What You Need to Know About Vacuum Cleaner Batteries

A vacuum cleaner battery is a very important component of a portable cordless vacuum cleaner. If your battery pack fails quickly, even if your vacuum cleaner has the best features on paper, you will not be satisfied with your cordless vacuum cleaner.

Online stores and shops that specialize in electronic equipment or vacuum cleaner spare parts sell vacuum cleaner batteries as replacement parts. There are several things you need to know before buying cordless vacuum batteries.

Is it possible for a rechargeable vacuum cleaner battery to die?

Even when handled properly, rechargeable batteries can only withstand a limited number of charging/discharging cycles, depending on their chemistry. Batteries such as deep cycle lead-acids (these are NOT common car starter batteries) and nickel-cadmiums can endure a few hundred charging/discharging cycles.

Nickel metal hydride batteries can withstand up to 500 charging/discharging cycles, but some lithium batteries continue to function after 1000 cycles. A battery’s life span can be significantly reduced when it is not treated correctly, and it simply dies!


All batteries lose capacity after some time, but this is within certain limits, as dictated by various standards. You, the consumer, are the best tester – if your vacuum is not performing as well as when you bought it, it’s time to change the batteries.

Your cordless vacuum cleaner’s manual should always be read. The type of battery you need will depend on whether you have a handheld or backpack vacuum cleaner (or any other type of battery-powered vacuum cleaner).

  • The replacement part ID number of your battery, as well as the model of your vacuum cleaner, should be written down. You will then be able to buy the correct battery.
  • The non-OEM replacement battery packs are typically cheaper than OEM replacement batteries, but they are usually not as thoroughly tested as OEM batteries and do not perform as well as original batteries. New original battery packs can sometimes cost almost as much as a brand new cordless vacuum cleaner.
  • In these cases, it is best to buy non-OEM replacement battery packs, but read what other customers have to say about the batteries you are about to buy.
  • When non-OEM batteries get bad reviews, it is pointless to buy them. Even if it costs almost as much as a new cordless vacuum, buy an OEM vacuum cleaner battery rather than a new cordless

Batteries for vacuum cleaners: Buying Guide

In the event of a vacuum cleaner that has a battery pack composed of ordinary consumer (mostly AA or AAA) cell batteries (such as some handheld or car Batteries for Cordless vacuum cleaners), always replace all batteries (cheaper in the long run) with new ones that have the same battery chemistry.

The best batteries last longer, endure more charging/discharging cycles, and have a lower self-discharge rate. Consumer primary and rechargeable batteries used in cordless vacuum cleaners include AA, AAA, 18650, CR2032, CR123A, LR44, and many other similar alkaline, silver oxide, NiCd, NiMH, and lithium batteries.
