2-Pack SNSYIY 3.7V 3600MAh USB Rechargeable Button Top Batteries For Klarus Flashlight (XT11X, XT11GT, XT30R.) Review

These are 3.7V 3600mAh rechargeable lithium batteries that can be charged with micro-USB cable.It came in 2 packs inside a plastic storage case that fits both perfectly and while it didn't come with micro-USB cable, people have plenty of micro-USB cables laying around these days so it's not a problem at all.It's cool that it has micro-USB port on top of the battery so you can simply plugin the cable and recharge these batteries using any standard USB powered port. I have few flashlights that…

I have a MacBook Pro that is 10 years old, and I had not been using it much because it needed a new battery. I knew it would probably be an expensive fix, if I took it to the Apple Store. So it sat collecting dust for a couple of years. I decided to check on the cost of a battery, and quickly found the one I needed on amazon. The battery comes with clear instructions on how to change the battery out, and even has the screwdriver needed for the specialized screws. I sat down and started taking…

I love my new batteries, but the customer service is even better.I had defective batteries in my order. The sellers quickly shipped replacement batteries. Once they shipped, they consistently followed up to ensure I received the replacements. Upon confirmation of the receipt of the replacement, they then ensured the new batteries worked as expected. Accidents happen, but they went above and beyond and provided amazing customer service.

Bought these batteries for my friend, who owns a Fenix HL60R headlamp. He told me they fit and work well despite being a little bit bigger.So I decided to buy a pair for the same headlamp and now I have a good amount of spare batteries for hunting trips.

These batteries are larger in size than the original. I had to force the battery into the flashlight. It cannot be extracted. I tried to contact Klarus via email. No response ! No help from revain. When the battery goes bad I will have to throw away the flashlight!

First of all, the voltage of the battery is very high, it is very durable, and it has a very convenient socket, and I like the design of the indicator light, which allows me to easily identify the battery level. Because of this high voltage, the flashlight becomes very bright. However, the battery with its own charging socket also has a disadvantage, that is, the length is a little longer than the ordinary 18650 battery, but this does not affect the use. In the end I think that if you are using

Just a heads up, if you have a Zebralight using 18650 battery, this product will not fit. If you stupidly jam it in like I did, your flashlight is useless (once the battery is spent), or you could try drilling out the base of the battery to get it out of the flash light -- not sure if this is a safe thing to attempt so I just trashed a $90 light. As other reviews have stated, it is longer and fatter than the "standard" 18650. One star because I cannot use it so I can't rate on any of its other…

I bought this to use as a spare in my fan. I went according to the size on my current battery. This one was much bigger so I couldn’t use it. Had to send it back. I’m sure the battery would have worked as intended had it fit. Something worth noting is that my original battery says 18650, 3.7V whereas this product says 18650, 3.6V. So that might be what makes the sizing difference.

This battery is a must have for replacing your flashlight battery. It easily charges with a type C charger and allows you to easily charge it with your charger if you have a phone that uses type C charger. It makes the flashlight super bright and allows you to see better. It's very durable and will allow you to have light for longer. Amazing price

I didn't notice at first, but when using these batteries in my ThruNite headlamp, the light would flicker and shortly thereafter shut off. Turning the light back on the light would stay on for three to five seconds and shut off.At first I thought the battery may have been low, but I didn't recall much burn time on that charge, perhaps 5 or 10 minutes NOT on the brightest setting but put the battery back on the charger. I cycled through the two batteries plus the OEM battery that came with the…

I was ordering these for an oxygen machine that had an 8 cell 18650 battery pack. These came up in a search for 18650s and they had the highest power rating, so I ordered thinking they would make the oxygen machine run a little longer on a charge. They even say 18650 on the side of each cell. But they are longer and larger round than an 18650. They have a micro USB port on one end to charge as well, which was a nice feature, even if it wasn't needed. I did find a use for these, and they work…

Great batteries, and USB charging option is handy.I tested these batteries for actual MAH value, as opposed to the value advertised.These batteries tested around 3100 to 3250MAH, which is fairly close to advertised MAH.These batteries are only slightly wider, but the length difference from negative end to button top, compared to non-USB port button top batteries, is reasonably substantial. If your device's battery compartments are spring loaded, or even slightly longer than typical, these…

I have multiple flashlights that use 2 CR123 batteries. These are an excellent option. They last longer and are easily rechargeable. FYI, if used like any other rechargeable battery, when they are almost dead, it will take over night to complete the recharge.

These batteries work great in my flashlights. Much brighter and last a LONG time. Super easy to recharge too with the Micro USB port that's built in. They are a little longer than a standard 18650, so keep that in mind when purchasing.

I brought a battery witch clearly says its for my flashlight 🔦 now the battery was a little hard to push in I thought maybe because it's new so I pushed it in now my 100$ flashlight is gonna

this 18650 rechargeable battery stays longer than any battery of this type and the are expensive but worth the price. That's my review.

I bought a couple of these to replace the worn out batteries in my flashlights, they've worked out great. 200 more MaH than what the flashlights came with, and the usb charging port seems like it would be handy if I ever mess up the charging port on the flashlight itself.

I ordered these as backups for my Fenix HM650R headlamp. I liked the idea of being able to charge the batteries in my truck without needing a separate charger. I realized they might be a bit longer than a standard 18650 due to the inclusion of the charging port, but most reviewers said their flashlights would accommodate the additional length, so I decided to give these a try.As I was test fitting one into the headlamp, I noticed the fit was extremely snug in the tube - I was still focused on…

After about a year, my Ring pathlights stopped working. After making sure that the wifi was working and that the Ring bridge was still functioning, I figure that the battery was dead. However, Ring doesn't sell replacement rechargeable batteries for their pathlights. I assume that they figure people can just buy another pathlight.These 3.7V Button Top Batteries USB Rechargeable Battery 3600mAh fit the pathlights. These batteries aren't cheap, but they are still less than half the price to…

Batteries are really very reliable, for the work of devices is just perfect! And when all the same the order came was very surprised by the work of these batteries.Good quality product at a great price I am very satisfied Thank you
