires at the crossing point perpendicular (90 degrees) to one another.
•
DC wires to and from the Barcelona must be protected as required by code. This can be
done by using jacketed wires or by feeding the wires through conduit or a conduit box. The
Barcelona Breaker Box satisfies this requirement.
•
Always check for existing electrical, plumbing, or other areas of potential damage prior to
making cuts in structural surfaces or walls.
•
Wiring should meet all local codes and standards and be performed by qualified personnel
such as a licensed electrician.
•
DC over-current protection must be provided as part of the installation.
•
Use only copper wires with a minimum temperature rating of 90°C.
