Braille 12V Lithium Charger/Maintainer
6 Amp electronically controlled Maintainer/Charger
For the use with Braille 12v Lithium Batteries only SKU#: 1236L
OPERATION FOR CHARGING & MAINTENANCE:
A. Connect charger to a 110/220 VAC wall socket (Red & Green LED will
illuminate)
B. Connect DC output cord to battery terminals or connector
C. LED1 is red all the time (power), LED2 is red when CHARGING.
D. When LED2turns “green”, battery isfullycharged &in “maintenance mode” for
storage or when not used regularly.
E. Keeping battery at or near 100% results in maximum life.
FEATURES:
A. Short circuit protection, charge output will not enable and will not spark
if terminals touched together.
B. Overload protection, current-limited.
C. RPP “ Reverse polarity protection”, connecting a battery in reverse
does no damage to charger. Fused design.
D. Automatic multi-rate charging, CC/CV profile with Pre-charge @1.8a.
E. Simple Two LED display; LED1 Red (AC Power on), LED2 Red (charging) and
Green (full).
F. Low voltage protection, charger will not enable if battery’s voltage is
below safe charging thresholds. CONTACT Braille Battery for support.
NOTES:
A. Designed for Braille Lithium batteries only, never on lead/AGM batteries.
B. In Case battery is FullyDischarged: Damage can occur when any battery
is discharged below 10 volts (considered 0% on 12v lithium battery). If this
occurs, charger has precharge/revival mode (flashing LED2) to slow charge back
to 10v, testand then charge at 6 am psto full. (assuming no damage)
C. To calculate charge time you must take the battery amp hourand divide it by
the Charger Amp hour output which will equal the amount of time to fully
charge based on a 0% level of the battery. Example: (15 amp battery =10 amp
charger = 1.5 hours to full charge from 0%)
D. If battery does not get back to full charge (Green) in the amount of time
calculated, then there is likely damage, disconnect charger. Charging longer
will NOT get it charged, if damaged. CONTACT Braille Battery for support.
E. Always place the charger in a well-ventilated and dry environment
F. Do not cover or seal the charger, the aluminum housing is the heat sink to
properly cool the charger.
G. Charger is thermally protected, Certain model chargers the fan will operate
only around 40°C or 104°F degrees.
H. Only use a proper heavy duty extension cord.
I. CHARGER WARRANTY CAN BE MADE VOID ALONG WITH THE BATTERY WARRANTY IF ANY
MODIFICATION HAS BEEN DONE TO THE CHARGER THAT RESULTS IN FAILURE (ie: CHARGER
ENDS, “QUICK CONNECTS”, FAN MOD, CABLE EXTENSION, ETC)
