FEATURES

AC/DC Delta Peak charger with dual independent outputs

Discharge function allows you to get the most out of your batteries

Charge two batteries at the same time – even if they are different voltages
and/or battery types

Charge and discharge at the same time (discharge on channel A only)

Charges NiCd, NiMH, Lithium, and Lead Acid

Large LCD screen shows: Battery Status, Battery Voltage, Charge Rate,
Peak Threshold in mV, Capacity in mAh, Number of Cells in Pack, Time in
Minutes

 For 1~8 cells any capacity battery (NiCd & NiMH)

Selectable charge rate with 0.10 Amp increments from 0.20 Amps to 5.0
Amps

Selectable discharge rate with 0.10 Amp increments from 0.20 to 4.0 Amps

Selectable peak threshold in 5mV increments from 5 to 50 mV

Cooling fan keeps components cool for continuous charging

12-bit Analog to Digital converter greatly improves measurement resolution

Digital Signal Processing filters out noise and provides better measurement
accuracy

MRC’s patented MicroPeak technology keeps batteries cooler
