    I've been looking for a battery for my 2013 for a while now, so I decided to try this. The battery looks identical to the battery that came with the laptop (even has "Betty" on it). Installation was easy outside needing to find a tiny star bit to unscrew the back cover. However, I'm having mixed results as far as performance goes. One of the first few times I tried discharging it I got about the amount of battery life I was expecting (~3 hours of moderate to heavy use). However, now the battery meter in Windows is behaving really strangely. I can't say whether it's the battery or something else, but when I unplug the AC adapter, the meter sits at 100% for a while. Eventually it will suddenly drop to 50% or so, and then I get maybe 30 minutes from there before the laptop turns off. It must be a calibration issue of some sort, because I don't think the battery is fully charging either (no charging when it's stuck at "100%"). I'm using some 3rd party power tools to get an idea of what's going on now, so I'll report back if I find anything. Razer unfortunately still seems like the best option for a replacement battery. Just wish they would sell the part instead of requiring the laptop to be sent in for service.

    No luck with that replacement battery unfortunately. When monitoring with BatteryBar, it will claim to charge to 27,000 mWh, then suddenly shut down after only 5 minutes of use, then claim to have a capacity of 7,000 mWh instead. Then I can hibernate the laptop for a day, and suddenly the capacity is 22,000 mWh. Requested a replacement from the vendor, hopefully the next one works better.

    Any luck on a replacement? I am looking to go this route if it is possible. Pretty tired of waiting for Razer's reply/I can only imagine their prices...

    The replacement didn't do much unfortunately. It would get to around 70%, then start discharging. If you left the laptop on, it would eventually discharge itself to zero. I swapped back to the original battery and stay mostly plugged in now (ordered a couple aftermarket power supplies after the original failed).

    I was considering getting a new Blade, but instead recently placed an order for an Aero 14. I have a lot of Razer products, but I'm not quite satisfied with their cost vs quality on the Blade.

    Interesting behavior you described here.


    Basics about the battery:
    Li-ion till 2015, Li-po from 2015. It seems to have stayed the same except that.

    The battery is named "Betty" has 6400mAh and is 11.1V.
    It is an arrangement of 6 cells with assumably 3200mAh each.
    Cell Label: SL426399
    The charging part is integrated into the battery and is connect over an SPI Bus Slave with the system.
    Balances the cells.

    The Main controller that actually decides if it charges is the "Texas Instruments BQ25A" actually TI BQ24724A.
    http://www.ti.com/lit/ds/symlink/bq24725a.pdf
    Also an SPI bus device.
    That bugger regulates the chraging- voltage that is supplyed to the battery.


    I havent jet taken apart the bettery that much that i can tell what controller is inside of that but there is a "Learn" state that is for learning the battery capabiletys.
    Maybe that is worth a look.




    Every shop i found that carrys these interestingly has the same pictures and that looks a bit scammy.

    This is the best i have found so far is this.
    https://www.aliexpress.com/item/Lap...el&btsid=73c566b4-9f8d-4652-97db-9b370b8a001e

    EDIT1:
    The in battery pack IC is a Texas Instruments ti bq20Z75.
    Maybe the Datasheets on those can tell interesting storys.

    In case that one of you has bought one of thouse replacements, and is disapointed, i'd like to take a look at that bettery!

    Thanks
    Sincerely Rage

    Hey,

    So after months (years!) of gradual degradation, my battery finally kicked it yesterday - it holds zero charge. More annoyingly, the machine would randomly power off when the battery ran out of juice - even when plugged in.

    Luckily I had already read about this behavior previously and know that it can be solved by simply disconnecting the battery, which I did today (note, you need a Torx T5 screwdriver to open up the case). There is basically a problem with the charging circuit, where it will continue to try and draw power from a dead battery (rather than the AC adapter), even when the battery is dead.

    So now my venerable 2013 Blade is but a glorified desktop... I don't suppose anyone has managed to source a reliable replacement battery? I refuse to send my machine back to Razer (rip off + hassle of not having a machine for days/weeks).

    Thanks,

    Su

    Ahh yes, the charge circuitry issues.....To help identify this please tell me, with the battery plugged in and AC adapter plugged in, does it stay at near 0% battery or possibly 1-2% and then just randomly shutoff after a few minutes with the adapter plugged in? If so, that is due to motherboard issues and not the battery. I do have many options for you there, either repair, or even replacement motherboards which i could ship to you(currently have 1 left for your model, so let me know). As for the actual battery itself, it's possible it is going bad as well but from what you described it sounds to be just typical charge circuitry issues on the main board.

    Hi,

    Has anyone tried any of the replacement batteries available on Amazon? Seem to be from a bunch of random no-name companies... (click for links):

    Antiee

    ZTHY

    Litu

    Sunnear

    There may be others kicking around as well, but these are the first few that I found. Interested to hear if anyone has any experience with these brands!

    Cheers,

    Su
