Fancy Buying 14.4V 4000mAh Replacement Battery for Shark RV750, RV720, RV700, Ecovacs Deebot N79 N79S DN622 & Eufy RoboVac 11, 11S, 11S MAX, 12, 15C, 15C MAX, 15T, 30, 30C, 30 MAX, 25C, 35C

Deebot needed a new battery so I figured I give this brand a try as it showed a higher AH rating then the original. Well it has been 28 months and this battery is still going strong! Deebot (N79s) runs for a full 90 minutes before heading back to the charging dock and I have it scheduled to run every day. From a longevity standpoint this replacement battery has better performance then the original battery. Very happy with this purchase and would buy again without hesitation.

Was easy to install and worked perfectly with my eufy robot vacuum. The battery for the vacuum is as good as new now.

Less waste! 1) Saved me money. 2) Don't have trash pick up like a few select towns/cities in my state so reducing waste I have to haul myself is a bonus!!

Worked well on my Shark Ion RV750!

If i could leave no stars, I would. Didn't even last a month and when contacted seller, offered me a 20% refund on a battery that pretty much was dead on arrival. Gave me a lame excuse, that the battery must have been in his warehouse for a month! STAY AWAY

Perfect form, fit, and function. I have no idea if it is providing the amount of amperage advertised but it works great.

It worked good for 7 months but now it only does about 1/2 the job it use to before needing a recharge. When battery goes low vac does not make it back to charger by itself. Contacted Amazon, first CS rep said would print out return mailing label and would be refunded purchase price minus $3.36 restocking fee. When inquired why restocking fee on defective item, said that was required by seller. Eventually referred to supervisor and concern resolved.
