How to install BTI Battery

Installing the BTI Battery is a straightforward process that restores notebook power with a clean, reliable power source. For best results, follow these general steps aligned with most notebook models. Always refer to your device manual for model-specific instructions and safety warnings when handling internal components.

1. Power down completely and unplug all cables from the notebook. Allow the device to cool if it has been in use. Disconnecting power prevents shocks and data loss during replacement.

5. Align the BTI Battery with the connectors and mount it securely in the battery bay. Press firmly to ensure a solid, even seating, then reattach any locking mechanisms or restraints to keep the battery in place.

6. Reattach the notebook’s back cover or battery panel, reconnect power, and power on the device. If the notebook fails to boot, re-check connectors and reseat the battery to confirm proper installation. Run a calibration cycle if your device’s battery management system recommends it, and allow the battery to reach a full charge before normal use.

Tips for optimal performance: keep the notebook in a cool, ventilated environment during charging, avoid exposing the battery to extreme heat or cold, and use the original charger or a compatible high-quality charger to maximize charging efficiency and preserve battery health over time.

Amazing!
Size: King (Pack of 1)
Such a great pillow I’m buying another one! You can add or subtract stuffing to your liking. It’s really nice quality, quilted and soft. Best pillow ever. Super comfy and great sleep. Pretty firm with all the stuffing. Perfect the way it came with stuffing on the side. My husband loves it and now I want one.

Totally worth the money

Right off the bat, the packaging is absolutely adorable and felt like I was buying a premium product. I love that this pillow is adjustable and as a side sleeper, I needed a pillow that is both firm and supportive of my neck. This hits all the boxes. We will be buying more of these for our bed!

As advertised for once! Lol
Color: Cooling Blue Cover, Size: Queen (Pack of 2), Color: Cooling Blue Cover, Size: Queen (Pack of 2)
Queen size set of 2 pillows, I'm giving it 5stars first bc it has a good length and width!! If you've ever bought memory foam pillows before you know some are small!! Anyways after having it for 5nights, we loved that me and my huddy could adjust the Thickness amount we had in it to our needs, me needing a thick pillow and my husband needing a flatter one. So this was perfect for that. So far its nice to sleep on, stays cool, doesnt get hot. I would say its on the frimer side but softer the more foam you take out! Really its just good for the amount you spend!! Will it last 10years probably not but what does now a days. This is the only time my huddy n I bought the same pillow and both love it so I'm just still in shock it worked out so well!!

Adjustable pillows
Color: Cooling Blue Cover, Size: Queen (Pack of 2)
I love these because they don't go flat. You can pull out whatever you need to make them comfy for you. They come in two different layers. So you have that protective cover over the main case that holds the memory foam. They're amazing to sleep on. I have had these last for years without going flat. If you hate flat pillows this is the way to go. They are very easy to wash. You just have to separate layers. They are very thick, you can adjust the thickness. Everyone in my house has at least one. They are worth the money. I have never had to replace them, because they went flat.
