RayHom AA Rechargeable Batteries 2800mAh Ni-MH Battery (16 Pack)

I have several sets of these in AA, AAA and C sizes, some of which I bought four years ago. I use these for various things but primarily use them for multiple Luminara candles. As an example, I have eight pillar candles staged on a multi-height stand in an unused brick fireplace. Each candle is powered by two of the AA size Ray Horn batteries and burns five hours every night. I change them for fresh ones once every four or five weeks, keyed on when a couple of the candles don't come on as scheduled. I have additional candles throughout the house operating in the same fashion, providing a subtle lighting solution throughout. Since the candles work both on a timer and via a remote control, handy when the power goes out. Out of about sixty candles, NONE have gone bad which I think is remarkable!

I just ordered 16 of these batteries. According to Tenergy, these batteries are rated at 2292 mAh. (6 hours to charge, from totally discharged to totally charged).I still like them, tho.A/ Even at 2292 mAh, they are priced right.B/ They are dependable. Out of 16 batteries, not one was defective. Try getting these results from some of these other manufacturers.C/ You get four nice battery cases. Try telling these other manufacturers that you expect to get four nice cases with your order. See how far you get with them.I took one star off for lying to us about the capacity of these batteries.Yes, they are made in China. I don't care if they were made in Zimbabwai, as long as the product is relieable, and they can save us money.

In the past 8 years, rechargeable batteries have become quite popular in the market. However, I’ve noticed that the chemistry in domestic rechargeable cells has remained the same. To sum everything up, the batteries act as voltaic systems with nickel metal hydride electrolytes across a semi-permeable ion barrier in between. To the average person, this may not make much sense, but what I’m trying to say is that all of these rechargeable batteries function similarly, and are designed similarly. Virtually the same chemicals are used to create them, and the processes used to manufacture the batteries are similar. However, some manufacturers take it a step further my slightly improving the designs of the electrolyte barrier in the batteries. As a result, a slight capacity increase is added to the battery. This also often means that more money is needed to manufacture the product.Let’s take a look at these aa batteries for instance and compare them to the other major battery manufacturer that starts with a “D”. The biggest capacity for those batteries is 2500 mAh. These, have a slight advantage coming in at 2800 mAh. Now both use the same chemicals inside, but like I explained previously, it comes down to small design changes that improve battery life, which Rayhom has done. Although this difference of 300 mAh may seem small, I am comparing the largest capacity in another manufacturer which I could find. This difference in capacity is a 12% increase, which is quite a lot if you think about it.Finally, at the time of purchase, I also compared the price differences between the 2500 mAh battery and these batteries. During this comparison, the major brand was on sale, and the price per battery turned out to be the same. Given this information, I might as well go for the higher capacity batteries whilst paying the same price. The quality is just as good, and they even come with great cases allowing me to not always misplace the batteries!

I condition all of my rechargeable batteries before use, and I use a Ambient Weather BC-3000, which is a less expensive version of the Opus BT-C3100 & BT-C3400 charger/analyzer. Although these batteries claim a fully charged rating of 2800mAh they only charge from 2225mAh to 2298mAh, but they do that pretty consistently. The good news is they have a good build quality and are cheap. I bought a 16 pack of these batteries for $21.97 making their cost $1.38 per battery. That is not bad for a 2200mAh battery. The price for the regular Panasonic Eneloop 16 pack is $37.39. That is $2.33 per battery for the 2100mAh eneloop. The AmazonBasics AA High-Capacity (rated at 2400mAh) 8 pack will cost you $18.99, which is $2.37 per battery. So for $1.38 per battery, the RayHom AA 2800mAh are the best value. If they had rated these batteries at 2300mAh instead of 2800mAh they would probably sell better. Also, all 16 of the batteries I received were good. All charged slightly over 2200mAh and a few charged to just under 2300mAh. You can check the 4 star ratings for the AmazonBasics AA High-Capacity and see a review where the actual rating for that battery is really 2300mAh, which is not bad either, but it is not a bargain. If you think you really need a higher capacity battery, you might check out the EBL 2800mAh battery. It holds a charge of 2666mAh to 2745mAh and a 16 pack of those will cost $28.96, bringing the price per battery to $1.81. But the RayHom is the best bargain!

I use these in almost every device in our home. From kids toys, to remote controls, to my DSLR flash units... pretty much anything. The only flaw I've found is they are strangely a little shorter than standard AA batteries, so the one thing they do not work in is my Apple Magic Wireless Mouse. The positive contacts don't touch properly and they are not recognized. Other than that, they are superior to any rechargeable batteries I've owned (besides the Eneloop ones, which are much more expensive but seem to perform about the same).

Most work as expected without issues. A couple do not hold a charge well.

These don't always fit the way you would hope in tight spaces.

Great buy, although I haven't used it long enough to comment on the longevity. But so far, it seems to be holding power quite well. I assume it will last as well. One thing is, remember to charge it first before first usage! If you don't, you may come here writing that it doesn't hold much power! It comes with a about 45% charge only!

The 2800 Mah rating is not a true rating. The batteries after a few full discharge and charge in a professional charger only show around 2100 Mah . That’s is about 75% of the rating stated

They won't fit in my sons electric tooth brush. They are slightly bigger around than a typical AA battery. Haven't tried them in anything else yet.

There’s lasts way longer in my GPS than energizer or Duracell alkaline batteries
