We are committed to satisfying every customer through our reliable battery life, improved rechargeability, stability, and guaranteed compatibility. We have gained increasing popularity for our commitment and attention to detail to customer needs. Moreover, Synergy Digital carries an array of hard-to-find batteries so customers can easily and quickly find the right battery they need.
Travel Use
Meeting the challenges of worldwide voltage and European electrical sockets, you can easily charge up your AA and AAA rechargeable batteries using Synergy Digital’s Battery Charger at home and on the go. The compact, 1.5” W x 4.25” H x 2.75” L battery charger is outfitted with a standard, flip-out AC plug for easy charging, featuring universal 110-220 VAC voltage adjustment for worldwide travel use. Additionally, it also comes with a European adapter featuring two round pins to accommodate most continental European outlets.
High-Energy Density
Each Synergy Digital AA Battery provides 1.25 volts of power with 2800 mAh of capacity to provide long-lasting, continual use. Boasting a high-energy density and high-power capability at a more constant rate, the battery is made of Nickel Metal Hydride to provide long-lasting, reliable power. An Ni-MH battery delivers substantially more current than an alkaline battery and the high hydrogen content of Nickel Metal Hydride is double the battery capacity compared to nickel-cadmium batteries. Furthermore, each battery is made with high-quality Japanese cells to ensure long-lasting use so you never have to worry about draining off the battery the moment you really need it.
Suitable for NiMH and NiCd Batteries
Designed to replenish the energy capacity in your batteries quickly and efficiently, the Synergy Digital Battery Charger is suitable for NiMH and NiCd rechargeable AA and AAA batteries. Simply place your rechargeable batteries in the charger, flip open the AC plug and place the charger in your wall outlet. The voltage of the battery will increase during the charging process until the battery is fully charged, and the green light indicator will turn on when charging is complete.
Long-Term Value with Safer Usage
Unlike single-use batteries that have to be thrown out after a short period of time, Synergy Digital’s Ni-MH, 2800 mAh Ultra Hi-Capacity Rechargeable AA Batteries can be recharged up to 1,000 times so there’s less waste. Not only do you get more bang for your buck, but Nickel Metal Hydride is also free of toxic heavy metals to deliver ultra-strong power for your devices over and over again.
Four Pack of Batteries
The Synergy Digital Battery Charger comes complete with four, Ni-MH, 2800 mAh Ultra Hi-Capacity Rechargeable AA Batteries, allowing you to power up any device that accepts rechargeable AA batteries. With this 4-pack of Nickel Metal Hydride rechargeable batteries, you can power your household electronics, including digital cameras, photo equipment, flashlights, gaming devices, toys, clocks and more. For best performance, recharge whenever energy capacity drops 30- 50% below its peak capacity.

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.

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.

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.

I bought this mainly for my camera and all it needs is 4 AA batteries so this was perfect for just that. I stopped using my camera for quite a while before i got this battery charger because I was sick of buying disposable batteries even though I was getting energizer, it seemed to always eat up the batteries too soon! Sometimes I would be out and bring my camera and have no idea that as I am taking pictures "Battery Exhausted" would pop up and my camera would shut down. I have had this charger for 2 weeks now and haven't even had to charge them once since the initial charge. I am very pleased with how fast they charge and how long they last! And knowing that you can charge them up to 1000 times?! That's awesome! Then all you need to do is buy battery replacements. The price for this set was well worth the money.

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

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.

It's hard to find a better value in the rechargeable battery world. The charger is excellent. Relatively quick charging, with indicator lights that tell you when it's charging and, when it's done.(you really want this feature in a charger) When not in use the electrical plug folds flat into the charger. Makes storage more convienent. The included batteries are fine. Heck, they might be excellent, I ain't gonna spend an infinite amount of time compairing batteries. I can tell you the higher the mAH rating the more "juice" they got. 2800 is pretty darn high. I purchased additional batteries(can't remember brand) with a lower mAH rating that I charge with this charger also. Have converted entire household over to rechargeable. Couldn't be happier. In response to people who mention they don't last long in digital cameras. Digital cameras suck the "juice" out of a battery faster than a teenager can suck the funds out of your bank account. It's not the battery, it's the camera.

I am disappointed in the charge length of these batteries. I bought them for my Nikon Coolpix L810 camera. They didn't last long at all at the wedding I attended. Thank goodness I slipped some alkaline batteries into my camera bag or I would have been done with taking photos before the reception was over.
