Keeppower 2 Pcs Flat Top 18350 10A Discharge IMR 1200mAh 3.7V UH1835P Quality High Drain Li-ion Rechargeable Lithium Battery

I needed this to replace a vape battery. I couldn't get a connection. Thankfully as a bonus they added a small magnet top if needed that can be attached to the battery. Proce was good too! It and the batteries work!

These batteries are exactly what they say they are! High drain 18350 batteries. I bought them for use in my LEP flashlights such as Lumintop Thor! The best part of these batteries are that they are flat top batteries but they include magnetic button top attachments that easily transform them to button top in an instant!

Powerful little batteries. Highly recommend.

I Purchased this February 2022, and I am writing this review 24 months later. At this point in time both batteries have stopped working. Both of them were placed into a rotation cycle along with two other 18350 batteries. The other two, both from modlite, are still currently working. Keeppower battery #1 died about six months ago, and keeppower battery #2 died about one month ago. Both of them appear to have sustained damage to the positive end of the battery. Possibly from recoil during use in my PL350 light. None of my other 18350 or 18650 batteries have displayed this weird pattern. While they were in use, I noticed no issues with performance or the batteries developing a “memory.” I did not notice any diminishing output or reduced performance prior to them ceasing to work. The two smart battery chargers that I have will not even recognize the battery when placed on the charger.

Great high drain batteries for my Surefire duel fuel handheld.

I bought these to replace the battery (900mah) for a Davinci vaporizer. These are a definite upgrade from the OEM. An extra 15-20 minutes of relaxation is well worth the switch.

I got these as an upgrade to the batteries that came in my laser (16340's rated at 700mAh). They came with small neodymium magnets to use if you need "button top" batteries, which I did, so thankfully they were included. Charged right up in my EBL charger. My laser works great! 5 stars.

**UPDATE 11/15/2022** Voltage still deteriorates at different rates between my KeepPower batteries during use. Caparatively, when using my stock Carta batteries in ly Carta V until 2 of 4 Battery LEDs show then I take out them out and both are at 3.67 to 3.69 volts for recharge. They're extremely like that when inserted into my charger that shows the voltages. These KeepPower batteries will still be upwards of 0.20 volts mismatched. 3.53 and 3.76 volts for example is not Keeping Power the same. Something isn't right to me but at least they're still working. I just like the voltage to synchronize when I marry 2 batteries into permanent pairs like they always have with other Bigger, more expensive brand name high discharge batteries. I'll live with it and I'll leave the 3 stars for average because it is good I can still use them. Not as much as years ago since the US Government 'Elected' representatives are representing tech Companies that fill their pockets by over regulating the fuel companies our economy still needs to run. Now I have to make all sorts of cut backs on everything from the harsh, stressful economic fallout of the Elected's deeper debt spending, sadly including activities that use these batteries. So I could never afford replacement batteries right now or for a very long time so these have to keep lasting like they have been. I'm sorry I'm stressed but felt I should update a year later since I said I would. Thank you for your time with my thoughts. Take care. ****UPDATE 6/8/2021**** Reached out to manuf. about deteriorating voltage loss of 1 of pair. Manuf. is sending replacement set, so I am giving 3 stars because of service department response and actions alone. Will follow up about replacement set performance. ****ORIGINAL STATEMENT**** Upon receiving these batteries everything seemed fine. I have a Nitecore 4bay charger that tells me the voltage remaining etc. These batteries were voltage matched upon first use. However within a coue weeks one battery drains significantly faster than the other. I like to charge 3.7v batteries when they get down to 3.7v. Over time 1 battery is gradually having a lower and lower remaining charge compared to the other. Now when I place them on the charger when it's time to charge, 1 battery will be at 3.55v while the other is at 3.78v. My other 3.7v batteries drain equally in the same device. So either the 1 defective or never was truly a 1200mah battery and is actually a 900mah or worse with a different wrap. Not happy. My stock batteries that came with my Carta V still deplete equally albeit a little faster due to aging. Hope this helps others.

Works great for my Radiomaster Zorro, it's very tight fit, they won't fall out if I drop the controller. Haven't tested how much run time I get with these high capacity (1600mah) cells. I'll update my review if the performance is lackluster, but 5 stars for now.

You would think they'd be close to half the price of 18650 batteries, but what do I know.

Excellent battery life in my Line 6 wireless transmitter. Had to modify case to accept the new battery but relatively easy mod

batteries work very well. Ideal replacement for NiCad batteries used in cordless screw drivers. Have to buy a compatible 3.7v charger which I got off Amazon. Replaced batteries in a Skil and MasaterCraft screwdriver.

I got 1172mAh in one cell and 1165mAh in the other. Very close to rated capacity on just the first charge test cycle on my Opus BT-C3100. Note you will have to condition the batteries with at least 5-10 charge/discharge cycles to get the max out of them. Comes in a nice plastic carrying case which is a nice touch. Note on the box it say "New" then the serial numbers so perhaps they changed suppliers and these are better cells than some people were experiencing.
