COX BOX / BLUE OCEAN BATTERY INFORMATION
SPECS
*As with any rechargable battery, NK Battery packs can be expected to lose
approximately 10-20% capacity per year.
Voltage (new) 12.6 volts
Weight 105grams/3.7 oz
Size 2.8 x 1.8 x 1.5 in
Operating Temp -10 to 50°C
Storage Temp -20 to 45°C
Charging Temp 0 to 45°C
For Cox Box: Battery will typically last 4-6
(typical use is ½ volume and ½ talk time).
For Megaphone: Battery will typically last 8 hours
(typical use is speaking 35% of time at volume level 6).
BEST PRACTICES
A fully drained battery requires at least 6-8 hours to reach full capacity,
Place your battery on charge whenever not in use, but avoid leaving it
plugged in for more than three days at a time.
From 0-90%, the charge rate will be around 0.5% of charge a minute.
After it reaches 90%, the charge is reduced and it will take longer to
get to 100%.
Charging indicators:
Flashing Red - Charging 1 to 10%
Flashing Yellow - Charging 11 to 25%
Flashing Green - Charging 26 - 99%
Solid Green - Fully Charged, 100%
Flashing Red/Yellow/Green - See Errors section
For Cox Box Charging:
For Standalone Charger:
»Batteries made prior to 2015 with low capacity can be helped by
rebalancing.
1. Drain battery completely
2. Set aside for 2 days
3. After 2 days, charge unit until full.
»Batteries after 2015 will “self-balance” but it is best to occasionally
fully drain and fully charge these batteries (without 2 day waiting
period) to have this happen.
»Check the “spring pins” in the charger or Cox Box battery cavity to
ensure none are stuck in the down position. If a pin is down, use
alcohol to try and work it in and out to set back to proper height.
»Dry off battery and charger before charging. Never charge a wet
battery.

ERRORS (For standalone charger)
If charger ashes red, yellow, green in a sequence
this indicates an error from high temperature or a
poor connection:
High temperature:
Move to a cooler location.
Clean any corrosion on battery pins, charging pins and battery
contacts with alcohol.
Connection Issues:
Ensure battery is seated and locked in place.
If you have to push down on battery to charge, send in charger for
repair.
Check the 4 charging pins in the charger. If any are stuck in the
down position, (while not plugged in) use alcohol and try and work
it in and out to pop back into proper height.
If Error persists, send back to NK for repair.
ERRORS (For Cox Box charging)
Hi Deg Err shown on Cox Box:
Clean all parts of the charging system with alcohol:
»5 prong CB socket, charging pins, battery
pins in CB and battery contacts themselves.
BATT ERR shown on Cox Box:
Swap battery into another Cox Box. If issue follows
battery, send in battery. If it follows Cox Box, send
in Cox Box.
If Error persists, send back to NK for repair.
STORAGE
At the end of the season, charge the battery fully,
disconnect from the charger, and store in a temperate,
dry place (between 50-80 degrees F) until ready to use.
*A fully charged battery will self-drain in 3 months. If storing longer than 3
months, we recommend charging the battery to full around the 3 month mark.
