"Sony 2500 Mah AA Rechargeable Nimh Batteries ""2"" 4-packs (8 Batterys)" Review

my boyfriend and I are hardcore gamers so we used to run through regular duracel batteries quick and waste a lot of money. These batteries, if properly charged last for quite a long time...we use them for our xbox wireless controllers and rock band instruments. Anyway, a two pack is worth it...but don't forget to get the recharger! We bought a pack of four and will gladly get another eight or so...

Energizer Value NiMH Battery Charger with 4 AA Batteries Review

Energizer Value NiMH Battery Charger with 4 AA Batteries
Average Reviews:

This is a good value: you get 2 rechargeable batteries AND a charger for about an Alexander Hamilton. Course, the batteries are 2000 mAh rather than 2500 or 2700, but picky, picky. You put in your batteries, next morning they are good to go. That's the good news.
The bad news: it is an old-fashioned, "dumb" charger of yesteryear. The charge times listed in the instructions are:
AA 1300-2000mAh = 8-12 hours
AA 2100-2500mAh = 13-16 hours
AAA 850-900mAh = 11-12 hours
Output:
AA 2.4v x 2 = 190mA
AAA 2.4v x 2 = 90mA
There are no colored or blinky LED's to tell you when your batteries are done. You just have to keep track of when the listed time is up. Also, you must charge 2 or 4 batteries; a problem, since I have some lights that use 1 or 3 batteries (D'Oh; you have come up with a creative solution so you have 2 or 4 to re-charge).
Judging by the times, however, I assume that this an old-time trickle charger. If so, it is OK if you forget to take your batteries the next morning; they will keep OK for a few days still in the charger. Also, NiCd's should be OK (I have not tried this yet; don't ask).
With the above reservations, I do recommend this charger. I should also say that it does both AA and AAA. There are molded plugs for both sizes in the case itself; no funky clips to move or break. I have used this for several different AA and AAA rechargeables of different mAh and manufacturers; I just leave them in overnight, and next day they are good to go. I have had no problems.

Targus TG-LCUV Universal Li-Ion Charger Review

Targus TG-LCUV Universal Li-Ion Charger
Average Reviews:

(More customer reviews)
Bought one of these in a jam when we were in Door County; we accidentally left our charger and spare battery for a Sony A-350 camera at home. There aren't many camera stores in the area, but we found this charger randomly at a department store. IT WORKED LIKE A CHARM. The actual charge time for an info-Lithium is more like 1.5 hours, but the difference is by no means a problem. The best thing is that we were going to buy a car charger anyway, which by itself would be more expensive than this. It was also helpful to have a recharge system for our flash batteries.
Long story short, the charger works with AA and AAA batteries (provided they are lithium type) and works with every other major camera company's product I could think of. Buy it, and provided the the manufacturers don't change their formats, it will be one of the last charging tools you'll ever need.

The four AA rechargeables alone are worth the price. The charger is primitive--no automatic shutoff, no on/off switch, no labeling telling you which slots to use if you are charging only two batteries--but it works.
It took me a few minutes to realize that there was a plastic film that needed to be removed from the contacts on the charger before it would work.

Hitech iC-808UL-LCD 8 Bank Smart Quick Charger/ Discharger with LCD Display for AA, AAA Batteries Review

Hitech iC-808UL-LCD 8 Bank Smart Quick Charger/ Discharger with LCD Display for AA, AAA Batteries

I've only had this a week, but since there are no reviews I'll throw one up, so to speak.
I have other chargers - a BC9009 and a Maha C800s - if I've remembered the models correctly - and I like 'em both. So why did I buy this one?
Well, for one thing, it's half the price of a Maha charger, and the charging current doesn't look to be as high. Why is that good? Because I like to be easy on the batteries. The Maha charger has one flaw as far as I'm concerned, the "soft" charge should be the default, not the "fast" charge that heats the batteries up. Since the tiny LCD wording saying "soft charge" is so hard to read, I sometimes miss getting it on, and shorten the lives of the batteries unnecessarily, which annoys me when it happens. So I've taken to keeping a charged battery in the maha at all times to hold it in "soft" mode... which turns it into a 7-cell charger.
Now the Maha does pulse charging, which is supposedly better, while from what I can tell this one doesn't. However, I seem to be getting a lot of utility from it. It does allow you to slap in a bunch of different batteries, and only charges them as long as they need. In the real world, this often means a fairly fast charge even without heating them up.
The unit being reviewed seems physically as sturdy as the Maha charger. It has spring clips rather than the more premium clips in the maha, but actually some of my batteries, like panasonics, are too short to complete the circuit in the maha, while they work fine in this one. This one also seems to be more accepting of nearly-dead batteries than the maha - I often have to jump through hoops to put a slight charge on a cell to get the maha to even recognize it.
Another thing I like about this one is that it comes with both a 110v power supply and a 12v car adapter. One reason I like this is that I have a 12v solar power system, and that means this charger can be seamlessly switched to that system, just at a time when my need to recharge batteries (power outages, etc) may be highest.
I imagine that this "Hi Tech" isn't as high tech as the Maha, but it may be high tech enough to be a good deal at half the price. I find the display to be easy on the eyes, the ergonomics to be decent, and the cycle time to be about like the Maha on "soft" mode... only I don't have to push a button to get it to that mode.
Frankly, Either of the 8-bank chargers is more use to me than the BC-9009, which also doesn't do pulse charging and was pricy. It is capable of some tricks the others aren't, but who has the time to program it? I find I keep it in a drawer and only use it when I have the time to run batteries through a time-consuming testing process.
So I'm giving this 4 stars at the current price of $30. And if I haven't come back to change it, then my opinion hasn't changed - I always go back and edit a review if my opinion of the product changes.
So far, so good.

