Battery Replaced but not turning on

[tanouselkareh]

Evening Team,

So quick question... I have my old HP Dv7 Pavallion Laptop and I just replaced the battery. The old battery died several years ago and I never needed to replace to because I just use my tablet in place of it. However, I would love to repurpose my laptop.

I have had it charging for several hours now with the new ion lithium replacement battery and just want to know two things; is this going to work and if so how long should I leave it on the charge before I attempt to reboot?

Hi @tanouselkareh,

Thanks for stopping by the HP Support Forums! 🙂 Good day.  I read your post about requiring battery enhancement information. I will be delighted to assist you here. 🙂

Stupendous diagnosis and spectacular analysis of the issue before posting.  Kudos to you on that score. It is always a privilege to work with technical specialists like you. 🙂

We greatly value your relationship with HP. You are a valued HP customer and we appreciate you greatly for doing business with HP. I take it as a privilege to share this platform with you. 🙂

• First off, to answer your question, yes, replacing the battery was a terrific idea to extend the life of the notebook. If it is the correct compatible battery for your notebook, it should work.
• After all, we don’t live in Bill Gates neighborhood. 🙂 We need to make the notebook reusable. 🙂

• The battery initially needs to be charged for about 7 hours roughly with the charger plugged in and the unit turned off. (only for the first time)Then you could use it on battery power the following day.

Some tips to enhance battery life:

• Please always charge the battery to 100% and use it on battery standby.
• Then when the charger is plugged in, there is no issue here. However, when you continue to sue the computer on battery standby, make sure to drain down the battery to lower than 15% before recharging the battery again.
• One in a while, for example, once in 15 days, save up all your work when the battery shows a notification that it is low on charge and allow it to drain down completely before charging again, which enhances the battery’s life and performance.
• This across devices like camera, cell phone or notebook.
• This is because, with each charge and discharge, the battery completes 1 charging cycle and the life cycle of the battery diminishes.
• The battery has a life cycle of a standard amount of charges and discharges only. (depends on the size of the battery)
• It is never a good idea to charge the battery to 100% and deplete  30% of its charge and connect the charger to it again.
• Because you lose out on 70% of its remaining charge and complete only battery charging cycle if you plug the charger back to charge the battery.
• As it goes from 70% to 100% charge and completes 1 charging cycle.
