Battery Life
« on: June 24, 2012, 07:45:05 pm »
I've always been told if you don't let your phone, iPods, etc. battery die before charging it that it will ruin the battery life is that actually true?

It's called battery memory therefore yes it's true my old laptop battery would only last 5 minutes max before dying so my new ones always on charge so it never runs down and creates battery memory.

I dunno about that, my laptop battery only lasts about 3 seconds before it dies.

Actually, that advice isn't accurate, and likely doesn't apply to any electronic device owned by anyone on this forum.

It's kinda-sound advice for NiCad batteries, which are typically only found in the form of rechargeable standard batteries (AAA, AA, C, D, etc), and even those aren't always NiCad.  Lithium Ion rechargeable batteries, which power every portable electronic device made in the last decade (including laptops and most cameras), have no memory effect whatsoever.  The reason people still apply it to all battery types is because, to put it bluntly, the general public is dumb and technicians are lazy.  Too many people have been told "all rechargeable batteries/devices exhibit the memory effect" by underpaid techs who don't want to explain that there are three different rechargeable battery types with three different charging behaviors (excluding stuff like lead-acid car batteries).

So, check the type of batteries used by the device (they're always labeled), and then do one of these:

-If it uses lithium ion (LiOn) batteries, you have absolutely nothing to worry about, discharge and recharge however you want.

-If it uses nickel cadmium (NiCad or NiCd) batteries, partial discharges will diminish battery capacity, but they can easily be reconditioned.  Advanced chargers for AAA/AA/C/D batteries will have a conditioning mode, so if performance is starting to suffer, run that.  If it's an electronic device with an integrated charger or a proprietary battery, run it completely dead every once in awhile if performance suffers.  Also, avoid "timer" chargers, they'll destroy your batteries.  Get a smart charger instead, it's worth the investment if you have something that takes NiCads.  Lastly, don't run NiCads completely dead for more than a few minutes, or in anything less complex than a late-1990s cellphone, this can cause their polarity to reverse, rendering them unchargeable.

-If it uses nickel metal hydride (NiMH) batteries, follow everything I said about NiCad batteries, although NiMHs don't exhibit any sort of memory effect nearly as noticeably as NiCads, so it takes a lot of partial charge and recharge cycles to make any sort of impact.

-If you can't get to the battery, or you're not sure, basic internet searching ought to reveal the answer.  If it's a sealed-battery electronic device made in the last 5-10 years, including any Apple product, I can almost guarantee it's lithium ion.

There is one thing you have to worry about. My Lithium Ion battery for my blackberry started to expand, pushed against some hardware and caused a white screen. Now I have to buy a new battery, and I cn't find a place that sells them.

My old laptop, which was a Dell Inspiron 9100 that was made in like 2003, had a Nickel Cadmium battery, and the last user apparently discharged all the time because it never lasted more than five minutes off of it's charger. But I don't have to worry about that now because my new laptop has a Lithium Ion battery that last six and a half hours.

I got the Inspiron 1545. It has a Lithium Ion battery that lasts a whopping ten seconds.

I've never had any issues of rechargeable batteries dieing on me despite how I use them (I never let them completely die and a lot of the time never let them fully charge either).  Or I just leave them plugged in forever.  :fox-:P:
