Best Roomba Replacement Battery

Best Roomba Replacement Battery

iRobot is a dominant player in the robotic vacuum industry. One reason is the sheer number of parts available. The sheer number of options can be confusing, one of which is the battery.

We’ll look at the best Roomba replacement battery in this article. Note that I won’t be talking about original iRobot batteries but third party options, but I’ll link to them under each model just if you want to use OEM.

Disclaimer: iRobot recommends using original batteries for the best performance and longevity. So if you’re planning on using OEM replacements, it’s crucial to choose a reputable brand with good reviews.

How to choose a replacement Roomba battery?

Before choosing one, make sure to identify the Roomba model you have. You can find this information underneath the robot above the right wheel (check photo below).

Once you have that information, hop on Amazon, eBay, or wherever your store of preference to purchase.

1. Check the model before buying

Before hitting the buy button, make sure to check and double-check if the battery is compatible with your Roomba robot. The last thing you want is buying the wrong battery and waste time shipping it back to the seller.

I’ve listed the models each battery is compatible with, but it’s best to double-check on the merchant store itself.

2. Choose the right type

There are two types of batteries sold – a NiMH and a Li-ion battery. The Li-ion is a newer technology that takes less time to recharge and usually runs longer. It’s less prone to fading, easier to maintain, and lasts longer versus a NiMH battery.

But these are more expensive than an equivalent NiMH battery.

3. Get a brand new battery

Always opt for a brand new battery. The appeal of a renewed (or refurbished) battery is its cheaper, but its history is unknown, and for a critical part like the battery, it’s wise to spend more on a brand new component than going through buyer’s remorse.

Sparkole 5300 mAh

This option is one of the more popular Li-ion options available and one of the least expensive. With its large capacity (5300 mAh), Sparklole claims it can run for up four hours – more than any of the high-end robot vacuums like the Roomba S5 Max.

It has a 1000x recharge cycle and only a 1% self-discharge rate. The manufacturer claims it will run for up to 2 years without any issues and has a 35-day moneyback guarantee plus a 12-month limited warranty.

Melasta 5200 mAh

Another high-capacity option is the Melasta 5200 mAh. Melasta claims it will run between 1 to 2 hours on a Roomba 900 series and (up to) 3 hours on a 500, 600, 700, and 800 series.

The life cycle is impressive at 1,200 cycles with a built-in overcharge and overcurrent protection.

It comes with a 45-day money-back guarantee and a 12-month warranty.

Tenergy 5200 mAh

Rounding up the Li-ion replacement options is the Tenergy 5200 mAh. It’s the most expensive option, but it comes with some extras – 4 side brushes plus a brush cleaning tool.

However, Tenergy doesn’t specify the number of charge cycles. It comes with a 12-month warranty, but no mention of a money-back guarantee.

Powerextra 3800 mAh

One of the more popular Ni-Mh options is the Powerextra 3800 mAh 14.4V replacement battery. This model is compatible with select Roomba 500, 600, 700, 800, and 900 series robots.

Along with the battery, you’ll also get four extra side brushes plus two screws.

It has built-in features against overcharge and over-discharging. Powerextra provides a 30-day return policy plus a 12-month warranty. They did not mention any run time claims, but several consumers say it lasted up to 2.5 hours.

Please follow the recommended procedures by the manufacturer if you choose this option. This includes running it until it’s discharged completely.

Moripilot 4050 mAh

Another popular NiMh battery option in this list is the Moripilot 4050 mAh. This battery is rated at 14.4 volts and will last between 1.5 to 3 hours.

Moripilot says that battery capacity will remain at 80% after 500 cycles.

One disadvantage of using a NiMh battery is the lower number of cycles. Assuming you use this robot once a day, it will retain 80% of its claimed run time after 1.5 years.

You’ll need to charge this battery for 12 hours before initial use. As a bonus, you’ll get two extra side brushes, two screws, and a brush cleaning tool out of the box.

Authentic iRobot 1800 Li-ion

Now, let’s move to the original iRobot battery options for Roomba. First is the 1,800 mAh Li-ion battery.

This model is compatible with a wide range of Roomba models, including the 614, 675, 690, 890, and 960. Also, it’s the default battery you’ll get from the newer batches of the 675, 690, and 960.

Don’t let the low capacity discourage you from getting this model. It’s the safest alternative if you don’t want to risk damaging the robot with an inferior replacement battery.

XLife Extended Life Battery

XLife is another option if you want a high-capacity NiMH replacement battery from iRobot. Unfortunately, it’s a NiMH battery, but an upgrade from the older NiCd used by older Roomba models.

It’s a 3000 mAh NiMH battery, but iRobot doesn’t specify how long it’ll run. That would depend on the Roomba model.

Also, it’s compatible with Roomba 500, 600, 700, and 800 series models, except for the 690 and 890.

caSino187 Replacement 1800 mAh

We’ll look at the caSino187 replacement batteries for the E and I-series robots to round out this comparison.

Since these models are relatively new in the market, there isn’t much in terms of replacement battery options.

The good news is, the E and I-Series robots utilize iRobot’s latest Li-ion batteries, so it should last for several years.

Can Roomba battery be replaced?

Yes, the battery of all Roomba products is replaceable. You can find batteries even for ancient models like the 500 series on Amazon and eBay – that’s how popular iRobot products are.

One thing I like about Roomba products is the straightforward approach in replacing the battery.

For older models like the 690 or 675, you’ll have to remove the entire base plate to gain access to the battery.

Some variants like the 980 or 960 are easier to replace since you only have to remove the battery cover.

How to replace a Roomba battery?

The excellent news is Roomba batteries are easy to replace. It involves removing a few screws then taking off the base plate or battery cover to access the battery.

I’ve written guides based on the model. You can check these below.

The steps of the Roomba 690 are similar to the 614, 675, and other 600-series robots since all have the same bolt pattern and battery placement. Ditto with the 980 being similar to the 960.

How do I know if my Roomba needs a new battery?

There are some telltale signs of a dead Roomba battery – shorter run time than usual, indicator lights not illuminating, and low pick up.

If you encounter any of these signs, try to reset the battery by pressing the Home, Clean, and Spot buttons simultaneously, then charge the robot for up to 72 hours.

For owners who have an older Roomba like the earlier generation 650 series with the Ni-Cad batteries, you may want to upgrade to Li-ion batteries if the batteries are bad.

Roomba battery maintenance tips

While replacement Roomba batteries are not expensive, the costs will add up if you replace them often.

To ensure longevity, these are some of the best practices.

  1. Use the robot often: iRobot recommends using it daily to improve service life.
  2. Keep it plugged in: Make sure to keep the robot on the charging dock. These batteries have a built-in system that prevents overcharging and slows down to a trickle if it’s full.
  3. Clean the robot regularly: Dirty components not only increase wear but forces the robot to work harder, thus consuming more battery. Make sure to have a schedule for cleaning the robot’s various components.
  4. Charge the robot ASAP: Don’t leave the robot undercharged or drained. Doing so will accelerate wear and damage the battery. Charge the robot after every run and keep it fully charged.
  5. Remove the battery for extended idle periods: If you’re going on vacation and not using the robot for months, remove the battery from the robot. Another option would be turning off the robot, but I prefer removing the battery to be sure it doesn’t fully discharge. iRobot recommends detaching NiMH batteries from the robot for extended storage.
  6. Fully charge every six months: Piggy-backing on number 5, recharge the battery every six months to ensure optimal performance.
  7. Read instructions carefully for initial charge: Some manufacturers require you to charge and discharge two to three times fully during the initial phase. The process will be different depending on the manufacturer. The point is to read the manual carefully before using it.

How much is a Roomba battery?

The cost will depend on the model and if you’re purchasing a Ni-Cad or Li-ion battery. Batteries for newer options like the E5, I7, or S9 will cost more.

For older options, like the 600 series, OEM replacement batteries will cost less. These will usually cost below $70 for Li-ion variants, and at times under $30 for Ni-Cad. But it’s just a ballpark figure, so better to check the links to see the actual prices.

Roomba battery reset

One way to revive a dead battery is by doing a battery reset. For older models like the 600 and 900 series, it involves pressing the home + clean + spot buttons simultaneously for a few seconds.

Pressing these buttons will reset the robot into its factory settings. You’ll have to press the spot + home buttons to activate WIFI once again.

If resetting doesn’t work, it may be time to buy a new battery.
