Good battery - GREAT warranty
356899
Performed great for 6 months and then lost the ability to charge.  My laptop is used all day/every day and I got great performance between charges on this battery (and the replacement).  I'm giving it 5 stars because Runpower also backs up their products with a fantastic no hassle warranty.  Jack at Runpower was quick to respond to my email and had the replacement battery shipped immediately.  The new battery was in my laptop in a matter of days!  If you are looking for a replacement battery for your laptop, look no further.  Just knowing you have a company that stands behind their battery warranty (if needed) is enough for me.

Great battery so far. Last just as a little longer than the factory original.  I order the extended 7000mAh battery about a year ago and it worked fantastic! !  Would last almost 3 days with continued use!  But over time.. it just began to feel too heavy.. so decided to switch back to the small batter. No hesitation to order this replacement from Zero Lemon since the extended worked so great.  Will definitely buy my next battery from this company!!

This battery is excellent. My OEM had died and this battery last considerably longer. I've used the battery for several months now and so far I am pleased with it's performance!

Fast shipping, product as described. I like the one year warranty, plus customer service phone # & website on the outside of the box the battery came in, readily avail info if needed. HPG60 computer is working fine with this battery, but I just installed it today, so I cannot vouch for its longevity.

Quite a good battery. No complaints works well and seems to be holding charge like new. I have been using it for a few months and no change with how it performs. Be sure to do a full discharge recharge cycle before going back to regular charging habits.

I have been very pleased with the functioning of this new battery, which replaces a Belkin Battery I had for several years.  There have been two interruptions thus far in my electrical service since I installed this battery in November 2006.  On both occasions there was no interruption in my ability to use my computer or any of the accessories which are also in backup through this battery. It has excellent staying power for my needs should there be future power failures.

Received the new battery fairly quickly and installed it with little effort and the laptop has been running great. We had to replace the original manufacturers battery because it wasn't holding a charge. We have now had this battery installed for over 1 month and use the laptop on a regular basis and have had no issues. The company has been great and followed up to make sure everything was working.

I've had this battery for a while now and have had no problems whatsoever. It seems like a good battery as far as I can tell.

The battery was delivered promptly and was exactly as advertised.  I would not hesitate to buy from them again.  In fact, you can count on it.

It wasn't until I began to write this review that I noted there is nothing in Amazon's description of this battery about a warranty. Nor is there anything to be found about a warranty on the distributor's website. though they do show a US toll-free number for customer support. MaximalPower also exhibits at at least three very expensive trade shows, so I guess there is some substance to the company.

  In any event, I suppose a warranty isn't all that important with a product this inexpensive or so subject to user abuse.

  The battery works - and that is what it is supposed to do. MaximalPower suggests a 10 hour initial charge and 2 hours thereafter. They also suggest that it will take 3 to 5 charge/discharge cycles before the battery is fully conditioned. This is in line with the recommendations of other manufacturers.

  Construction quality seems high.

  I have no sophisticated tools for testing batteries and I am not about to subject my camcorder to hour upon hour of recording just to see how long the battery will last. Two hours was plenty for me and the power meter on the camcorder still showed two bars. Experience tells me that there's enough power left for another hour's shooting. Carry the original battery with this and you should have enough power for five hours or so of shooting, provided you are not using any accessories (such as microphones) that draw upon the camera for power. Not bad at all.

  The battery is larger than the 1360mAh CGA-DU14 that comes with the camcorder. It is just a hair shorter than the fully extended optical viewfinder, so it doesn't interfere with operations at all. The battery fits as snugly on the camcorder as the original.

  What I don't know and won't know for some time is how the battery performs with use. How many recharge cycles will it provide? In my experience, a good lithium-ion battery will last for about 300 cycles. However most of the generic batteries, such as this, that I have used have rarely made it to 100 cycles.

  We shall see. For the moment, this battery provides everything it promises.

I have had this battery for three days now and, so far, it holds the charge very well. I go all day long with moderate usage with checking email all the time, listening to music, and watching YouTube.
My Note 4 is almost three years old and the original battery started giving up. I had to charge it several times a day, which is not a problem. However, the phone would spontaneously reboot when the battery level approached around 30%. Or I would have 30% battery left and then in minutes I would have zero!
I ordered this zero lemon battery and it gave my phone a new life. It is so great to gain back the confidence in my Note 4, which is still a very capable phone. I am so happy I do not have to replace it just yet. As I said, I had this new ZeroLemon battery for few days and let it discharged to 2% and it perform very well on the low percentages (the phone did not reboot  as it is with my original dying battery).
I will update my review after few months of usage. I hope that the battery continue to perform!
The seller has an additional 6 months warranty if you register for it. I did and now I have 12 months warranty.

I bought one of these batteries about 6 years ago and used it as my second battery, swapping it with the primary when it ran low.  I took about 7 trips and made extensive use of it then, and sporadically across the years in between.  Overall, I found it to perform just as well as the OEM battery.

The battery didn't wear down gradually.  It was a matter of just a few uses where I noticed a significant drop in the amount of time that the battery would work.  Still... 6 years is a long time.  I am taking a chance with another set of batteries that comes with a tripod accessory, but have a feeling I might regret not having bought another one of these.  ;-)

With a battery product, it's difficult to rate early on. The product arrived quickly (PRIME 2 DAY), and so far, the batteries are holding good charge. Given this continues without incident, this is a great value.
UPDATE: After 18 months, both batteries began to show degradation. I was switching between the two batteries, so this happened far too fast. The one battery swelled, and the other failed to hold a decent charge. That said, two quick messages to PowerBear, and they honored their 24 month warranty, covering both batteries.

There are a lot of these batteries on the list and many are made by the Tenergy Corp. If you order one, make sure the company you are ordering it from gives you a stated warranty period. I thought I had ordered one with a one year warranty. My battery failed after about 5 months of use. When I wrote about getting a replacement I was told by the Battery Superstore that the warranty was only for 90 days. Expensive battery  for the length of time it functioned.

This battery worked great but is no longer holding a charge at all.  I purchased this battery 11 months and 22 days ago so I'm within the 12 month warranty period, how to I obtain support?
