I finally can use my laptop without AC power. It's a good product so far but it's not straight as my original battery so the laptop doesn't sit flat.

This seemed to be the best value for me. The battery is easy to install and has worked well up to now but has only been in for just over a week. It arrived promptly.

So far so good, but like all these types of things, that are not originals, time will tell & it is very early days as I have only been using it for about a week. At the moment when I have charged the battery, as advised, it is telling me I have about 2 + hours, but I have't fully discharged it yet & I hope when I do so & then recharge it I will be told I have about 4 hours usage on the battery, we shall see.

Appears to be up to 4 hours after several re-charges. But then a fault developed and kept shutting down my laptop - but of course this was outside the return date... Green Cell offered a full refund and too be fair, they did. Good customer service, thanks.

My aging Toshiba laptop battery was expiring, so not worth spending a fortune on a genuine Toshiba battery. Having read the reviews on Google the Green Cell make came out very well. The delivery was fast and the battery had about 75% charge when it arrived.
I've run it down a couple of times to give it full charge. The battery is giving me about 5 hours of intermittent usage during the day; the laptop is constantly on and set on high power display.
I am happy with my purchase and the service. I have given the battery a 4 Star rating only because I don't know how long it will last [based on experience with non-genuine camera batteries].
I recommend the battery and the seller to other people.

Ordered on Easter Monday, delivered next day free of charge. Very Impressed with the speed of delivery, especially as I ordered it on a bank holiday. Item was well packed, padded with sponge in a cardboard box by GreenCell, and overwrapped in cardboard by Amazon. The battery fits my Toshiba Satellite laptop perfectly, and arrived with a 70% charge with instructions to let it run down a certain amount and then charge it to get best efficiency . There is also a 12 month warranty card (I think, it's in Polish!!) I have now done 2 cycles where I used it until there was about 10% charge left and then plugged in to recharge the battery and am getting 4-41/2 hours of charge according to my laptop. Very pleased and would definitely recommend GreenCell.

Purchased as a replacement battery for a Toshiba Satellite C50. Out of the box it comes with an estimated 70% charge. after 2-3 charge cycles the battery provided around 4 to 4.5 hours of charge (estimated by Windows battery meter) with our particular model of laptop. Well packaged with warranty information, safety precautions and instructions.
