Vacuum cleaner battery problem treatment:
1. Before purchasing, check whether the vacuum cleaner model and connector are consistent. If the new battery cannot be identified during the initial installation, reinstall the vacuum cleaner and check whether the port is fully connected.
2. Note: After receiving the battery, please fully charge the battery before use, and charge it in time after use. This prevents the battery from continuously discharging, causing the voltage to be too low to charge!
3. Charge the robot vacuum battery for the first time. Due to the instability of voltage and current, when the battery is half charged (sometimes more, sometimes less), the robot vacuum may stop charging the battery. If this happens, don't worry, just remove the battery from the robot vacuum and recharge it. It may take several iterations for a new battery to charge for the first time. Don't worry, which is normal.
4. When the battery is in normal operation, if the battery is discharged to 5-10%, it must be shut down or recharged. If the battery is discharged to 0%, the battery will be damaged and its life will be attenuated.
5. The battery's over-current protection may be activated when vacuum is overloaded or stuck by furniture. Please turn off vacuum power button and manually move it to charger dock to reactivate the battery, and then turn on power button.
6. Remove the battery and store it for a long time. If you do not use the sweeper for a few weeks or more, remove the battery after it is fully charged and store it in a cool and dry place. When you need to use it again, install the battery and fully charge it. The battery power that is idle outside will gradually decrease. Generally, The battery can be fully charged once every 3 months to obtain good performance.
7. Battery useful Caution: 1.Don't disassemble 2.Don't dispose of in fire or water 3.Don't store above 60 ℃（140℉）3. Do not use if battery shows signs of serious bulging. 4. Do not use after the battery is immersed in water. 5 to be charged only with specified charger at 32-104℉(0-40℃).

I got 2 of these same batteries and tested both on a digital capacity tester before and after a full charge. The test results are better than I've seen compared with some other power tool batteries. They both came in with about 2.5Ah charge, and after a full charge, they both came out to be very close to 5.5Ah and around 80Wh, which although they are not the 6.8Ah rating as stated, I would qualify that as a fairly decent close considering how awful other new batteries prove to be compared to their rating nowadays. They both ran for about 4hrs 7min to 4hrs 10 minutes in my test until depleted to 5-10% of their total capacity before the discharge test was stopped from collapsing the battery to 0Vdc.So, the 2 batteries tested almost identical, the only difference being that this one costs about 39% more.I did not open these battery packs to see if they include a BMS protection circuit, and in terms of battery manufacturing quality, only time will tell their longevity and reliability.I'm not sure how the capacity rating on these batteries have been decided, I can suspect that if they are tested with a very small load, their capacity number could potentially get closer to their 6.8Ah rating, but that still doesn't help the user because that would not be anywhere close to a typical load in the real application.However, I chose to size up the load according to what battery manufacturers typically use when they rate the capacity of power tool batteries, which is a discharge rate of 0.2C (or C/5, meaning the battery is discharged over a period of 5 hours). I found that this rate is considered a standard for providing a consistent and reliable measure power tools battery's capacity, and a cordless vacuum actually falls in pretty much the same category and usage demand. Today's manufacturers take a lot of freedom in advertising their battery capacity for marketing reasons, so in order to find out how the posted Ah rates compare with the reality out there, I used a digital battery capacity tester and set it up for a C/5 discharge rate (1.36A constant load in our case) and monitored the battery until discharged down to 9V when there’s only about 5-10% of its total capacity remaining. At this point, the voltage is already past the "knee" of the discharge curve that typically occurs when the battery has around 20-30% of its total capacity remaining and when the voltage starts to drop rapidly, indicating that the battery is nearing depletion, and the tool is pretty much "dead". In real life however, these batteries are being hit much harder than my test, as vacuum cleaners generally draw their batteries down at a much faster rate and become unusable at an earlier discharge point than the one chosen in my test.
