Before changing the battery, it is important to know if you’re old battery is still efficient and has some life left. Sometimes other issues like dirty air filters blockage in air pathways can be the reason behind the limited performance of your Dyson V7 cordless vacuum.

Because of the above reason, I would recommend you to 1st check your air filters, air pathways, and the unit itself.

There are many alternative non-OEM Dyson V7 battery replacements available in the market from different manufacturers. Be careful to choose from them as the performance varies differently. In this case, I would recommend you to first check the reviews both positive and negative and decide accordingly. Also, take note of how much is the capacity and discharge current of the new battery.

Sometimes customers complain about low performance in boost mode when they choose batteries from another manufacturer. That is why it is important to check the reviews where people are mentioning performance in boost mode end of course check if the replacement battery is compatible with your Dyson original battery charger.

Another important point to note here is that a high-capacity battery doesn’t mean it is good. Often high capacity means low to medium discharge current, this decreases the performance in boost mode.
