Y26650A Rechargeable Battery Flat Top 3.7v Rechargeable Battery for Flashlights and Headlamps

I had been using the smaller battery size but similar to these, not knowing these existed. This fits my flashlight perfectly when you remove the spacer adapter for the 18mm battery. They don't appear to be any brighter than the other batteries but the run time is really long, maybe 50% more run time. The batteries feel well made with consistent good quality material. I've noticed that these seem to hold a charge in storage better than my ageing 18mm batteries did.

I ordered these Yuntunele Y26650A Li-Ion batteries for my LED flashlight. It requires 26650 cells. Even though they are only rated at 5000mAh each, lower than my current 7000mAh cells, I chose them because they showed these are manufactured in Japan. That was one of my priorities in selecting these cells among many others out there. And the price reflected that being more expensive than average.When they were delivered, I was immediately taken aback when I read the box they arrived in stated Made in China. And inspecting the cells, although they look like the ones described in photos, the Made in Japan label is nowhere to be found. These are not Japanese made 26650 batteries.This is blatantly misleading, as had I known I would have chosen far less expensive Chinese-made cells like my 7000mAh rated units. I would have paid less than half the cost of these.Do these work? Probably, but that's not the point. Bait and switched leaves a bad taste in your mouth after spending your money on something that didn't meet expectations or description actually! Not a good business philosophy going forward. I'm disappointed!UPDATE:They don't seem to last as long as my previous 26650 cells, or even my 18650 cells! Avoid these!

First, the picture clearly shows "Made In Japan" - that was a lie.Second, the 5000mAh rating is laughable. I got 2950mAh.Get these only if you really, really need a 26650 cell and cannot find it anyplace else.Two stars because they do actually store a charge.

I have a lot of flashlights. Only one of them uses 26650 batteries so I got this set.They come in a decent plastic case and are wrapped in plastic wrap to protect the contacts.5000mah? Nope. My tester revealed only 3700mah on both. Good but not what they claim.That said the, batteries came 70% charged and topped off in 20 minutes at a 2 amp charge.26650 batteries are getting hard ti find in the USA so I was pleased to find these.Overall, I think the batteries are a decent deal and pretty good quality. I like them.

These are exactly what I needed. These are NOT the standard 18650 cells people are used to. My pics I show a standard one for comparison. these will not fit in placed intended for 18650's only. But some of my flashlights are oversized and these fit perfectly and give me almost 2x the capacity. IF your device had the design to fit batteries of this shape its an easy upgrade from the 18650 profile

Arrive in a plain brown box with a Made in China sticker on it. No branding anywhereBatteries are in a Ok quality plastic case not mentioned in the description for a nice surpriseNeither battery lists the country of origin let alone any brandingBatteries weigh 77.9g and 76.6g, which is a bit light for this size cellBoth were at 3.96VThe listing photo claims these are Made in Japan. What arrived was Made in China according to the boxThe listing claims 5,000mAh capacity. I tested both and NEITHER get to HALF that capacity (2,195; 2,233)Misleading on the country of origin. Completely incorrect capacity specsYou are better off buying a good 18650 cell and using a sleeve spacer

Don't bother with these batteries - their actual capacity is less than half the advertised 5000 mAh. I measured it at a bit over 2100 mAh. I got these for flashlights but I could have gotten the same capacity from a smaller decent-quality 18650 cell.

These batteries are perfect or exact replacements for my rechargeable flashlights. These can be handy for camping, to have extra power available. The flashlight can also be used as a power bank, so it's like having one power bank now with extra swappable internal batteries. Having these extra batteries is also way better than using AAA alkaline batteries as backups, which require an internal adapter. My flashlights are model A05 from brand AHHZDZQ, but there are a lot of rechargeable flashlights that use this battery.
