Since better quality batteries aren't available at any price
590031
Seems to be holding up and holds a charge. For some reason it will not charge to 100%, it only goes to 99%. Since better quality batteries aren't available at any price, I'd say this one isn't a bad choice.

Bought two of these and they worked fine for 10 months but neither will hold a charge longer than a couple days, now. When put on the charger they go from full empty to full full in about 5 minutes but are only capable of lasting for very few photos or sitting idle for 2 days. My 12 year old Canon battery still works fine but doesn't hold a charge as long as when new. It "only" lasts for a month or so and can still take many, many photos. Inferior grade lithium cells used for these cheap batteries?

I just tried this battery pack one more time. It lasted a little over a year and then broke. It charges no problem but won't charge anything and the flashlight won't work either. For $40 I feel like the quality is poor and won't recommend. I know other people with batteries that have lasted for years and are still working.

The whole reason I bought this was for the batteries. I had dropped my other spare non OEM battery in water (Which work as well as the OEM battery) and needed some more spares. These batteries are awful. If one was defective, it would be somewhat understandable, but BOTH batteries put together have less life than a single one of my previous batteries. This just shows how poor quality these batteries are. To confirm, that it was the batteries and not the new charger, I had charged these vivitar batteries with my OEM charger and they still did not last for long. I'm extremely disappointed in this purchase.

The only reason this bundle deserves two stars is because the grip, wall charger, and remote all work as described. I have yet to try the car charger, although I feel that I will have very little use for it, since I prepare all of my photography needs at home and not in my car.

I have one of these units plugged into my motorhome's batteries. It & the minimal electricity cost, is a much greater value than having to replace dead batteries (2 of them at $300 each) every few years.

Well I got 2 of these about two and a half months ago and both are now useless and won't charge. i tried all the tricks. So I took one apart (why send them back . You'll see what I'm saying). The batteries in them are not name brand the name on them is "High Star"  a INTERNET search gets only one hit from china. Even worse, china does make some good products, the batteries are only 1500 mAmp hours so if you do the math that's 3 amp hours for a pack of ten  @ 18v Not the 4 amp hr stated. My test on a good cell from the pack was only 1070 mAmp hr. I didn't bother to test the discharge rate.
So.... If you use a lot of battery packs spend the $150 and get a battery tab welder from Amazon. Its simple to put in good batteries at less than half the price of a new one. I use Samnsung 25r 18650 cells 2500 mAmp hr and 20Amp discharge. My small packs (5 cells) last as long as the Ryobi big packs or at leaste 80%. Sony & LG cells are good too. Costs $40 to rebuilds a big pack that's better then new by quite a bit.

Someone at the sellers place pulled the tab in the battery cover that makes them 'work.' They ran out of batteries before we could give them as a gift probably from bouncing around on shipping trucks. And new batteries are not working at all. Too late to replace. Piece of junk. :(

Hate how all brand name batteries are at least $50 no matter the actual capacity. These, as everyone knows, is super low capacity. The blame is of course the design of the a7 cameras being too small to take a larger capacity battery.

Not OEM Genuine battery, looses charge very quickly.

Arrived with dead batteries, too expensive to buy more...

Exactly as advertised.  Easy to replace.  APC does not use the high-rate UPS grade batteries in most of their battery kits.  APC generally does use pretty good quality battery brands.  You can rebuild your existing cases and wiring using decent similar quality batteries and save maybe $100-$150, but if you use the better quality UPS rated high drain rate batteries, you only save about $50-80 per pair of packs.  If you get the replacement batteries much cheaper, then likely they are not very good batteries.

These APC RBC140 packs use 8x 12V 5Ah F2 terminal (0.25 inch) batteries in each frame (16 batteries total as there are 2 Frames to a kit.)  It is easier to replace the entire pack with this unit than to rebuild.  Sourcing good quality batteries is not always easy (most local batteries from a battery store you find are pretty poor and designed for alarm systems, not UPS units).  Shipping is often high for many of them that are not local.  As a quick test check the weight of the SLA replacement batteries compared to the original.  Many local SLA batteries are 15-25% lighter and contain less metal (mostly lead, some have some calcium as well).  Many of the local easy to find battery store batteries only last 1-2 years while the better quality ones and even the APC OEM last 3-6 years.  (I typically get about 5 years.)  CSB, YUASA, BB, CP Vision are good brands.  Werker, Duracell various UB knockoffs are not.

Bought in 2014, and just barely because of how steep I thought the price was back then.

At the time, and up to now, I would have rated it 4 stars, knocking off 1 star due to the high cost. If everything worked great and the price was $200, I would give it a 5 star rating.

Just now, and this is after very seldom use over the 3 years, the supplied rechargeable batteries do not charge through the supplied wall charger when plugged into the flashlight port. Please also note that, at least at the time, the charging port was not waterproof and had a rubber seal, and I think a spare.

