Compatible With Only fit for V8 SV10 Series, Can't fit for V6 V7 V10 V11..., please check your model before ordering Battery Maintenance Please don't use the vacuum cleaner when charging the battery. Please don't stay battery on the charger unless in charging; Keep the battery Clean before charging, and Cool down the battery before recharge it. Don't leave the battery dormant for long periods of time, We recommend using the battery at least once every two to three weeks. Store it in a clean, dry, cool place away from heat and metal objects; Ni-Cd, Ni-MH, and Li-ion batteries will self-discharge during storage; remember to recharge the batteries before use. Because the battery has overheating safety protection, avoid recharging immediately after a full discharge, otherwise, it will give a red light alarm and stops running. Always remove the battery pack from your tool when you are assembling parts, making adjustments, cleaning or when not being used for an extended time. It will heat up just after using the battery. This is a normal phenomenon. Please do not charge it immediately, otherwise, it will affect the life of the V8 battery. Note: Wait for 15-30 minutes to cool down before charging.

Original battery had reduced battery life. ### ⭐ No longevity *by C***H on May 18, 2024* Worked great for a little while then stopped working after 5 months. The seller said it was still under warranty and that I would get a replacement through Amazon. That wan't true. Luckily Amazon worked with me and gave me a refund. I would not recommend buying this battery. ### ⭐⭐⭐⭐⭐ Great replacement battery for a Dyson cordless vacuum cleaner *by F***R on September 22, 2024* This battery was worth every penny. It is so much better than the battery that comes with it our Dyson. Now we don’t run out of charge. Our house is small so there was no reason for that. Now we are happy with our Dyson finally. But if you want a light, go order those little green lights that stick on to the side of your vacuum head. They’re rechargeable . They are pretty cheap and you can see all you’re vacuuming up. Now you don’t need to buy the most expensive model of Dyson. You’ve just upgraded it twice for very little.
