Dyson V7 Battery Replacement
Dyson V7 cordless vacuums rely on their built-in batteries to provide power during cleaning.
When it was introduced, the Dyson V7 was known as one of the best cordless units on the market. Even today, with its 100 Air Watts, it is one of the stronger, mid-range, cordless vacuums, comparable with many newer models.
If You have a Dyson V7 cordless vacuum and it is working well, except for the battery, getting a new battery can prolong the operating time of your unit for a few more years.

Dyson V7 Battery Features and Specifications
Dyson V7 vacuum cleaner is a cordless unit that features maximum suction of 100 Air Watts in Boost mode which may last up to 6 minutes with a brand new, fully charged OEM battery.
Also, normal vacuum mode may last up to 30 minutes.
Dyson V7 OEM battery features six lithium-ion 3.6V cells connected in series for a total of 21.6V and can be recharged using the original battery charger while the unit is in the wall docking/charging station, or by directly plugging the charger into the battery.
Dyson V7 features an intelligent charger, allowing the users to place the unit on the wall docking/charging station and forget about it until the next cleaning task.
Because of the Boost Mode, the Dyson V7 battery consists of medium-capacity, high-discharge cells that can withstand high discharge currents well - the Dyson V7 OEM battery can easily last up to 4-5 years, sometimes even more.
Note: In order to prolong the battery life, don't use Boost Mode unless it is actually needed.
Dyson V7 cordless vacuum doesn't feature a snap-in battery - the battery is semi-permanently fixed into its position via 3 (three) screws.
New Dyson V7 Battery - OEM or Non-OEM Battery?
When looking for a new battery, first consider checking the unit, check the air pathways and especially air filters - sometimes blocked air pathways and dirty air filters drain the battery faster, while the battery itself is still good.
If the battery needs replacements, go either for the original (OEM) Dyson V7 battery or choose one of many Non-OEM Dyson V7 batteries on the market.
Personally, the OEM battery is more expensive, but it is tried and tested technology that comes with a 1-year limited warranty.
If You decide to go for a Non-OEM Dyson V7 battery replacement, go for the brand and model that features many positive reviews, especially by the people using Boost Mode often.
Also, the Non-OEM Dyson V7 battery must be compatible with Dyson's original battery charger.
While the original Dyson V7 battery features ~3.5h charging time, if You go for the new battery with higher capacity, expect a longer charging time.
Note: high-capacity, low to medium discharge current cells don't withstand too well high-discharge currents of the Boost Mode - if You use Boost Mode often, go for the ~4000 mAh (4.0 Ah) Dyson V7 battery replacements since 5000 mAh (5.0 Ah) cells are most probably low-discharge high-capacity cells. Or simply go for the Dyson V7 OEM battery ...
How to Replace Dyson V7 Battery
When a new battery arrives, the actual replacement is simple and straightforward.
The replacement procedure is very simple:
- locate and remove three screws holding the battery: one is above the charging port, the second and third screws are below the battery,
- detach the old battery from the vacuum,
- slide the new battery in its position,
- screw back the three screws which will fix the new battery in its position.
And that's all - be sure to recycle the old battery properly.
After replacing the old battery, recharge the new battery before the very first use - lithium batteries are for safety reasons transported in semi-charged condition.
Long Story Short: A new battery can give a new life to your "aging" Dyson V7 cordless vacuum - if the vacuum itself is good and the battery is failing, why spend more money on buying a new vacuum, when the "old" vacuum actually works and it works well.
Should You choose a non-OEM Dyson V7 Battery replacement, again, go for the brand/model with many positive reviews, which is already tested by countless users before You - if the new battery worked for them well, it will most probably work well for You too ...
