Biswaye XBAT200 Lithium Battery Replacement for Shark ION Rocket IONFlex ION F80 IONFlex 2X Cordless Vacuums, 25.2V Battery

I have found that this battery works the same as the battery that came with the vacuum. It powers the unit just as long as the original battery. I can't attest to its longevity at this time due to the short time I have had it, but at this point it is fine. The only difference I see is when the battery is run down to the last indicator light it did not flash like the original battery letting you know it was about to run out of power. It just went out and the vacuum stopped. But that being said it is no big deal because the original battery only flashed for a short time before it went dead. This battery is a very good deal too considering the price of buying the original named battery.

The battery arrived in 2 days. Charged it up and used it for the 1st time today. It lasted for 20 minutes with the Shark Ion Flex on high so about the same as the original battery. As the battery is less expensive then a 2nd battery from Shark it was a good value, worked as well as the original, slid in and out without an issue. In fact if I didn't know it was not the original I would never have known the difference. If deciding if a good value (it is) and it works. As for longevity I have no idea as said just got it, as well as the Ion Flex so time will tell which one will last longer (my guess is they will be about the same).

I have bought before from them, a D7 replacement that has worked great. This, for a Shark stick, is defective. First, when my wife tried to use the vac, it would not start. Huuum. Not good. What could she have done wrong? I tried and it worked for me, but only lasted 12 minutes on std mode. The factory battery, which is still fine, goes almost 20. The second time, after 4 minutes (I was timing by now) the vac turned off. Huuum.Not good. Turned it right back on it ran for a few minutes; off again. Three strikes, you're out!

First one I received died very fast and vacuum would not power on half the time using battery. Once I got my replacement battery in it looked different and worked perfectly! I think it even has more power than my manufactured one and lasts longer than 20 mins. I gave it 5 stars because the second one works perfectly, And for the value!

My Shark battery would die half way through vacuuming my house. I bought this as a substitute for a Shark ION at half the cost and works just as good as my other battery. I've had it just a few days and doesn't seem like it's going to give any problems. Has same strength and suction and works just as long! I'd say for the money, I'm getting my money's worth!

Battery looks and fits like original,,,,

There's not much you can say about a battery. This is as good as the original Shark battery and costs a lot less. When you put the two batteries together they look identical, and seem to work identically.

Great Price. So far so good. Let's see how long it will last
