Wiring & Setup:
MAINTENANCE
It is recommended to periodically inspect your wiring schematic and ensure all bolts and terminals are
properly installed and tight. Depending on the discharge/charge rate you may experience loosening of
terminals due to thermal expansion. If this occurs you will need to re-tighten your bolts.
The main terminal bolts on the SFK-275HP are under the battery case, to access this you will need to
remove the 4 top M4 countersunk screws. Once the case is removed you can use a M8 ball-end hex driver
or L-wrench to check that they are snug and are making proper contact with the copper conductor ring.
If they are loose, you will need to tighten them, note loose bolts will cause the battery terminals to heat up
as they become a source of resistance, this must be addressed or it will cause permanent damage to your
battery and can lead to a fire hazard.
You should also check that the battery is kept away from water & moisture and that there is proper ventila-
tion to maintain temperature & humidity. These issues can lead to battery performance and degradation if
not resolved; they may not be apparent immediately, but will have a cumulative effect in the long term.
