Synergy Digital Camera Battery and Charger, Compatible with Nikon Coolpix L810 Digital Camera Includes: SB257 Charger, 8 x AA Batteries

works well

So I first purchased 1 set of these batteries in November of 2012. Reason for the purchase was that I wasn't to happy with the LENMAR 2700MAH batteries that I purchased at a local Frys electronics store. When I tested the lenmars, the voltage discharge rate could not remain high enough to run my childrens electronics such as their leap pads, and leapster game systems.So I did some research and it came down to either these synergy batteries @ 2800MAH, or the sanyo eneloops @ 2500MAH.I thought why not try the synergy's they have a much higher MAH than the eneloops, and as long as voltage can stay somewhat consistent so that the kids game systems don't shut down early I would be fine with them. These batteries also are 45% savings compared to the sanyo's.I am very impressed with the synergy batteries and since have bought 2 more sets from this vendor.To date none of the batteries have shown defects. They work great in my kids toys, and their toys run about 1.5~ 2 hours longer than they use to when I used the lenmar 2700MAH product.I highly recommend and since have had friends purchase from this vendor as well. I highly recommend this product over duracell, energizer, Rayovac, sony, and lenmar. These are up on the level of sanyo eneloops maybe just a little less effective in the high rate of discharge that the eneloops can produce, but it gets the job done. It is the biggest bang for your buck.If my kids are happy and not complaining, I am happy with no complaints.Thank You

Works well, no issues so far. The batteries I have charged are all done to full and equivalent capacity. I have done about 50 cycles of two sets of AAA so far.

I was a professional photographer/videographer in a previous life. I am now an IT professional. I have been working with computers and technology since the 1980's. I have 3 college degrees - 2 in very technical disciplines. I hope that qualifies this as an expert testimony. This is a good product at a good price. It is not a cheap a piece of junk (technically speaking). I will save you some research time - the NiMH (nickel hydride) batteries are the way to go for this type of a product, these still have a high mAh rating (milliamps) (power output) when many competing products have dropped theirs to lower outputs, the charging unit plugs directly in to a wall outlet - charges as it should - and changes color on indicator lights when done. It works as advertised; you should not be disappointed.

For a battery charger it doesn’t take forever like some chargers do. I had one that took three (3) days to fully charge batteries! This is great!

These are some of the best rechargeble batteries that I've tried. They last a long time I have an digital camera that I use to film youtube videos and to take pictures all around. I've been using these batteries for two days none stop and I haven't charged them at all. They even came charged. Great quality product hands down and the price was great. I definitely recommend this product to anyone that haves a digital camera or something that uses less consume of the batteries life because it will last forever. And it also comes with a adapter for the plug if you live outside of the US you can change it. Excellent product I love it.

Wrong batteries. They charged ok on new charger but did not work on tactical flashlight.

This was a good deal for the price. I bought this because the batteries were rated at 2800mAh. This would be a very good price for the batteries alone if they were actually 2800mAh rated. I have a Powerex smart charger and it reads and displays the actual mAh of the battery. These are only 1700mAh. Not bad, especially considering most of the battery manufacturers overrate their batteries.So for the price if you need some rechargeable batteries and a charger, this a good starting set. These will last about the same time as a generic Alkaline battery.Even though I felt these were a good deal, I took off 2 stars on the rating because of the false labeling of the battery rating. If they had rated these truthfully at 1700mAh or 1800mAh, I would have given them 5 stars.
