Am l unfairly blaming my battery

How is your ground cable?

How is your ground cable?

Seems fine. After the initial start in the absurd cold this morning it has been starting like normal.

Back to original and post# 5. Was it cranking slow or cranking longer? Those are possibly different scenarios.

Longer may be from dirty fuel injectors, time for spark plugs, when was last time valves were checked/adjusted? Longer may also be from fuel pump losing pressure when it sits overnight. My daughters has that now. First start is extra cranks as not enough pressure for correct spray pattern/mixture to ignite. Factory fuel pump is like $500+ for the part, aftermarket ones less but hit or miss on quality/reliability.

Are you referring to ground cable on battery? If so, not that one. There should be multiple ones. If you have any underneath the car, it maybe oxidized from salt etc. Your starter should have ground cable.
Sorry, -19f is not absurd cold. Winters became warmer and people forgot that those temperatures were normal before.
Unless you are driving really short distances and with that your battery is weakening with each trip. But at 220k, I personally would change all ground cables.

It was weird. My family members said that theirs took much longer to crank. Mine cranked a second or 2, completely stopped cranking for a second, began cranking again for 2 seconds and started.

I am wondering about the fuel pump because l just got P0171 code on my way back from the store.

Fuel pump will maybe show as first start or eventually no start. The P0171 may be multiple things like vacuum leaks, dirty fuel injectors, cracks in the air tube between air filter and throttle body and multiple others.

The starters wear, crank slow until they don't crank. It doesn't matter what larger or new battery you throw at it or how clean the connections are. Take it from someone that has changed a couple starters on 2.4L CRV's, same motor as yours.

You have 14 years and 220k on the original. MANY 2.4L Honda's are getting changed a second time at that point.

It could also be a one off, due to the cranking issue; the code may even clear on its own.

Since you've been dealing with apparent battery issues, I'd suspect that the lean code could be related to low fuel pump voltage or low fuel injector voltage, or both. Test the battery voltage while the engine is running. It should be around 14.0 to 14.5 volts. If it's a lot lower than that, it would point to an alternator problem.

With the Honda's you need to turn the headlights on to get full voltage to test (or to charge). The electronic load detector (ELD) or the sensor on negative terminal depending what you have adjusts alternator output for what it sees. That has driven many people crazy trying to diagnose and also results in incorrectly saying bad alternator.

It also drives audio people crazy as they want full volts for the amps etc. and if battery has enough charge (according to what it sees), teh alternator happily hangs at 12.8V so you can get an extra .001 mpg.

Invest in a battery tester. That way you can definitively eliminate the battery as the culprit and determine next steps for resolution. Batteries and vehicle components are stressed in extreme temperatures, both cold or hot. They may sound different but could be fine at "normal" temperatures. Last battery I replaced was an original AGM on an older Mercedes E350. Battery turned engine but strange things started to happen. Battery tester advised the battery needed replacing. With the new battery everything returned to normal.

Modern vehicles are complex and rely on a good supply of juice to operate correctly.
