Rechargeable Battery Pack for Xbox, Fast Charging Station for Xbox Series X/S/One/One S/X/Elite Controller Batteries, Xbox Battery Pack with Charger (black)

My credentials:I studied Electrical Engineering in college and got my BS and MS degree in it, I also did some DEEP research into how battery technology works, so I have a fair idea of what I'm talking about.This product: It's great.Why? You can charged it in 3 different conventional ways, plug-in to a USB charger, Plug in a Micro-USB, & plug in a USB-C.Another Why? The battery works well. Full 12 hr sessions of constant use.Maintenance: I'd say about once every 2 weeks just charge it up for 24 hrs and remove it. That should help keep it from exploding. Keep it alway from heat.Explaination: Because of how ALL NiMH (and Lithium) batteries work, do NOT keep it charging nor fully discharged for a prolong period of time. When a battery is 100% (~4.2V) or 0% (3 V) is when the anode and cathode (the +/- sides inside the batteries) are at their closest. Nintendo recommended their Switch would be charged once every 3 month. I'd say 2 weeks just in case. Also heat causes the battery to expand and contract, which could cause internal damage. I lost most of my rechargeable devices from not charging it for a long time (all batteries leak charge until they hit BEYOND 0% and the anode and cathod touch each other internally and Boom, battery pops and battery acid everywhere.More updates soon...If you lose these batteries in any way, just get these: DURNLAA4BCD - Rechargeable StayCharged NiMH Batteries https://a.co/d/8hg5QHuThese green skin NiMH batteries from duracell, sold by duracell, made in Japan, are well tested for durability, and accuracy to the specs. Tested by project farm on youtube.*Important note*Oh, from what I see, these chargers are not the best when it comes to cleaning the power. This is my setup, I have a UPS on my outlet (CyberPower ST425 Standby UPS System, 425VA/260W, 8 Outlets, Compact, Black https://a.co/d/c7NlCtl) and have that hooked up to the surge protector side is (Fast Charger, Sacrack 100W GaN Compact 6 Port Charging Station, Portable Wall Charger Adapter 3 USB C and 3 QC USB A for All iPad iPhone 14 13 12 11 Pro Max Pixel Note Galaxy https://a.co/d/hRoJZ6m)Outlet -> UPS -> 100W Charger -> this battery charger -> this battery.So the power I supply to these battery is VERY clean. BECAREFUL of unclean power source. Don't hook it up to your outlet using a cheap charger. Cities have power fluctuations all the time, sometimes the outlet could be faulty, sometimes your house is not wired right. I'm an Electrical Engineer being as careful as an electrical engineer should.

The batteries I had weren’t stay charged long enough so he suggested to replace to replace them and the charger ,I looked around and sent him many pics of different products til this one was sent and I received a thumbs 👍🏽.This pack consists of a charger kit and 4 batteries for a very good price. I play at least 1 NBA2k game a day and binge watch on my tv the whole week and since my purchase of over 2 weeks , I have only charged the battery.

4 stars. They never show a full charge on the xbox home screen but they work cery good. They charge pretty quick and there are 4 batteries total. Great buy for the price

This what a great purchase

They last for a very long time in between changes.And save you money on batteries I have 3 and we haven’t bought batteries for our controllers in ages.

Purchased two years ago for my boys Xbox controllers. They have pretty good battery life and quick recharge. They last about 8-10 hours.

Ya llevo más de un año con ellos y 0 problemas.

The description says in multiple place that you get 4 batteries. We only received 2 batteries. The box has room for 2 more batteries. Going to try a replacement for missing items. Will update when replacement comes.
