Xenotronix/TLI

o
When charging a smaller capacity battery, the battery may be undercharged
because the charger switches into float charge mode too early (relative to
capacity). Leave the battery connected to the charger for 16-24 hours to finish
charging in the float charge mode, or have a unit made with a custom switch
current to match the battery capacity.
Xenotronix/TLI can make custom units, or modify our existing units, to exactly match
your charging needs. Call our sales department for technical information and pricing.
Following are
some
of the modifications we can perform:
o
Reduce charge current to match your battery capacity
o
Change switch point to match battery and charge rate
o
Adjust float and charge voltages for special conditions or batteries
o
Make charger into a float charger (single stage)
o
Make charger into a parallel charger (for use with loads in parallel with a battery)
o
Provide custom cables and connectors
o
Private labeling
TROUBLESHOOTING
NO INDICATOR LIGHT - If the indicator light is dark, check to see if the receptacle is
controlled by a light switch or power strip switch. If all else appears normal then the
charger probably needs repair or replacement.
NO CHARGE INDICATOR, NOT CHARGING - If the charger will not go into charge
mode (yellow indicator) then the battery is probably already charged. Try again with
another battery which you know is not charged.
FAULT INDICATOR - If the indicator light is red then either the outputs are hooked up
in reverse or shorted together – make sure of the connection to the battery. Note: A nearly
completely dead battery (less than one volt) looks like a short to the charger. If you
suspect the battery is dead, leave the charger on the battery to see if it will go into charge
mode. The charger will deliver a small amount of current into a dead battery and may
eventually go into normal charge mode and recover the battery.
CHARGER WILL NOT SWITCH INTO FLOAT MODE - If the charger will not switch
into the float mode, even after 24 hours, then the battery is probably damaged and is not
properly accepting the charge. Remove the charger and check the open circuit voltage of
the battery - there should be about 2.15 V/cell for a properly charged battery (divide the
battery voltage by two to get the number of cells). If the battery voltage looks correct
then you may be trying to charge a battery which has too large a capacity for the charger
(see charging notes and tips).
