Futurebatt A1331 Battery for Apple MacBook Unibody 13" A1342 Late 2009 / Mid 2010

Perfect. No issues with the battery.

I had an old 2012 asus laptop. It was stored away only months after purchasing due to a corrupted os and proprietary software. I recently fixed that part by installing linux mint replacing windows etc. The only thing left to replace was the battery. This worked out well for me and i now have a spare 'brought back to life' laptop. No issues whatsoever and it took a bit less than 30 minutes to fully charge. It feels nice to have saved a pc from the trash or recycle pile!

I’ve personally installed so many of these batteries in the past, and wasn’t really feeling like doing this one too on a machine that’s 11-years old. However, I wanted to play some old 32-bit Steam games on an older MacOS, so here we are. This battery arrived in a clean box, with all the tools necessary to do the task, except one important safety tool. With that, a word of caution to anyone reading. Make sure you’re installing this battery in a place where it’s static free with an ASD grounded strap attached. If you can’t do that and want to take the gamble anyway, understand you could fry your logic board if your body issues a shock to the computer. Basically, if the air is dry and everything you touch zaps you, don’t do this install. There are no static discharge tools that comes with this battery. That out of the way, I also recommend using an empty ice cube tray or something similar to sort your screws (so you won’t lose them). When I held both batteries, I was kind of shocked over how light this replacement was. Like, pretty alarmed wondering if I bought a defective unit. But nope. It went into my Mid-2010 White Unibody MacBook with ease. The cabling this new one comes with is a bit long compared to Apple’s. So you’ll have to carefully route all that cabling before reattaching the bottom plate. If you’ve read this review this far, here’s another tip: DO NOT PLUG IN YOUR CHARGER YET!!! With Lithium Ion batteries, it’s super important to set its memory. It came charged from the factory, with slight drainage during shipping and in storage. So it may only have a fraction of its total capacity. That said, keep its trajectory point towards 0%. From there, power on the MacBook. If no power, then plug it in to see if the battery is either not connected at all, defective, or just drained to 0% anyway. When powered on, let the computer drain. I recommend all the way. Want it drained faster? Fire up Chess and set CPU vs CPU while playing a movie in the background as well as Apple Music / iTunes with the visualizer on. When it dies, plug it back in and charge to 100%. I recommend doing this 2-3 times so your battery knows what empty and full capacity is. Otherwise you can train ‘any’ lithium-ion battery to think that 50% is 0% with a erratic charging behaviors. But I’ve had this battery for a month. No complaints yet. It’s drains slowly while playing “Witcher” (one of the games I wanted to play), and lasts a long while in the computer’s sleep state.

I bought this battery for my HP EliteBook 8530p on November 23, 2023, and used it for 2 years, and it is still going, even though the battery life and battery health have dropped a lot from when it was new. It is still worth the price.

I've only used it a little on my old laptop but it played a video over WiFi for 4 hours.

Bricked my laptop in spite of following replacement instructions down to the t (I've replaced batteries several times in the past, so I'm familiar with the precautions that need to be taken during a battery change) -- this is a cheap build, possibly a company that ships product with minimal quality control. In my case, I ended up bricking a $1300 macbook because the battery circuit was faulty to begin with. I recommend using other sellers/makes if you're looking for reliable products that won't fry your motherboard.

Apple is notorious for trying to keep people from upgrading or replacing their own hardware. Don't believe me? Look at modern macs that won't even let you replace the SSD. Crazy. This older macbook from the 2010-2011 era is an exception however, with really easy to access components. I've heard that some versions of mac osx are picky about the battery you install, as apple adds a chip to the battery to help manage power consumption. Whatever the reason, this battery doesn't have any issues. It has been installed in my sisters macbook over a month, took me 5 minutes to install (Seriously, all you need is a phillips screwdriver and 5 minutes). I got her the macbook second hand for $50, so I didn't want to spend a ton on a battery. That being said, I don't know what kind of battery life these things realistically got when new, but she's averaging 4-5 hours now. Pretty good! If you want to bring an old macbook back to life, this is a great choice. NOTE: It was clear the construction of the battery CASE was a bit flimsy. The plastic tabs holding it together weren't strong, and it was already splitting when I got it. I don't consider this an issue, and neither should you. The internal battery is high quality, and you'll never see the casing. This is a budget replacement item that goes inside a computer, so asthetics don't matter to me, and they shouldn't to you. That being said, I know apple tends to attract a, how do I say this.... "Picky" user. But theoretically those type of users upgraded to the newest macbook pro and ditched this thing long ago. Still worth noting. Enjoy! #PCMasterRace #AppleMakesMeCry

This battery does NOT fit A1708 Macbook Pro. The battery connector is thicker than OEM, the connector screw does not reach the bottom thread, it is short.