Sanyo 2,700 mAh AA NiMH Rechargeable Batteries (4-Pack) Review

Sanyo 2,700 mAh AA NiMH Rechargeable Batteries (4-Pack)
Average Reviews:

(More customer reviews)
These are quality batteries w/ 2x's more power and [Longer RUNNING time] than most lower capacity NIMH batteries, including the "ready to use"/ Low self-discharge (LSD) types!
Never thought I would care about writing battery reviews, but the High capacity rechargeables are getting a bad rap from some reviewers b/c they have to be charged (before) use, in order to get back their capacity, after being left (un-used) for more than ~ 3-4wks. Their stored power when [NOT in USE / device turned OFF] is lost faster than batts that keep hold of theirs longer = the LSD types like Imedion 2100 mAh -or- Eneloop 2000 mAh.
-BUT these high capacity batts (2700- 2900 mAh) have an intended purpose, which is a reason the top companies make Both types in the 1st place.
[In Storage]
Yes, the LSDs are useful b/c they have a [Longer STORAGE time] (before needing to be recharged) than the high capacity types. Thus the LSDs are "ready to use" and good for seldom used devices & intermittent usage. However, this doesn't negate the effectiveness of 2700-2900 mAH made by quality brands.
[In Operation]
Not all users (all the time) need a rechargeable for good shelf-life... Some need it for High power & LONG run time for "shorter" segments = 1- 20 days (i.e., photo shoot, day-hike/bike/caving, day at the beach with ur RC (radio-controlled) toys, holiday lighting, etc, etc. And a quality brand (2700-2900 mAh) will do the job.
The decision is [WHEN] do you pick a :(High Capacity/ high self-discharge) -or- (Low Capacity/ Low Self- discharge)...Not picking the universal "better" one. The "best" would be a High capacity & LSD & Rechargeable all in one!- but that's not available yet.
Now, Sanyo's REAL competition is ( Powerex AA 2700mAh NiMH ). They're both good -I would pick 1 over the other, based on sale price or latest technology release.

Duracell Value Charger With 4AA Pre Charged Rechargeable Nimh Batteries, CEF14DX4N Review

Duracell Value Charger With 4AA Pre Charged Rechargeable Nimh Batteries, CEF14DX4N
Average Reviews:

(More customer reviews)
This package (CEF14DX4N) includes four new Duracell 'Pre Charged' NiMH AA cells, plus a simple charger. The batteries are similar to the Sanyo eneloop low-self-discharge cells. In fact, based on their identical technical specifications and physical shapes of (+) and (-) terminals, I am convinced that the Duracell Pre Charged AA is actually SANYO eneloop AA underneath a different wrapper. Therefore all the good things you heard about eneloop apply to Duracell 'Pre Charged', too.
The 'value charger' (CEF14) included here, however, is not a good value because:
1. It is a timer-based dumb charger, meaning that it doesn't detect when cells are full charged. It simply charges at 360mA for 6 hours and turns off. You have to wait until your cells are fully exhausted before recharging, otherwise they will be over-charged. With a 'smart' charger, you may choose to top-off your rechargeable cells any time.
2. It can only charge either 2 or 4 AA cells in pairs. This is very inconvenient if you have appliances that require odd number of cells.
3. It can only charge two AAA cells, and you cannot charge any more AA cells at the same time.
My advice is to get the CEF23DX4N package for just a few dollars more (*). It comes with four Duracell Pre Charged cells (2xAA + 2xAAA), but the included charger (CEF23) is far superior in every aspect. It even operates from your vehicle battery, and doubles as an USB charger, too.
[Update on Dec 24, 2008]
I was only half-right when I boldly proclaimed that "Duracell Pre Charged AA are rebranded Sanyo eneloop cells" in my original review. It turns out that the first batch of Duracell AA cells I bought from Amazon are made in Japan, and those are identical to eneloop (both mechanically and electrically). But lately I bought some more Duracell AA from a warehouse club. Those are made in China, and they are identical to the Rayovac Hybrid.
[Update on Feb 15, 2010]
I have confirmed that the new Duracell 'Value Charger' has several improvements over the old model:
- Works from 100-240V AC (instead of just 120V AC)
- Able to charge 4 AAA at a time (instead of just two)
- Semi-smart charge termination (stops when BOTH cells are fully charged)
The only remaining drawback is thet it charges in pairs only.
(*) [Update on Oct 7, 2010]:
Duracell has discontinued the excellent CEF23 charger (at least in the US) last year. So prices for the remaining inventory have skyrocketed. If you need an inexpensive charger that can handle individual cell, consider the Sanyo eneloop MDR02 2-cell charger.
