When it comes to energy performance, lithium-ion batteries are top performers. Compared to traditional lead-acid batteries, which hold between 50 to 100 Wh/kg, lithium-ion batteries boast an impressive range of 260 to 270 Wh/kg. In addition to being rechargeable, lithium-ion batteries have exceptionally long lifespans, lasting up to 10 times longer than their lead-acid counterparts. Unlike other batteries that struggle in extreme temperatures, lithium-ion batteries are relatively tolerant to varying conditions.
