It’s a common misunderstanding that lithium-ion batteries for data center and UPS applications are prohibited in some large cities such as San Diego and New York City. The current laws permit stationary storage battery systems, which applies to UPS, provided they are UL listed and meet the applicable sections of the NFPA fire codes.

AAA batteries are not typically lithium-ion batteries. However, rechargeable lithium-ion batteries are available in standard sizes like AA and AAA, but only a few Chinese companies manufacture them1. Lithium-ion AAA battery size has been technically named as “10440” to separate it from other AAA batteries since its nominal voltage is 3.7 volts2. Some popular applications of the Lithium-ion battery packs are digital cameras and laptop computers2.

A 12V lithium battery fully charged to 100% will hold voltage around 13.3V-13.4V1. A fully charged 12-volt battery should show a reading of 12.8 maximum2. A fully charged 12V lithium iron phosphate battery should read between 13.4 Volts and 13.6 Volts at rest3. The voltage of a 12 volt lithium battery pack fully charged is 14.6 volt4. The charging voltage for a 12V LiFePO4 battery is 14.2-14.6V, with a float voltage of 13.6V (or disabled)5.

For a 36V golf cart, you might want to consider a lithium iron phosphate (LiFePo4) battery. It is non-explosive, safer, maintenance-free, smaller, and lightweight, which means more mileage, better acceleration, and more run time and savings down the line1. The InSight series by RELiON is a good option for a lithium golf cart battery2.

Once charged, disconnect the charger and let the battery rest for about two hours. This allows it to cool down and stabilize. Then, connect your battery to a device that will steadily drain it, like a light bulb. Confirm the device’s power requirement matches your battery’s rating to avoid potential hazards.

Lithium-ion batteries are not yet considered fully "environmentally friendly," but they have advantages over fossil fuels. While they facilitate renewable energy and produce fewer carbon emissions, the process of obtaining lithium through mining is destructive to the environment12. However, they can store energy from renewable sources and support the transition to a cleaner energy grid3.
