Purchased mid November 2024, it’s now March 3 2025. The battery will not hold its charge. I purchased this battery because it was half the price than the shark brand. I guess it’s true, quality is not cheap. Ordering a new battery from shark

I bought two of these for my matching Shark robot vacs (each of which is responsible for 1/2 of the 2,900 sq ft house) and it turns out they are higher capacity than the factory batteries! My vacs are each able to clean their entire designated half of the house now on one charge. I have had these new batteries in for a few months now and they are still doing great. I'm always cautious about buying rechargeable batteries online but these turned out to be legit.

I love my Shark robot vacuum cleaner. It runs regularly on a schedule and manages to collect a shocking amount of dirt in a house that looks and feels clean already. Neglecting to vacuum regularly can lead to a buildup of allergens, dirt and debris can become harder to remove over time, and hard-surface floors like tile and hardwood are less pleasant to walk on. Enough about the virtues of vacuuming…I recently went on travel for two weeks and forgot to disable my 2-year-old robot vacuum. The first day she ran, she managed to get stranded, but no one was there to help her, so her battery became fully depleted and remained that way for the remainder of my travel. Upon my return home, I placed her in the dock to charge- but sadly, she never really took a charge again.I acquired this TQTHL 4500mAh RVBAT850 Battery because it claimed to be a direct-swap replacement for my RVBAT850 battery but with an increased capacity. As soon as it arrived, I installed it in my vacuum and placed it in the dock to charge. The next day, she was off and running like new again. Subjectively, I would say that this battery performs as well as the original when it was new, but it has only been several weeks. I intended to actually bench test the claimed capacity, but once my vacuum was back in operation, I was reluctant to pry it back out (this battery lacked the removal tabs of the original that were pictured in the listing) and put the battery through unnecessary stress. If I have trouble or notice performance issues, I will measure the capacity and update this review, but for now, I am pleased with its performance.

Was easy to replace and my older model robot vacuum has gone from only able to vacuum for 15 minutes back to the hour+ that it worked when we first got it.

I purchased this battery in September 2024 to replace the original shark battery. After just three months of use this battery won't recharge and no longer functions.Do not buy this product.
