Default Yep - I replace all my batteries between 3-4 years
and the cars get garaged so they are not temp cycled as much

Default Cold temps reduce a battery's capacity (temporarily)
Cold temperatures reduce the chemical reaction that produces current. At 0 deg F a good battery has about 1/2 it's capacity available to crank. So, a battery can to fail to crank the car at low temps but will be OK at higher temps. It it's old and weakened the problem will be seen at higher temperatures.

Excessive heat damages the battery through electrolyte evaporation and plate corrosion. Salty climates can contribute to the corrosion that degrades the battery. Overcharging (bad voltage regulator) can damage the battery as well.

Sounds like you should get a new charger; one you can trust. Not worth the stress

I replaced mine at 5 years and 5 months. It was starting to get weak.

Default I replaced mine when my battery was 6 years and 6 months old.
Never had a problem or symptoms that warranted changing the battery. Replaced it for peace of mind.

Default how to avoid stealership
They want over $300 for replacement. Besides DIY, what is a cheaper but reliable alternative?
