XTAR AA Lithium 4100mWh/2450mAh USB-C Battery with Low Voltage Indicator

I bought four of these for my external flash units and Godox triggers. The 1.5V 2A stable power output makes a huge difference in recycle time – my shots are consistent and fast, no lag between bursts. Compared to my old NiMH batteries that would drop voltage as they drain, these lithium ones maintain full power until the very end. The 1200-cycle rating means I won't have to replace them for years. Absolutely worth the $24.99 price tag.

Kids' toys eat batteries like candy. I was spending a fortune on Duracells every month. These XTAR rechargeables have cut my battery budget by 90%. The 1200-cycle durability means I'll probably pass these down to my grandkids (joking, but seriously they last forever). The USB-C charging is so simple even my 10-year-old can plug them in. And the safety protections give me peace of mind with the kids around. A total game-changer for any parent.

Finally, a rechargeable AA that doesn't suck. The 4100mWh energy density is seriously impressive – that's more than double what most rechargeable AAs offer. I've tested the cycle life and after 50 charges it's still performing like day one. The USB-C port is recessed nicely so it doesn't protrude, and the included 4-way splitter cable is a thoughtful addition. The only downside? I wish I'd found these sooner. 5 stars, no hesitation.

I manage a small office with 12 employees and we go through AA batteries like water – wireless keyboards, mice, and presentation remotes. Switching to XTAR has been a revelation. The fast charge means I can rotate batteries and always have a charged set ready. The 2A output keeps all our wireless devices responsive. And at 1200 cycles per battery, the ROI is incredible. My boss actually complimented me on the cost savings. These are now standard issue in our office supply closet.

Between baby monitors, thermometers, and various kid gadgets, our house runs on AA batteries. These XTAR rechargeables have been a sanity-saver. The USB-C charging means I can use the same cables I already have for our phones and tablets – no more hunting for proprietary chargers. The 2.7 hour fast charge is perfect for our chaotic schedule; I can charge a set while making dinner and they're ready by bedtime. And the safety protections are a huge plus with little ones around. Absolutely love these.

This is my first time to purchase XTAR products, and I was strongly recommended by a friend. The battery has been in use for over a month and there are no problems so far. The battery capacity is excellent and the charging method is very convenient. There is no need to purchase an additional charger. 10/10

Easy to use. Long battery life before recharge. Nice touch with indicator light.

I've been using these XTAR AA lithium batteries in my wireless computer mouse and TV remote for about two weeks now. The 4100mWh capacity is no joke – my mouse used to eat through alkalines every 10 days, but this one is still going strong at 80%. The USB-C charging is incredibly convenient; I just plug it into my laptop charger for 2.7 hours and it's full again. The low voltage indicator is a lifesaver – no more sudden shutdowns during important meetings. Highly recommended for anyone tired of buying disposable batteries!

The low voltage indicator is genius. I travel a lot for work and carry my presentation clicker and noise-canceling headphones everywhere. With normal batteries I never knew when they'd die mid-presentation. Now I just glance at the indicator light and know exactly when to charge. 2.7 hours fast charging means I can top it up during a coffee break and be good for another week. This battery has literally saved me from embarrassment twice already.

The low voltage indicator should be giving me signals on low battery far far sooner than it does. I use these in VR headset controllers and I get maybe a 20 second max warning before they actually die.
Otherwise, these batteries last a very long time. Quick charging time. Same size as a standard AA battery. Love that they're USB-C rechargeable.

The reason I'm taking off two stars is 1. The low voltage indicator being a very short time. 2. The reason I paid the higher price was for the low voltage indicator, but since the indicator doesn't let me know until it pretty much dies, I'm knocking another star off for price.

I use these in my Xbox controller and they last forever. The 2450mAh capacity is perfect for long gaming sessions – I get about 25-30 hours of playtime per charge, which is insane compared to the 8-10 hours I got from Eneloops. The 1.5V constant voltage means my controller never lags or disconnects even when the battery is low. Best gaming investment I've made this year. Already ordered another 4-pack.

I test camping gear for a living and these batteries have become my go-to for headlamps and GPS devices. The stable 1.5V output ensures my headlamp doesn't dim halfway through a night hike. Recharge time is impressive – 2.7 hours and I'm back to full capacity. The low voltage indicator is particularly useful in the field; I can check remaining power at a glance without carrying a multimeter. These are built to last, and the multiple protections mean I don't worry about them in extreme conditions.

