I read the battery guide, but I still have one question.

The battery guide recommends to recharge the battery when it reaches 10%-20%. It also recommends small charges are better than large charges. Does that mean it is safe or even better to recharge the battery a 95% or 80% compared to 10-20%?

Thank for the help.

 

I'd like to know that myself.

 

Ah yes. Another question I would like to know as well.

 

It looks like this thread is never going to receive an answer .

 

Oh please help the blonde one and her friends.

 

I am not going to even read the guide I have researched independently and much of this I was aware of at some level. So here goes. The recommendation to recharge is a caution to let you now do not let it discharge so much the voltage drops called “deep discharge”. Why? It can result in a dead battery, but there are circuits in the battery that monitor voltage so in theory it should be impossible so you should not have to worry but 10% to 20% is certainly safe do as you choose. While there is nothing wrong with running battery low if you are using it you should always recharge at 1st opportunity no matter how much charge is left. Unlike the Ni-Cd batteries you do not need to “deep-cycle” so you should not do it. That is I believe the logic behind the small charge statement. I am going to assume this post is about prolonging your battery life. I am almost always plugged in, keeping the battery in is bad in two ways, full charge is not how you store to maximize life 40% is, so take it out. Temperature is problem #2 full charge at 77F reduces capacity 20% per year 40% at 32F 2% reduction. Hope this helps.

 

Wait, am I to understand that to mean that you can run a notebook, no battery, just plugged in? Sorry if thats a ridiculous question but I'm about to own my first notebook.

 

Honest Question, Honest Answer Yes.

 

Sweet. That makes all these recommendations about charging and the refrigerator so much more understandable. Thanks for the help!

 

The Battery Guide says the same thing. I decided to take out my battery and store it in the refrigerator until I need it. Thank You for the advice.

 

I have one question. After I took out the battery, it left a hole in my laptop. If I take the battery out of the laptop, is there a patch I can buy so it does not leave a large hole in my laptop?

 

lol. no. it doesnt matter if theres a hole. most batteries are in the back or on a side w/ a cover. my old skool sony laptop has a cover on the right side w/ the battery hidden inside. and my HP, has the battery in the back, so if i take it out, i cant see it.

one question about the fridge. would it be better to freeze it? or is that bad?

 

don't put it in the freezer

put it in the fridge

perferablly in a ziplock to keep moisture out (that could slowly oxidize your battery contacts)

 

Ebay for dead battery, don't know if you need to remove contacts for safety but I think that would work.

Even though I agree, the real problem happens at -40C -40F (yes they are the same) so not a critical issue. Along with a plastic bag you could put a desiccant in to control moisture I would consider this a must.

 

where do you buy those moisture absorbing packets?

 

I'll look into it, but have you ever bought a product and it comes with what look kind of like a package of sugar, those are it.

 

That's really kool. I wish we had room in our fridge. lol

 

Time to take the left overs out!

 

But as the OP asked, is it okay to recharge the battery at say 80% more or less? Say a thunderstorm is coming through, so you unplug it. Should you run the battery down to say 20% or is it okay to just plug it back in to charge back up from there?

 

I disagree with the way you interpret the original posters question, it is missing a letter, where it says “a” 95% the intended word is “at” substitute and reread. The question is not charge to 80% or 95% it is recharge at those levels to full charge. To interpret as you stated requires ignoring first two sentences. No one addresses the specific question you have asked. I read you should calibrate your battery every 30 cycles in the battery guide, this is done by full discharge recharge, does appear to be in conflict with some other advice. I will use a little common since, If you can only charge to 80% the only downside I can see is if it counts as a cycle of which you have a limited number (300-500). Remember it is recommended to not store at full charge so would think charging to 80% at least on occasion is not going to hurt. Best I can do, anyone better?

 

Okay, let's start over. I am asking this question. Say a thunderstorm is coming through and I unplug the laptop and continue using it. Say I get down to about 80% (estimate), is it okay to plug it back in (thunderstorm's gone) and start using it on AC? Or should I let it go down to say 20% (or lower) before plugging it back in. Which is better for the battery?

 

Plug it in small charge good.
