Laptop Batteries For Sale With Samsung Cells

I am impressed with the form factor of these new high capacity cells. These batteries are incredibly light for the power they provide. I got four of them for travel work. I trust these batteries and this company. You get what you pay for!

I have multiples (5) of these which I have purchased over the past 4 or so years. They charge 123/16340 and 18650 Li (I have not used them for LiFePo cells such as the SureFire 123 batteries however) and IMR 123 batteries nicely. I have used these chargers with Fenix (16340), Olight (IMR 16340) and Surfire (18650) batteries and they have worked well. The display is very helpful for getting a sense of where the batteries are in the charging cycle. This charger does not, to my knowledge recondition batteries. Also, there may be calibration differences among charger or even in one charger itself -- individual charger may read cells' voltages differently including reading them differently in the charger's own left and right channels. This has not been any sort of a problem, as far as I can tell, with the cells I have been charging. Another small niggle is that the input cable fits a bit loosely into the charger.

Coast’s lithium battery ZX450 all batteries that Coast supply are excellent. Reason I say this is because rechargeable lithium batteries sometimes have issues like premature failure. Things like not taking a charge, memory issues, and short run times to name a few. I do handle lion cells as recommended which is important for long life. Coast batteries and my lithium cellular batteries are the only batteries that work as promised regarding rechargeable lithium cells. I expect an a dramatic improvement with rechargeable lithium batteries of all sizes any time.

Excellent product, the best way to test batteries or cells is under load. This is what his device does very well. Very often when I go to find a battery for a device and it does not function, I cannot tell if the device is bad or the battery. This device corrects that problem. Very Happy with this device. Powered off of 4 AA cells, recommend you use Lithium Cells,

I purchased this charger to charge some high capacity batteries that I use for my flash and vertical grip after I found the one I was using would not charge them fully. The best feature is how it charges each battery independently and shows you the status of each cell as well. I also found that I had a couple of batteries that where no good with this charger. Part of the problem with the previous chargers where these bad cells and the lack of ability to identify them. The old charger would simpley indicate everything was charged whereas this unit kept charging the good batteries while identifying the bad one. This is not a super fast charger however I do not see that as an issue sine it does such a great job of FULLY charging your batteries unlike other chargers. You can also use this charger to discharge cells as you see fit. I highly recommend this charger!

Im an Electronics Tech and all that really matters with rechargeable batteries is how much current they can provide per hour. 8 cells at 2500 mA per Hour for this price is better than an excellent deal. They work great and last.

This was a bit of a splurge, but it really does work better for my needs than the single cell unit that came with the camera. 2 batteries can be charged concurrently and monitored as to conditions. Handy! Also plates for Pentax cells, or other brands, allows for charging a variety of cells. Very happy with this gadget!

Great batteries, I'm in the process swaping out all of the alkaline AA in my household items to the Eneloop Ni-MH. It will be great to finally get rid of the dead battery bin sitting in my garage. The higher capacity (milliamp-hour rating) cells are great for flash units. For those of you not familar with Ni-MH (Nickle-Metal Hydride) batteries they do take a while to charge, especially on the small wall plug-in unit if you are charging the higher capacity cells, this is completely normal. If you have a fancy charger with adjustable output I would not reccomend going over 1 times the capacity of the cell. Example: a 1000mAh cell will charge in 1 hour at 1 Amp.

These seem to last as well as Olympus' batteries. All companies use battery manufacturers' loose cells, and add their circuitry and packaging. The Watson folks seem to have done this very well, and their batteries are about a third of the cost of Olympus batteries. You pays your money, and you makes your choice. They have served me well.

These little battery caddies are SWEET. Extremely low risk of short circuits. Batteries are held securely, yet are easy to remove. They can be easily tested while in the caddy. Used cells can simply be inverted to show their status. And inexpensive too! I have since purchased a couple more for AAA cells
