HFR-50AAJY1900x2(B) Battery Compatible with nvidia Shield Game Controller 1800mAh/4.32Wh

Battery instalation was super easy. I initially had issues when it came to charging the new battery. It would begin charging.. then disconnect.. then connect.. constantly. After reading the product description again, and noticing all the built in safety features, I assumed the micro usb cord I was using was cheap. Grabbed a better made cord and it charges without issue! The designer of this battery is preventing you from ruining another battery lol, so charge it the right way and you're golden!

Installed in my shield controller. It has less than a week storage life without being used. Should last much longer. Maybe I got a dud. UPDATE I disconnected the controller from shield and recharged the battery. It is holding a charge just fine. I'm guessing there is an issue with the controller which slowly drains the battery when connected as an accessory to shield. I have changed my rating as a result

Worked literally once. Has been charging for days now... still at low Update #2: still charging... still at low

**Update** I exchanged the battery and the replacement battery works well. I'm happy with this product now. **Original Review** The battery won't fully charge and it dies really fast.

very easy to install, fits prefect in the case. only thing is I had to modify the space that it goes in. but that is nothing that cant be done in a few seconds. but battery itself comes charged and charge last a long time. i will say that it goes about a week on all the time until needs to charge. keep in mind that if you don secure it wit double sided tape it will rattle inside the controller. plug fits snug and secure as well.

Took my Nivida Shield controller apart by watching YouTube video and switched out battery, like new now.

I purchased this going in blind. I have had a problem with my original shield batteries going dead and not being able to charge. I had looked around and the seller that is making these has done an amazing job this has fixed my shield controller it is working like new the battery fits very easily to put together. The hardest part is taking the controller apart without damaging and reassembling is equally as difficult.Make your purchase with confidence this is the correct battery to repair your dead Nivida Sheild battery.

So...like...once upon a time...there was a nvidia shield I've had forever....and um...like...the battery totally was acting super lame...like...omg....it wouldn't HD a charge...and the shield was always like...your battery is hella low...so...I was like...youtube...give me a sign....and it totally was like...get this battery and a little t6 screwdriver and you can fix this at home like a superstar...so like...omg...I totally did it...and feel like one of those really cool guys who works in the little booth at the mall and can fix your phone. Yay! BATTERY!! You can do it too. And when you're done go...YAY!!! Or Woo!!! Like 16x World Champion Rick Flair.

Take your time when swapping these out, but this was a perfect replacement. After about 15mins (I took my time after the internals moved around on me and I had to piece together again) then charged the battery up. Worked perfectly. Really happy with the replacement.

still going a year later

It was good while it was full, The moment it got empty, I couldn't charge it even one time. It stays empty

This does work as a compatible replacement for the Shield controller battery... but the self discharge rate is way too high for a quality NiMH cell. Two weeks idle (zero use) and the battery goes DEAD.

Works well
