3800mAh RVBAT850 Battery, Battery Replacement for Shark Vacuum, Suitable for Rvbat850 Shark Ion-battery R75, RV761, RV850C, RV1000S, RV1100VL, RV101AE, UR1000SR, RV700_N, RV720_N(2-Prong Connector)

This replaced the battery in my old shark vacuume. So far has held up and decent quality. Works well from what I've noticed so far ill update if needed. Charges fast and it seems to last longer than the original ever did. It was super easy to replace the old 1 and fit right in.

RVBAT850 battery actually works on my Shark robot vacuum (model RV2610WA)! I wasn't sure if it would work since the model number wasn't listed. Battery came in with 60% charge. After replacing the new battery in my Shark robot vacuum, letting it fully charging to 100%, and starting a matrix clean on a room, my Shark robot vacuum is working. The Phillips that they gave me was too small and I'm not sure what the other tool was for.

Worked as a perfect replacement for my Shark Ion vacuum. I've had the vacuum for about 5 years. It had gotten stuck and ran out the battery. It just would not charge again. Replaced with this and was up and running.

Shark wasn’t working, swapped the battery with this one, now we’re working. Lasted two weeks so far so we shall see.

1 month after purchase: I didn't realize how bad my original battery (only 1.5 years old) really was until I replaced it. It was only going for ~10-15 minutes before returning to base to charge and even when running it wasn't picking up everything. This new battery has been great so far. It takes a while to charge (we were used to quick charge cycles on the old, barely functioning battery) but performs very well. Really glad to have our Botvac 80 back to full power and cleaning like a champ. This replacement fits great - just like factory. Hopefully performance will remain high for many months to come. 11 months after purchase: 11 months after purchase, my Botvac gave me a "Please open my dirt bin & push switch DOWN to ON" error. Internet research gave a workaround (pull of charger, open dirt bin, flick on/off switch to off, wait 10 seconds, flip to on, put dirt bin back, put back against charger, activate it and tell it to vacuum - it'll start after it thinks it's fully charged). Internet also said that once you have the error the battery is 'broken' and needs to be replaced. I contacted the seller - they replied promptly and provided this detail on the warranty: -30-Day Money Back Guarantee -6 Month Replacement Warranty -12 Month limited seller's guarantee against manufacturer defects from date of purchase Warranty. - Lifetime Support Guarantee They offered me a % refund or a higher % reduction off a replacement battery. The %'s were both very generous. I opted to replace the battery and it's working great so far. Even though this battery failed within 1 year, I still recommend the battery and the seller.

Item arrived quick and plugged in but will not take a charge. My old battery was getting weak and decided to get this battery as a replacement. The new battery connected and the first run of my Shark RVS1100SRUS was good since the battery arrived with a charge. When it returned to its base to empty and chanrge, it emptied just fine, but will not take a charge of any kind. I have tried resetting it, reinstalling the battery, still doesn't work. Now I have a vacuum that doesn't work due to this battery. I am not sure if I got a bad one or not, but for right now, this isn't a good option if you have a Shark RVS1100SRUS.

This works great in my robo vaccuum.

I havent used it very much yet but so far so good. It dropped right in and my robot went straight to work without even touching the charger first. It worked better than the one that came with my vacuum brand new

Dopo tre anni la mia batteria non durava più, sostituita con questa è devo dire che, dopo aver fatto i primi tre cicli di carica/scarica completa, dura molto più della batteria originale quand'era nuiva, non dico il doppio ma ci si avvicina, quindi per ora molto soddisfatto, vedremo se poi manterrà la capacità nel tempo, altrimenti aggiornerò la recensione, dato che l'originale mi è durata 3 anni mi attendo altrettanto da questa 😉

Je viens de la connecter, tout fonctionne correctement. En ce qui me concerne, je ne l'a pas achetée pour remplacer celle d'un aspirateur. Je recherchais une petite batterie compacte pour alimenter un amplificateur de guitare équipé d'un amplificateur en classe D. Après plusieurs heures, lors des essais avec de fortes sollicitations, la tension est encore à 14,3V, elle ne chute pas ce qui peut laisser penser que l'autonomie de cet ampli de guitare sera intéressante. Je me sert d'un chargeur automatique pour la recharger. Comme il est dit dans les précédents posts, il faut recharger la batterie avant de stocker l'appareil. Le bornier rassemble quatre fils, un noir pour le pôle négatif, un rouge pour le + Batt et deux fils jaunes qui sont utilisés pour mesurer la température des batteries lors de la charge. Compacte, une réserve d'énergie confortable, la sécurité de la technologie Ni-MH, charge rapide, c'est une batterie qui peut servir à beaucoup d'applications nomades comme des enceintes Bluetooth par exemple, en dehors de sa destination première.

Work well !!!!

Obwohl ich den alten Akku mehrmals ausgebaut und extern mit einem anderen Ladegerät geladen und wieder im Neato eingebaut hatte, und ich dem Neato jedesmal gesagt habe, dass er einen neuen Akku hat, lief er einfach nicht. Er meldete mir immer das der Akku geladen werden muss, obwohl die Spannung über 12,5 V war. Verstanden habe ich das nicht!!!! Nach Einbau des neuen Akku wurde dieser offensichtlich erst als "Neu" erkannt und seitdem läuft der Neato wieder.

So pleased with the Morpilot Battery I purchased for my Neato Botvac, "Sadie". I was ecstatic that I could purchase this item through Amazon on Prime for a much better price than available here in Australia and straight away, once inserted and charged, Sadie was off and running like a dream. Love, love Amazon and their myriad products of quality and the service I receive from them is exemplary. Thank-you so much.
