Do I need a special charger for a 12V lithium battery?
You can charge a 12V lithium battery without a specialized charger, but if you value safety and longevity, use appropriate equipment. You can use a standard Sealed Lead-Acid (SLA) charger to charge a lithium battery, but only if it does NOT have a desulfation mode, as this will be harmful to lithium batteries. You will have to monitor the charger and take it off to prevent lithium battery overcharging.
You will want to use a charger designed for lithium battery chemistry for best performance as it will take care of the unique charging characteristics and requirements of lithium batteries. This will improve the battery charging and increasing the charging efficiency.
Finally, keep your lithium battery healthy by checking the voltage in 3-4 month intervals and especially while the battery is inactive. If the voltage is low, charge it again. This will prevent deep discharge, which can be harmful to the battery. Be sure to follow the manufacturer’s recommendations while charging lithium batteries.
Generally, it’s possible to use a standard SLA charger for a 12V lithium battery, but there is a consideration. The charger must not have a desulfation mode which is a feature used for lead-acid batteries. Desulfation can be harmful to lithium batteries. Also, make sure to verify that the voltage and current settings on the charger match the lithium battery specs to ensure there won’t be any issues. Ideally, you should purchase a lithium battery charger which will be designed to lithium battery charging profiles and best improve the battery performance.
How should I store my LBXR20 battery to keep it in top shape?
Treat it right, and it’ll last for years. A good place to store the battery for long-term charging will be in a cool compartment, with a temperature of about 50-77°F (10-25°C) and a charge of 40-60%. Do not store the battery for a long period of time fully discharged or fully topped off. You should also check the voltage every 3-6 months with a multimeter, and the battery should be in the 18-20V range. Recharge it if the battery drops below 16V to prevent deep discharge. Keep the battery away from high and extreme cold temperatures. Keep it away from extreme cold or heat. Keep the battery near metal objects to prevent shorts. While the on-board electronics will keep it from being overloaded, good habits will further extend the battery life. Refer to relevant guide here: What To Know About Black And Decker Battery Care?
What if my LBXR20 won’t charge or shows a flashing red light?
A flashing red light on the charger usually signifies a problem, such as a high or low temperature battery, a temporary overload, or a faulty battery. First, try to unplug the battery and let it rest for 15-30 minutes. After this time, the battery should be able to recharge. Wipe the contacts with a clean, dry cloth. Test the voltage and it should be in the 18-21V range. If the voltage is low or 0, the battery will need to be replaced. Age, drops, and over-discharge are common problems. Ensure to always use the official charger, as this will avoid voiding the warranty.
