Shortened life！ 8.After using the battery and the battery is discharged, it is important to charge it in time before storage. Because if the battery is not charged in time after discharging, the low voltage protection will be activated. As a result, even if the battery is charged, it may not work properly when used again. Q&A Q: Can the battery be installed horizontally? A: Yes, the kusroie lithium battery is free from lead-acid battery safety problems such as battery leakage and battery corrosion, so it is perfectly fine to place the lithium batteries in any position. Q:When I get this lithium battery, is the power enough to use it directly? A:Our lithium battery has a factory capacity of 30%, which can guarantee your basic use at the moment. If you run out of 30% power, you can charge your lithium battery with solar panels or grid power. Q: Do I need to buy a special charger to charge this battery? A: You can use an AC to DC lead-acid charger that runs on mains power, as charging efficiency and duration are less important, it must not have automatic desulfation or equalization modes. If this is the case, do not use it because there is a risk of damage to the cells or the battery. This can significantly shorten the life of the battery. If it has a simple bulk / absorption / trickle charge profile, it can be used to charge the battery, but must be disconnected after charging and not left in trickle charge / maintenance mode. It must also have a maximum output voltage of 13V-14.5V.
