Know the name of the product that is highly rated, such as the NinjaBatt.

I was told by my neighbor that the NinjaBatt was the best battery to by for my computer. All I can say is that he was Right, the battery charged up to 100% in no time and has outlasted my old battery (even when it was new) by far.I would recommend this battery for anyone that needs a replacement battery for their computer.

Pros
  • Easy to install. Good performance. Lasts 4 hours.
Cons
  • The battery may not provide the same level of power output as the original Toshiba battery

Good Product for my opinion

Fit correctly the first try unlike some other replacement products that never quite fit. So far its been a good investment

Pros
  • PREMIUM QUALITY REPLACEMENT NOTEBOOK BATTERY: Bring your laptop back to life with Ninjabatt's high quality laptop battery - Made of high quality materials, top grade battery cells and packed with safety features.
Cons
  • The battery may not have the same level of power output as the original Toshiba battery

Excellent new battery for an older laptop.

I've had my HP EliteBook 8440p for several years now, and while it may be 'outdated' it still does what I need it to without issue, with the exception of the original battery being about useless - dying within 5 minutes.My luck with aftermarket batteries has generally been pretty negative, but this one seems to be the exception. Under normal fairly light usage (Web browsing, quickbooks, email, etc) I get a little over 2 hours of battery life. About the same I got with the OEM battery when it…

Pros
  • TRUE CHARGING CAPACITY THAT LASTS: Every one of our replacement notebook batteries are tested to meet OEM specifications. Our 6 cells Li-ion battery is rated at 48wH/4400mAh/10.8V - true charge capacity that won’t let you or your laptop down.
Cons
  • The battery may not be compatible with some third-party chargers

Never tested it again, I thought , allis good. Power out this am, laptop crashed, (no big, it recovered), battery showed full chgagain, just like the first one, but was completely dead.I have no idea when the battery started failing , it could have been a complete fail a…

Don’t Waste Your Money

I took a chance buying this battery for my Toshiba laptop instead of paying for a more expensive Toshiba battery. Boy, am I sorry that I did. The first couple of charges lasted only about one to one and one-half hours. Full charges currently last less than a half hour and my laptop has a solid state hard drive which consumes very little power. If the laptop is off overnight, the battery is completely discharged by next morning.The battery icon on my taskbar was completely useless as my laptop…

Pros
  • Has built-in overcharge and over-discharge protection
Cons
  • The battery may not be able to handle heavy usage for extended periods of time

good fit and finish

plugged right in no problems, charged it before i used it , seems to not last as long as original , but for the money this will work just fine

Pros
  • Battery life unknown since we recently purchased it. Seems very good up to this point.
Cons
  • I used it for less than a week and would no longer hold a charge

Holds a charge for my purposes very well

Got it in just a few days. My battery in my 7 or 8 year old Toshiba was totally dead. Installed new one in a few seconds. It already had some charge so I let it get up to 100% unplugged it and used the computer very lightly but checking it this morning it is still a 65% hopefully it will run several hours with heavier use, time will tell bit for now I couldn't be happier.

Pros
  • VERY NICE, FITS PERFECT, VERY CONVENIENT, AND EILIMATES A LONG BULKY CORD. WORKS GREAT
Cons
  • The battery may cause overheating issues in some laptops

Toshiba Replacement Battery

We are really pleased with the replacement battery for our laptop, and especially how quickly it was shipped. We also appreciated the instructions on not only the specs on the battery, but also how to recharge it and take special care of it (the Do's & Don'ts). Our laptop was a hand-me-down from our son :>) so we didn't have any of the information about the laptop itself. Thanks so much.

Pros
  • Toshiba laptop. Works great
Cons
  • The battery may not provide the same level of voltage output as the original Toshiba battery

Happy with purchase

I am happy with this battery. Battery life is about 2 hours, I am fine with that, I don’t need a battery that needs to last hours and hours. I will buy from this company again.

Pros
  • Enables you to work on the go without worrying about battery life
Cons
  • The battery may not hold a charge for as long as the original Toshiba battery

Revainrating 5 out of 5

I got better than I expected.

The battery arrived a day earlier than expected. It was a perfect fit and it holds a full charge for about 4-1/2 hours. I'm not sure how long the original one was supposed to, but my old one was down to lasting about 45 minutes so this is a great improvement an well worth the money. Professionally packaged. I would buy again.

Pros
  • Received the battery well packaged, on time and was as described!
Cons
  • The battery may not fit properly in all Toshiba A665 and L755 series laptops

So easy to install - charged very quickly

My old laptop battery was completely dead and I was ready to take the laptop into Staples tech support to replace it. But I figured I'd try this first. So glad I did - snapped right in and fully charged within the hour. We'll see if it lasts over time, but if not I'll just buy another - you can't go wrong for the price. Probably would have cost me $150 to do this at Staples.

Pros
  • Battery seems to drain too fast
Cons
  • Some users may experience shorter battery life than expected

Battery for Toshiba laptop.

Purchase this battery for my Toshiba laptop could not be happier both with its performance and the speedy delivery from Revain.

Pros
  • Provides the perfect replacement for your old or damaged battery
Cons
  • The battery may not come with a warranty or satisfaction guarantee

Revainrating 4 out of 5

the battery was not an exact duplicate of the original Toshiba battery.

The green light batter indicator (when the battery was charged)was instead unlit when charged, and red when it was not. But otherwiseit seems to do the job.

Pros
  • Battery is great had an older battery die and this worked like a charm. Worth every penny
Cons
  • The battery may add unnecessary weight to the laptop

NinjaBatt Toshiba A665

The battery doesn't even hold a charge for 30 minutes.This is crazy. Waste of money. I followed all the instructions they gave. I made sure my display is on low resolution. Ensured no app running or any other energy hungry process.The battery is just weak.

Pros
  • Comes with a one-year warranty from the manufacturer
Cons
  • The battery may not provide the same level of performance in extreme temperatures

The battery slipped right in,fit perfectly, and was already charged. I have used it for several days and it works just as described. It's a great value and I would recommend it.

Pros
  • Arrived on time and I liked it. It worked on my laptop
Cons
  • The battery may be more expensive than other replacement options

fits my Toshiba Satellite L670

Was super happy to see this battery at this price point for my aging Toshiba L670. It's been a great laptop and I wasn't ready to upgrade - so when the battery started to go (again) I was happy to see this aftermarket one - with good reviews - available. I charged it fully before turning on the laptop and it charged just like the original would - no issues. Booted right up and works fine. I do tend to keep it plugged in because it is located near a plug - but when I want portability I can…

Pros
  • Fácil rápido
Cons
  • when the battery is discharging and is connected to the power it turns off

Good battery for your laptop

This battery works fine. It only lasts about 3-4 hours before it needs a charge. But that's okay as we need a break from work at that point. I charges quickly. We have even charged it while using the laptop and everything has been fine. I would purchase this item again.

Pros
  • So far so good
Cons
  • Some users may experience compatibility issues with their laptop's power management system

Perfect fit, charged and ready to go.

Battery arrived charged. It was easy to install and fit like a glove just as the original manufacturer's battery. Thanks for attention!

Pros
  • Prevents damage to your laptop from power fluctuations
Cons
  • The battery may not be as energy-efficient as other replacement options
