The CH5050 dual bay, simultaneous smart charger/calibrator is a standalone unit which provides the capability to carry out charging and fuel gauge calibration on any two "N-Series" Inspired Energy batteries at the same time.

The CH5050 works with every smart, standard Li Ion and NiMH battery in the Inspired Energy "N-Series" portfolio irrespective of size, shape, voltage, or capacity. - So you can recharge a 12V NiMH battery while recalibrating the fuel gauge on a 3.6V Li Ion battery if you wish.

With its multi-voltage power supply, the CH5050 works throughout the world. Variants are available for use in North America (CH5050A) Europe (CH5050E), the UK (CH5050U).

Calibration:
Smart battery packs have a highly accurate on board fuel gauge. Under certain operational conditions this fuel gauge may drift and begin to lose accuracy. The onboard battery electronics keep a log of this drift and the CH5050 reads this value from the smart battery when the battery is inserted.

If fuel gauge recalibration is recommended by the charger (indicated by a flashing red LED), the user can press the button on the front of the CH5050 to initiate a recalibration cycle.

A special version: CH5050CAL is available which will adjust the battery state of charge to 30% for Shipping under IATA Packing Instruction 965

Operation of the CH5050CAL is as follows:
To set the battery state of charge at ≤30% for shipping:
Place the battery into the slot. The battery state of charge will be automatically adjusted (by charging or discharging). When the green LED stops flashing & remains solid, the battery is at ≤30% SoC.

To recalibrate the fuel gauge & charge to 100%:
Place the battery into the slot & press the recalibrate button. When the blue LED stops flashing & remains solid, calibration is complete & the battery will be fully charged. Note: recalibration times are long. Do not remove the battery part way through or the process will need to re-start

Recharge Times:
Different battery packs will require differing recharge times. The times given below are for a full charge from 0% to 100% state of charge. They are valid for all variants and custom hybrids of each battery model. (For example the NJ1020HP has the same recharge time as the NJ1020.
CH5050
Recharge Time (hrs): One slot,  Recharge Time: (hrs) Both slots, Max. Calibration Time (hrs)
NB2037 - 3½, 3½, 25
NC2040 - 3½, 3½, 23
ND2017 - 6, 6, 35
ND2053 - 4, 4, 65 (Yes, 3 days & nights!)
ND2054 / ND2034 - 3½, 3½, 22
ND2057 / ND2037 - 3½, 3½, 33
NF2040 / NF2030 - 3½, 4½, 30
NH2054 - 3½, 6, 30
NH2057 - 7, 7, 40
Ni2020 / Ni2040 - 3½, 5½, 35
NL2020 - 3½, 5½, 35
NL2024 / NL2044 / NL2054 - 3, 5½, 29
NJ1020 / Ni1030 - 1½, 3½, 12

Due to the long time required for fuel gauge recalibration we recommend performing recalibration over a weekend or a similar extended period of non-use.

Why are the recalibration times so long?
Two factors contribute to the long recalibration times:
- The battery must be discharged through a fixed resistor. Higher voltage batteries will discharge at a faster rate than lower voltage batteries (Ohm's law) this is why the 14.4V batteries recalibrate fastest & the 3.6V batteries are the slowest.

- The charge & discharge process includes periods of rest which enable the impedance tracking firmware within the battery to do its work.
