Good battery for Toughbook CF
352070
Battery arrived on time and was a perfect fit for our older CF52.  Battery life so far has been excellent and comparable to the OEM battery.

So far not bad. As I use a couple different programs to monitor the battery overall condition, it has yet to go over the 100F mark. Which means that it is staying away from the danger zone, of 120F.

I have ran through several batteries that ended up in the 120, some faster than others.

I am following the advice of the manufacturer and fully discharging it down to 0% before refilling back to 100% five to seven times.

The only question I am not sure of , really two is if fast charging the battery ok, and if anybody has tried the battery with qi. As I have a question charging cover (that works) and I am curious.

I may update later, and the score if needed. Update,  this battery  is working well. I even did a unique experiment.  While having the WiFi on along with the near field communication  (nfc), see if I  could use tap and pay without any  sim card. And it passed.  So as it passed that and lasted over 10 hours after a full charge a couple of times, I feel alright to give this product  a star upgrade from 3 to 5 stars.

Ordered this battery to work with my Quanum Nova (Cheerson CX-20) and fit perfect in the battery housing. Thickness of the battery fit perfectly but there is still more room for a wider battery. It charges and balances fine with all cells providing a good amount of current. I am getting 8-9 minute flights with a full action camera payload and still have enough juice for emergencies. I ordered these over going to my local hobby shop mainly because of the price delivery option. Time will tell if they last or suffer any current sag over several cycles. Indicated dimensions (not including wires) are accurate.

The price and capacity of this battery for my Icom radio was just right, sure you can get higher capacity batteries, but at 2x the cost, this one seemed just right.  I've used it on my radio for all day use, the stock battery fell just short of that sometimes going flat before the end of the day, this one, though only used a few times, never fell short, and works with the stock included battery charger with my IC-F21GM

I bought two of these over the last couple of months. They seem to work great. The problem with most aftermarket Macbook Pro batteries on Amazon are that they are a lower Watt hour than the factory battery. However, this battery matches the factory specs.

Be aware that once you replace the battery, it takes a couple of charge cycles for the correct battery life percentage to show up.

I like it so far.  I have a 17" laptop display and this battery lasts a little over an hour.

I am satisfied with this battery. I purchased this together with a Thorfire C8s flashlight. I am fairly new to the Li-on batteries, but have used a similar unprotected style 18650. The charger I use would overcharge the unprotected battery, however this one charges to exactly 4.2V. Just as a test I ran a full charge, High Beam, for 1hr 43 min, before the low charge level strobe kicked in. Completely acceptable for my use. as long as I get an acceptable life out of this battery, I will continue to use this brand. I should have bought the 2 pack. Better deal, and I believe you get a storage case with it.

 In the few weeks since I've purchased this Battery, I decided to get a better charger (Opus bt-c3100v2.2), one that would handle all my different charging needs. This particular model is also an analyser. I have run 2 tests on this and have come up with 2560mAh both times, in different slots. That coincides with a 5 hour discharge at 500mAh. Not really complaining, because I do still think its a good battery. Still a good deal if you buy 2.

Appears to be a good quality battery replacement for MacBook Pro 13. At 5800mAh it should last as long as OEM which is almost 7 hours. Came with 2 precision sized Phillips screwdrivers for easy install. Good buy at good price. Competitors asking twice the price.

Turned out fine.  Very long lasting battery.  Cover fit well.  Kind of worried about dropping it.
Might go for the Zero Lemon 10,000 battery.  Looks like it comes with a very rugged cover.
But, this one is great if you're not as concerned about dropping it as I am.

This battery has the highest capacity and reviews( number and rating for a replacement battery. The screw drivers could be stronger because I tried using the torx screwdrivers on my retina MacBook Pro and the drivers heads stripped and the screws didn't budge.

This battery is a very inexpensive replacement\backup for several camera makes and models, including the Fujifilm NP-50 used in my&nbsp;<a data-hook="product-link-linked" class="a-link-normal" href="/Fujifilm-FinePix-F200EXR-12MP-Super-CCD-Digital-Camera-with-5x-Wide-Angle-Dual-Image-Stabilized-Optical-Zoom/dp/B001R23JMQ/ref=cm_cr_arp_d_rvw_txt?ie=UTF8">Fujifilm FinePix F200EXR 12MP Super CCD Digital Camera with 5x Wide Angle Dual Image Stabilized Optical Zoom</a>.

The battery is marked 1400mAh, which is higher capacity than my OEM NP-50 marked 1000mAh. I'm not really sure that the marking is accurate since it charged in 1.5 hours, compared to just under 2 hours for the NP-50. It would stand to reason that a higher capacity battery should take longer to charge, not less time. Either way, I have taken over 200 pictures with this battery and it hasn't needed a recharge yet.

The low price alone makes this worth having as a backup. I always start off with my NP-50 in the camera and keep my off brand backups in the case.

Recommended!

I purchased this battery from eForCity, which is one of the non-Prime sellers I've used a few times. Usually I prefer to buy batteries like this from Prime sellers, as one can get a full refund if the item is defective. Trouble is for batteries that fit the SLB-10A form factor, Prime sellers want at least double.

The first pleasant surprise was the speed of delivery. The battery came in a small poly envelope within three days of ordering.

The second pleasant surprise was I got a better battery than what I ordered. The advertised capacity is 1050 mAh. The delivered capacity is 1400 mAh. So this battery should last longer than the original.

What about actual practice? I use this battery with a Samsung WB150F camera. Both the original battery and this one last for about a day, or around 85 pictures. So the real-world capacity is about the same, even though this battery costs 1/5 of the original Samsung brand battery.

Four stars for a battery that works as advertised at a great price. If the battery works as well in six months time, I'd make it five!

Battery worked well in Yaesu FT-60R.  Battery was charged and I was able to use a radio I had not used in several years.