I have an automatic pet feeder that runs on 4 AA batteries. Before XTAR, I was replacing alkalines every 2 weeks. Now I'm on week 8 with the same set of XTAR batteries and they're still showing green on the indicator. The 1.5V constant power means the feeder mechanism works smoothly every time – no more jammed food dispensing. And the peace of mind knowing my cats won't miss a meal because of dead batteries? Priceless. Best pet-related purchase I've made.

I use these in my digital calipers, laser level, and stud finder. The consistent 1.5V output is crucial for accurate measurements – unlike alkalines that drop voltage as they deplete and throw off readings. The 4100mWh capacity means I'm not constantly swapping batteries mid-project. The low voltage indicator is perfect for telling me when to recharge before the next job. These have become an essential part of my toolbox. If you do any kind of precision work, you need these.

I use these AA batteries in my drone remote controller and FPV goggles. The 2A high-current output ensures my controller has zero latency, which is critical when you're flying FPV at 80mph. The 1200-cycle rating means I'm not constantly buying new batteries, and the multiple protections give me confidence that I won't have a battery failure mid-flight. The low voltage indicator is a nice touch – I can quickly check power levels before heading out to the field. These are now the only AA batteries I use.

Working from home means my wireless headset and keyboard are in constant use. These XTAR batteries have been a revelation – I used to change batteries every 10 days, now I'm at 3 weeks and still going. The USB-C charging is seamless; I just plug them into my laptop dock and they're charged in no time. The low voltage indicator is so useful – I can plan my charges rather than being caught off guard. These have genuinely improved my productivity. 10/10 would recommend.

As a college student, I rely on my wireless mouse and calculator for exams and daily work. These XTAR batteries have been a total game-changer. The 2450mAh capacity lasted me through an entire semester of daily use – that's over 4 months! The fast charge means I can top them up during a study break. And the price is totally reasonable for what you get. My roommate was so impressed he bought a set too. Highly recommend for any student on a budget.

I use these in my hearing aid battery charger and digital blood pressure monitor. The stable power output gives me accurate readings every time – no more fluctuations caused by dying batteries. The 1200-cycle durability means I won't have to think about batteries for a very long time, which is great at my age. The low voltage indicator is easy to see even with my aging eyes. And the safety protections give me confidence using them around the house. A wonderful product that makes daily life easier.

Ich benutze diese XTAR AA-Batterien in meiner Küchenwaage und meinem Funk-Thermometer. Die 4100mWh Kapazität ist beeindruckend – meine Waage läuft jetzt seit über zwei Monaten ohne Probleme. Das USB-C-Laden ist super praktisch, ich kann einfach das gleiche Kabel wie für mein Handy verwenden. Der Spannungsanzeiger ist sehr nützlich, ich sehe sofort, wann nachgeladen werden muss. Nach 20 Ladezyklen funktionieren sie immer noch wie am ersten Tag. Absolut empfehlenswert für alle, die zuverlässige Akkus suchen.

J'utilise ces piles XTAR dans ma souris sans fil et mon clavier depuis trois mois maintenant. La capacité de 4100mWh est vraiment impressionnante – je n'ai rechargé qu'une seule fois depuis que je les ai achetées. Le chargement USB-C est tellement pratique, je peux les brancher sur n'importe quel chargeur. L'indicateur de basse tension m'évite les mauvaises surprises pendant mon travail. La charge rapide en 2,7 heures est parfaite pour mon rythme de vie. Je recommande vivement ces piles à tous mes collègues！

He estado usando estas baterías XTAR en mi control de Xbox y mi mouse gaming por más de un mes. La capacidad de 2450mAh es increíble – juego unas 20 horas a la semana y solo he tenido que cargarlas dos veces. El indicador de bajo voltaje es súper útil, siempre sé cuándo es momento de recargar. La carga USB-C es rápida y conveniente, y las 1200 recargas garantizadas significan que no tendré que comprar baterías por años. ¡Una compra excelente！

Compré un paquete de estas baterías XTAR para los juguetes de mis hijos y los mandos a distancia de la casa. Ha sido la mejor decisión. La capacidad es tan alta que no recuerdo cuándo fue la última vez que las cargué. El indicador de bajo voltaje me avisa con tiempo, así que nunca me quedo sin batería en medio de una película. El cargador USB-C es muy práctico, uso el mismo cable que para mi teléfono. Mis hijos ya saben cómo ponerlas a cargar solos. ¡Fantástico！
