Question

Laptop Battery

Apr 18, 2017 9:33AM PDT

HP DV7 laptop
I left the laptop on and left the house for several hours. Did not notice when I left it was not plugged in. When I returned it was dead due to the battery being fully discharged. This oversite caused the motherboard to be destroyed.
Bought another hpdv7 on a good deal from ebay. No HDD ,Power cord or battery. Used the power cord from my dead one and the Hd. Did a clean install of win 7 ultimate and it it working great.
Now my question. If I put the drained battery from my non working DV7 into the one I just bought, is there danger of doing damage or should I bite the bullet and get a new battery?

Let's cut that off at 2 years old.

If the battery is over 2 years old, let's not chance it as the battery is only rated for 300 cycles and you have a chance it could be gone. Not worth the risk.

It's some i7 powered thing that has a GPU (unknown which one) but we upgraded from HDD to SSD and bumped the stock RAM to 8GB. It's good enough for The Sims 3 and 4 which my wife plays.

I try to remember to get the canned air to the vents on the 1st of the month and it's now 6 years old? The battery looks to be about 70ish percent of capacity but it does not run on battery often.

-> My tip here? Keep up with the canned air to the vents as you can since it is one hot machine.

Canned air is one of my regular routines. I have 5 laptops and 4 desktops running. I live in a gated community and we have several camera that broadcast through the internet. I use the laptops to monitor what's going on as I am on the security team.
Frequently I get calls from windows tech team saying they have detected a virus on my computers. My general statement is "Which one, as I have at least 5 running". Their standard answer is "The one you are looking At" I answer " I am looking at 5. They hang up

First, let's look at the definiton.
A battery is a container consisting of one or more cells, in which chemical energy is converted into electricity and used as a source of power. Now, I am no science teacher, but I can see here that it says the battery is a container, meaning it holds something. Your battery also connects to your computer, whether it be a small one or a large one. What you should do is check with some computer company, suggestively someone who is good with batteries at that company, and get it tested (Your old one). If it is said to still work correctly, then put the old battery in. Now, if you didn't backup your data or save it all to a form of removable media, then you'll need your battery for all of your files. It shouldn't be fried because of the motherboard, for a number of reasons. A sensible person wpuld say, "The battery is connected to the motherboard, so it must've been fried as well!" This is a no-no. The battery is safe from harm unless you continously drop it or break it physically somehow. Otherwise, it is just a power source that helps your computer turn on. Try this, and I hope it helps!
