Zeikos ZE-QC4000 Rapid AA/AAA Battery Charger AC/DC with Four 3100mAh AA Batteries

I know several of the other reviewers for this product are stating what junk they are. Well I am here to tell you it must be where they are purchasing them from. I received a this product with a Pentax Digital SLR bundle I purchased from Ace Photo Digital well over a year ago and they are still going strong. Wanted to have a second set as a backup (I dislike trying to recycle old single use batteries) so I can charge one set and have another to use the camera with during the charging. I hessitated after reading the bad reviews but then I saw that one of the vendors for them was Ace Photo Digital. Well, needless to say it must be where they are purchased from. I recieved them 2 days ago and they work excellently. No problems charging or using this fine product. Of course the vendor I purchased from was not the lowest priced set (I believe they were second lowest, with free shipping no less). If you are looking to purchase these and are wary of the quality then look for them to be sold by Ace Photo Digital and buy those, You will not be disappointed. (And no, I am not an employee nor am I affiliated with Ace Phot Digital in any way other than a happy previous customer)

This product failed me the first time I tried to use it. I charged the batteries and put them in my camera and when I was ready to take pictures the batteries were dead. They seem to die with a day or two without use. I had them now for a few months I don't think I used them to take more than 50 pictures in about 3 sessions or three charges.

The charger is just OK for a charger that indicates charging when 2 "AAA" or "AA" batteries are inserted on the left or right hand slots.The 4 "AA" Zeikos label "R2U" 3000ma Rated NiMH batteries are abbsolute crap, junk, and not suitable for high load devices such as digital cameras.Ziekos ought to be forced to accurately rate battery capacity and stop over rating battery capacity by 60% or more. [Less than one half the Rated Capacity!]The 4 RU2 NiMH batteries ranged from a low of 1204ma, 1228ma, 1360ma, & 1372ma Averaging 1291ma Following IEC standards in determining battery capacity on a POWEREX MH-C9000 Wizardne Charger-Analyzer. This is terrible for a So Called 3,000ma "AA" rated battery.The Weight is Sub-Standard for this So Called "3000ma NiMH Battery" @ 23Grams each.Top Quality Sanyo or other 2900-3100ma NiMh weigh in at 30Grams each.The varience of capacity is beyond the 10% standard of matched cells.These batteries [Plus other Ziekos Labled NiMH batteries] are of very low quality, weight, have a high failure rate, and actually test less than half the rated capacity.The weakest battery in series determines the longevity, and maximum available current available. These would only last a few minutes in high current devices.Do not waste your money on sub-par, over rated, poor quality NiMH batteries from unknown OEM sources. Buy Name Brand known Quality batteries.Zeikos ought to be taken to task, for false advertising, and dangeriously over rating their NiMH batteries to a point of causing leakage, heating, and explosion or fire hazzard when charged on "Fast" or Rapid Dumb Chargers in an hour or less that are not micro processor controled and monitor each cell temperature and "DeltaV" when fully charged to go to a trickle or maintenance charge or shut off.NakedGary, F.

This charger and (4) '3100' mAh AA's came with Nikon camera as part of a bundle. The charger works as any other is supposed too so no biggie..It's the batteries which need commenting on. My wifes camera displays an icon when it senses the batteries are low and it was coming on way too soon after install of a freshly charged set. Bottom line, I checked the batteries with a Lacrosse Tech Smart Charger which can test for a batteries capacity. Each of the AA's resulted in around 1200 +/-....Seriously?... gee, that is nowhere near 3100 rated. Just so you know...

I purchased 2of these and so far so good. The batteries seem to be just a bit longer than others........have a hard time closing the clip on my camera case...........I've had these batteries and charger for a few months and they will not hold a charge for long. I am constantly recharging. I was using in my TV remote and my computer mouse and when I see the remote and mouse are not working properly, it's the batteries.I broke down and bought regular Duracell..................they last longer in the same devices and I've eleiminated the frustration of constant charging.................

This is perfect, it is small enough to be portable and when plugged into a wall socket gives a fast charge. There are LEDs to let you know the charge status and ensure the battery is inserted properly.

I had purchased a similar item and it was "missplaced" so I needed a new one. I did not want to spend a lot of money but wanted something of quality. This fit the bill. It can be charged by regular houshold outlet or through your car lighter system. Good product

Charge the batteries and they work great.
