Having a dead battery – or a replacement battery packs from the manufacturer that keep dying – can just about ruin your experience with the device. Let us see what’s the best battery for us.
#4 Tenergy Replacement Battery
Compatibility: Roomba 500, 600, 700 and 800 Series
Tenergy is one of the more popular Roomba battery replacement choices, primarily because it is a good value for the money. At about $30 per battery pack, it is not a terribly risky investment. And We can reliably get about 1.5-1.45 hoours out of it, if we push it to the max. While it wasn’t quite as strong as advertised, it certainly did the job for us.

#3 Tattu Replacement Battery
Compatibility: Roomba 500, 600, 700 ,800 and 900 Series
As a reputable company in RC batteries field, you may not hear their products in other field. But, they just released a new Roomba replacement battery, it’s 3500mah Nimh battery, and their user said can last about 2 hours. Much to our surprise is its price, only $13.99, and dispatch directly from USA and offer a 90-day-warranty after your order date. That’s maybe a good choice for us.

#2 Pwr+ Extended Capacity Replacement Battery
Compatibility: Roomba 500, 600, 700 and 800 Series
Despite going for close to $40 per pack, Pwr+ is still a much more affordable option than purchasing from iRobot directly. It also has some nice “extra” features that set it apart from some of the competition.
First and foremost, this is a reputable company with a good track record with Roomba devices. Pwr+ products are certified by a number of trade associations and promise a 50% greater “useful” battery life than the original factory Roomba batteries. Best of all, they have a 30 day money back gaurantee, should anything be clearly wrong. Furthermore, they have excellent phone support and offer free exchanges within the first year of ownership. They also offer to pay for the shipping.

#1 ANewPow Lithium Roomba Replacement Battery
Compatibility: 500, 600, 700, and 800 Series (also Scooba 450)
adding longevity over the default factory batteries. ANewPow is a relative newcomer to the replacement battery market, but they offer a serious upgrade and have received rave reviews from customers.
When we unpacked the lithium pack we were immediately impressed by the difference in quality (just externally). I had heard many good things about the lithium packs, so I was eager to test it out. While we have only had it for about 5 months, it has been holding up incredibly well. We have noticed a marked increase in the cleaning quality as well. This could be for a variety of reasons, but is likely because our Roomba 770 can make more persistent passes over our floors.
