I've had to replace my Dell Latitude E550's battery three times in just eight months, and each new battery starts losing health after only a couple of months. It's really frustrating! The laptop has a Samsung SDI lithium battery (model DELL7FR5JD9C). I've checked, but the charge cycle count isn't listed. I'm not sure what could be causing this rapid battery deterioration. Could it be related to usage or the batteries themselves?

Could you provide more details about your laptop model and how you use it? Knowing the charge cycle and battery manufacturer can help diagnose the issue better.
Are your new batteries the same as the original one? There are lots of cheap replacements that might not perform well.
Do you ever place your laptop on something soft like a bed or pillow? That can block airflow and cause overheating, affecting battery life.
Nah, I keep it on my study table or on my lap where it gets good airflow.
Make sure you're not leaving your laptop plugged in all the time or letting it fully discharge to 0%. Batteries tend to degrade faster when kept at extreme charge levels.
I don't leave it plugged in often. I usually let it discharge to around 20% before I charge it back up to about 90%.
A genuine Samsung battery should be reliable. Just to be safe, make sure you're not buying counterfeits that are really cheap.
I've purchased from different stores each time, so it seems unlikely they're all selling counterfeits. Can you recommend a reliable place to buy a trusted Samsung battery?
Yes, each replacement is identical in model and vendor.