Now I am off to try an inexpensive charger dedicated to the 18650 batteries. I found 1 that comes with 4 batteries for $14. The link is provided below for those of you in my same predicament.  So then I can verify that the issue is with the charging port, and the supplied 2600mAh Nitecore batteries are not the issue. Also, I read a review that said these 18650 batteries can be had up to 3500mAh, so anything over that is false advertising.

I am now running it on 8 CR123a batteries. Up to today, I was under the impression that they were the same diameter. They are actually smaller, so I can hear them rattling around loose in the flashlight.

I'd definitely pass on this!

The largest disappointment are the two included rechargeable batteries for the Wiimotes. They are abysmally low rated at 500mAh. Quality NiMH AA batteries these days are at least rated at 2000mAh.

In most cases, I'd say most people would be better off buying rechargeable AA batteries instead of using the batteries that come with this charging station. For folks that get a lot of use from their Wiimotes, you can get rechargeable NiMH AA batteries that will last four to five times longer vs what you get with the battery pack included here.

Rechargeable batteries are great, I use them all the time. It's just unfortunate that to the cost cutting race to the bottom, some customers will get an experience where batteries don't last at all, leaving a sour taste in the mouth regarding rechargeable technology. At the end though, this charging station will get the job done if you're a casual player; just not at a 5-star level. For $11.99 I'm not going to knock on this product too much. As the old saying goes, "you get what you pay for."

Again able to use my drill after quite a while as I was not willing to pay $80. for name brand batteries.

I'd like to start with a tiny explanation. Laptop batteries are actually nothing special. Inside that big batteries, there are 6 AA Rechargeable Li-Ion batteries. Each of those batteries cost give or take $1/piece, some cost much less. There is of course other costs as well, such as the shell (plastic part), connections, storage etc. Whether you buy from this company, or another company, or from the original manufacturer oof the laptop, they all have 6 AA Rechargeable Li-ion batteries. So what makes the premium price? You are basically paying for the name. For instance if you buy the original Toshiba battery instead of OMBAR, you will pay $104 just for the name.
I used to use 12-cell batteries, in order to have an extended time of unplugged usage. Initially, I bought one for ~$150 original Toshiba. Which initially had 4-5 hours life, which deteriorated significantly after a few cycles. And after about 2 years of use, it was not holding more than 15 minutes. I then bought another 12 cell, for around $40 (1/4 the price of original) from another brand. It did not hold up 4-5 hours, perhaps about 3 hours initially. And after 1 year of use, it still holds around 2 hours. In terms of replacement batteries, it is a bit hit or miss. You can get a replacement which can hold up as much as the original, or miserably low (maybe 1/5 of the original's life). If the replacement producer is a known brand in the market, it will not use cheap AA's in order to not tarnish the company name. After all, the cheaper AA's and more expensive AA's will differ less than $5 in total. If you buy an unknown brand's replacement, it will probably use the cheapest products, as their intent would be maximizing their profit in one sale, as the known brands will try to maximize their profit in the long run buy multiple sales. Ombar is one of the more known companies, hence I assume it will not go with the cheapest products, and deteriorate its brand name. For now, as I purchased not a long time ago, I cannot know how it will hold in the long run, but I will update it if something goes wrong, or sub-par.
So why did I go with 6-cell this time, instead of 12-cell. Well, 12 cell is much heavier and bulkier, and since I already have a heavy laptop, I wanted to cut down from the weight a bit. Also, whether it is 6 cell or 12 cell, it will take the same time for the battery to deteriorate. Once it starts losing its capacity to hold the charge, it will take a couple of months to hit rock bottom. So instead of payig double the price for the 12-cell, and replace it every year or year and half, I will instead buy the 6 cell for half the price (and weight) of the 12 cell, and change it every year or year and a half. You can also buy 2 6-cell batteries, and use them sparingly. This way, you will have same or more run time than 1 12 cell, and also your battery will last twice longer since you will not use the same one all the time (Perhaps about 2-3 years). Another advantage is that you can have just one battery (hence not carrying all the weight) when you need the laptop for 2-2:30 hours, and can have both batteries if you need the laptop for about 4-5 hours.
Instead of paying $150 for original 12 cell, or $100 for original 6-cell, I could double that and buy a chromebook, or tablet instead :)
Please note that I received this product with discount in return of my unbiased review, yet I have no obligation to give a good review.

Replacement batteries are cheap, thank goodness. I like the price and the availability, but I have had to buy a couple of these batteries in a 2 year's time.

These are not the higher power batteries but lot's of criticism for most stuff out there and the brand names are insanely priced.  So thought I'd try these hoping slightly older technology would be of better quality over the "new" stuff.  Charger has charged twice and seems too work fine.  Batteries are working in lights camping last week-- so...so far so good on camp trip #1 and time will tell.
