NOCO GENIUS Repair Way

Taking the Repair mode for a spin using a NOCO GENIUS 5, attempting to recover an old battery. This is a follow-upwards to my previous review of the NOCO GENIUS charger/tender series.

The accessory bombardment from a friend'south Toyota hybrid was dying as before long as the hybrid arrangement was disabled. He had already replaced the battery, so it had already been disconnected and removed from the vehicle. Perfect candidate for experimenting with the NOCO GENIUS charging and repair modes.

Panasonic S5523R Hybrid Battery

The battery was a Panasonic S55D23R, offering 335 CCA and 51 Ah. Not hugely capable, but its simply responsibilities were starting the hybrid system and running 12V electronics when the hybrid organisation was disabled. It lived in a sheltered compartment in the torso, so despite being old information technology was impeccably clean.

Initial Measurements

I used a multi-meter to measure out bombardment voltage before starting.

Dead 12 Volt Car Battery

The battery was producing iv.54 volts DC (VDC). That's pretty danged dead.

Normal Charge

NOCO recommends running a battery through a normal charging bicycle before attempting to repair.

Connect the positive clamp, then the negative, then plug in the charger.

Notation: I plugged the charger into an inexpensive power meter to observe the voltage, amperage, power, and full kWh used throughout the charging and subsequent repair process.

Measuring Battery Charging Current

The battery in question was a standard lead-acid (read: non-AGM, non-lithium) diversity so I pressed the Mode button once until the 12V indicator illuminated. Charging commenced shortly later on.

I didn't shoot a video, but with ability meter you can watch the current pulse. The battery volition take 0.5A for a second or two, then 0.7A for another 2nd or two, and so dorsum to 0.5A. And as the charging process progresses the amperage levels increase gradually, but e'er pulsing.

The User Guide provides estimated charging times based on bombardment size (Ah) and a 50% depth of discharge (DOD):

20 Ah in 3 hours
forty Ah in 6 hours
80 Ah in 12 hours
100 Ah in xv hours
120 Ah in xviii hours

Extrapolating, 60 Ah might have taken 9 hours. Temperature likewise impacts charging times. Information technology was warm outside for the duration of the experiment. And this battery was significantly more discharged.

It took about two (2) days for the green Charge LED to exist solid light-green, indicating charging complete. Information technology'south entirely possible it finished overnight, but I wasn't in a rush to gather exact timings. That'due south ane of the perks of smart battery tenders, once they're done with the charge you can leave them connected indefinitely without worry or damage.

I unplugged the charger and took a reading with the multi-meter: the battery was producing 13.16 VDC. An hour later with the clamps still on, the 13.04 VDC.

The power meter reported a range in power between 2 and 93.6 watts during the charging catamenia, consuming 0.946 kWh in total. From my utility company, that represents around $0.11 worth of electricity.

Repair Mode

With the battery charged, it was time for repair mode.

Press and hold the Mode button for 3 seconds until the 6V LED illuminates, then press the Way button in one case more to switch to 12V Repair fashion. A red LED will illuminate.

The repair way lasted about iv (four) hours, only every bit the User Guide suggested. Toward the end I could hear the tranquillity bubbling sounds of electrolysis emanating from the battery; no steaming, venting of gases, or warmth to the battery casing. The charger returned to Standby manner after completion.

The bombardment was producing xiii.twenty VDC.

The power meter reported a range in power between 2 and 18.three watts during the charging period, consuming 0.046 kWh in total. From my utility company, that represents around $0.005 worth of electricity.

Subsequent Measurement

To come across how the bombardment was property the charge, I took measurements for a few days after completing the repair.

0 hours: 13.20 VDC
24 hours: 12.94 VDC
48 hours: 12.84 VDC
72 hours: 12.77 VDC
96 hours: 12.73 VDC

The battery appears to be losing 1-2% of its initial accuse every day. If discharge continues at that rate, the vehicle would need to be driven (or battery otherwise recharged once per week) to stay in usable condition. I wouldn't apply it equally a primary bombardment in a vehicle, but left tended it could exist put into "service" every bit a backup battery should my friend come across trouble with his new battery.
