    Battery suddenly & completely dead - Won't accept charge at all


    The battery in my Toshiba notebook has been fine. Holding a charge for 2 hours or more. The other night running off the AC adapter I noticed the battery level was at a flat 0%.

    To see if the problem was charging circuitry, I found a suggestion about pulling the battery out, powering up the notebook, and leaving the battery out for a while. Then to insert the battery while still powered. If the notebook immediately shut down, it would be an indication that the charging circuitry was at fault. I guess I'm good there as that didn't happen.

    At that point I left the battery in for a few hours to see if that process might have kick-started charging again. But it fails to report any charge at all no matter how long I leave the notebook running on AC.

    I haven't found any other information on a situation like this, and am guessing the battery just suddenly bit the bullet.

    Has anyone seen a situation where that may not bee the case?

    Thanks for any feedback

    Laptop batteries seem to last about 1 month past the warranty date. I have never had a laptop battery last more than 3 years in daily use.

    Suggest you look for a replacement if you need to use your Toshiba on the go. Avoid the el-cheapo batteries that are all over Amazon and DON'T buy a used battery unless you personally know and trust the seller.

    That's been my experience with batteries that aren't OEM. Those cheapos can take longer to charge, don't hold a charge as long, and keep the device running for shorter and shorter amounts of time compared with the OEMs

    Odd that the battery died all at once, and not slowly over time. I've never seen that before. And it's odd that the ethernet cable died at the same time the battery bit the dust.

    Can't find a Toshiba OEM replacement battery


    So I decided to go ahead and buy a genuine OEM battery for this Toshiba L55T-C5290 notebook. The free utility BatteryMon reports the manufacturer as Samsung SDI model PA5185U-1BRS. But I'll be darned if I can find any model PA5185U-1BRS battery being listed anywhere as genuine Toshiba OEM, or having Samsung SDI cells.

    The 'Battery Replacement' section on Toshiba's 'Repair & Parts' page only takes you to a search for Toshiba service providers by state. I can't find any listed there that sell replacement batteries. I see Newegg lists 4 Samsung SDI Li-ion cells for the PA5185U-1BRS sold by Dr. Battery.

    After well over and hour of searching now, I've about given up trying to find a source for one of these. Has anyone here found any reliable sources for OEM or OEM equivilant quailty Toshiba battery replacements online?

    Are they all from China?



    The 1st looks convincing enough from that page, and from their Perris CA warehouse address NavyLCDR. But when you scroll down their contact info, it shows their office address as being in Shenzhen China. They've even misspelled 'Contact' as 'Cotact' in their URL and 3 places on the page it pulls up.

    I've Googled various combinations of the terms Genuine OEM Toshiba PA5185U-1BRS SDI Battery, and gotten several results on Ebay, Amazon, Newegg among others with prices ranging from ~$20 to ~$60+. When I check the supplier's address I don't think I've found one yet that isn't in China, and it seems most in Shenzhen. The Ebay seller 'acuder' on your 2nd link is also based in China.

    Copying "New Genuine Toshiba Satellite L55T-C5288 L55T-C5290 Battery" directly from the page your 1st URL pulls up into Google, it returns a nearly identically formatted website, reliablelaptopparts.com selling the PA5185U-1BRS for $5 less at $44.95. They're also based in Shenzhen China.

    The replacement notebook battery business has been turning into a ripe venue for scams in the past 10 - 15 years. I got ripped off locally by a company rebuilding them back in 2005. At this point I'm even wondering how much trust to put into reviews and recommendations.

    And I still haven't found any listed as being built with those OEM Samsung SDI Li-ion cells.

    Examine your current battery closely. Where was it made?

    I had to snap a few pix with the camera set to macro and blow them up big enough to read. The specs read:

    Toshiba Rechargrable Li-ion Battery Pack
    Model NO. PA5185U-1BRS
    DC 14.8V/14.8V - 45Wh/2800mAh
    Cell made in Korea Pack processed in China.

    So I guess I should send each seller a message asking if their batteries meet those specs including Samsung SDI cells. I don't think batteries made with cells with the same specs, but made by a different manufacturer are necessarily going to charge and discharge at the same rates, or have the same recharge cycles/life.

    Edit: Then there's the issue of what company designed the battery's circuitry. I'm looking at one on Amazon selling for only $16.97 that seems to meet the OEM specs, but is there such a thing as OEM circuit specs? $16.97 seems too good to be 'true'.

    Since your original factory battery was made in Korea and "processed" in China, then I would not think that the fact that a chinese company is ultimately behind whatever battery is on the market would indicate that it is not genuine "Toshiba." I put "Toshiba" in quotes, because even in the factory Toshiba brand computer, they may not be the actually manufacturer of every part in the computer.

    Well since it appears that Toshiba is no longer manufacturing and selling a battery for my L55T-C5290 notebook with parts made by them and / or companies they've contracted, it seems pretty disingenuous for any 3rd party manufacturer to label their 3rd party replacements as a Genuine OEM Toshiba battery.

    I'm more inclined to trust batteries sold by 3rd party manufacturers like Dr Battery that state their products are made to meet and / or exceed original OEM specs, and can show a long record over time of producing quality products. I wrote the Amazon seller offering that one for $16.97 and specifically asked if it was made with Samsung SDI cells. But the reply only parroted exactly what was written on the OEM label: "Cell made in Korea Pack processed in China." Just because battery cells are made in Korea, it doesn't mean they're going to be Samsung SDI cells, or match the OEM specs There are a host of Li-ion cell manufacturers in Korea, and the quality of each is going to vary.

    And like optical media, USB flash drives, and other digital devices, manufacturers are constantly making newer versions of their products that don't match the quality of their older products one way or the other. I had to search out feedback on USB 3.0 flash drives that where confirmed to operate faster than then average old 2.0 drives. That, after I popped for a 3.0 drive that was the slowest flash drive I've ever owned.

    This being such a specific battery compatible only with a small handful of Toshiba notebooks, it looks like it's going to be a challenge finding a replacement that performs like the OEM one. Mine would play video for 2.5 to 3 hours. I've read many, many complaints from buyers on Amazon that replacements for this PA5185U-1BRS powered their notebooks for just under or just over an hour.
