How Long Should a Laptop Battery Last?

| 1 | Just wondering as I'm beyond annoyed. I had my laptop fixed at a computer place about six months ago and bought a new battery as my old one was dead. The first one they sold me was as dead as a dodo and I had to take it back. They replaced it and it's been fine till tonight when a message flashed up after charging it saying the storage capacity had been exceeded and I needed to replace the battery! It's suddenly stopped charging. Edited by hound31 at 7:05 pm, Wed 3 Feb hound31 - 2021-02-03 19:05:00 |
| 2 | well I think you need to let them have a look at it to make sure, it could be something else like the charging circuit that's the problem king1 - 2021-02-03 19:09:00 |

| 4 | If it was a cheap laptop then the battery will be rubbish in it and won't last long. loud_37 - 2021-02-03 19:38:00 |
| 5 | lets put it this way a lithium ion battery lasts best case 14 years best case never happens as thats figures made up in a vacuum and no wind humidity or other factors. long story short. My asus stated 3 year warranty on my laptop i can still see the sticker. That was back when lithium ion usually was dead in 2 years on phones .

| 6 | I'm using an 8 year old Samsung laptop running Win7 and chrome. I buy cheap batteries off TM $60 + postage and they last between 6-12 months. When they get down to 50% of original charge I change them. I imagine I'm not managing the battery charging process properly, hastening its demise no doubt. nicc4 - 2021-02-03 21:30:00 |
| 7 | 3-10 hours. Boom boom. Do we know the brand of the laptop and of the batteries? What else was necessary to be done as part of the 'fix'? There are plenty of Chinese made batteries out there that are absolute rubbish. The manufacturers have spent more time on copying the labeling than on battery construction. Also, why did the 'computer shop' put extra software on the machine and what else might they have done? soundsgood - 2021-02-04 07:10:00 |
| 8 | I'm using a 10 year old ASUS netbook which I bought in Hong Kong and the battery is still pretty good. The computer battery software built into my operating system tells me that: Energy Full Design: 47.52 Watt hours So the battery health is still at 72% capacity after 10 years. 6 months is definitely faulty, you should take it back under the consumer guarantees act. Nobody would expect a brand new battery to crap out after only 6 months, even if it was a cheaper one. They supplied it, but it isn't of acceptable durability. tygertung - 2021-02-04 09:43:00 |
| 9 | Thanks all. I might ring them. I don't really want to deal with them again, but I'll give it a shot, I could've bought myself another cheap laptop with what I've spent on the "repairs" and battery. I'll mention the consumers guarantee act! hound31 - 2021-02-04 10:23:00 |
| 10 | 2 possibilities Either way people who are putting on CCleaner, and super antispyware aren't good techs in 2021. bitsnpieces2020 - 2021-02-04 16:09:00 |
| 11 | Another possibility if the OP has run the laptop plugged in most of the time while the battery is installed that will destroy the batteries ability to store charge very fast and you'll quickly end up with a dud battery. You MUST 'use' a battery in order for it to retain it's ability to hold charge and discharge it. nice_lady - 2021-02-04 16:16:00 |
| 12 | I've had my netbook plugged in a lot of the time for the last few years and the battery is still 72% good after 10 years. The computer should have a decent BMS on it. tygertung - 2021-02-04 16:42:00 |

A lot longer than six months, the charge controller is built into the battery itself on 99.99% of laptop batteries, and I only allow that 0.001 because you don't know what you don't know and just maybe there is a ultra rare battery made in outer Mongolia that doesn't have it internal. Which is to say there is a small board in the battery pack itself that monitors and balances each cell, when one goes tits up it shuts the entire pack down. This is why recycleing of laptop battery packs is a very viable thing, you'll get one dud and the rest are good (as long as they haven't dropped in voltage too much, then they degrade) Which btw is why you don't buy packs with an old date, odds are they haven't received maintenance charging. ronaldo8 - 2021-02-05 12:16:00 |

Well not quite. It doesn't destroy the battery as such. By that I mean leaving it plugged in and charged all the time won't suddenly lead to waking up to find it dead and throwing a battery error. Rather the number of charge/discharge cycles is reduced if you keep it fully charged. IE you'll get less opportunities to discharge it then recharge it if its held at 100% charge than if you allow it to flatten to say 20% But in essence you are right in that you shorten its lifespan "if" you do infact ever use it on battery only. Ideally you should charge to no more than 90% and then use on battery power till its down to 20 or so then repeat, that way you'll get the max charge/discharge cycles out of it. ronaldo8 - 2021-02-05 12:38:00 |

It may say 72% but how long does it last running on battery, Most batteries I've seen at 65% are buggered. loud_37 - 2021-02-05 17:39:00 |

Oh, ages, perhaps a couple of hours or so? Quite a long time anyway. It says the energy rate is 11.32 W and the battery has 34.27 Wh, so that is about 3 hours. I haven't timed it, but it certainly still lasts for a long time. It does have an Atom CPU which is designed for low power consumption and has hyper threading so still gives acceptable performance. Probably would not last as long if I was running Windows 10 as that seems to use more system resources. tygertung - 2021-02-14 07:41:00 |

| 20 | I purchased a 2nd hand Dell E6410 with a bad battery. Got it for peanuts as it happens. That was about 6 years ago and immediately purchased a new Dell 9 cell battery. I'm happy to report that it's still going strong. I currently get about 6 to 7 hours out of it depending on what I'm doing. namtak - 2021-02-26 19:54:00 |

Yes, that's probably fair enough. There are many services that run under windows that can be tuned/stopped and a number of scripts that can be had to help reduce overhead. But look at Ubuntu - a distro that is three times the size it was eight years ago. soundsgood - 2021-02-27 13:40:00 |

Yes, that sadly has ballooned as well. I stopped using normal Ubuntu after 11.04. I'm running Lubuntu 20.04 on my netbook at the moment and it seems to go pretty fast. tygertung - 2021-02-27 13:45:00 |

Was it a brand new battery? If yes they come with warranty to a certain length of time. Either repair or replace. If you cannot be sure of the quality of the battery then you shouldn't start questioning other stuff first like the laptop's circuitry. With batteries I always buy brand new original brand like phone batteries they have a finite life. With second hand laptops they often require battery replacements. Given that new laptops today are not that expensive I no longer look for second hand laptops. You also need to account that second hand laptops can be quite a number of years old with old tech that needs to be factored into the price and there are are often no warranty unless you bought it off a business but still a second hand laptop or a second hand battery ought to have a few weeks warranty if you did in fact bought off a business.

| 24 | [quote=hound31I had my laptop fixed at a computer place about six months ago and bought a new battery as my old one was dead. [/quote] So before this 6 months, it was working OK? It was also brand new? From some 3rd party laptop batteries via Google it seems they all state 12 months warranty. rayonline_tm - 2021-03-01 10:28:00 |
