Likewise, is NiMH better than lithium ion?
NiMH batteries offer a higher capacity than Nicad batteries, and less capacity than Li-Ion. They are nearly twice as heavy as Nicad batteries. They also don't have a memory effect. They are very similar to nicad when it comes to charge and discharge characteristics, and are safer than Lithium ion with thermal runaway.
One may also ask, do lithium batteries last longer than NiMH? Power: Li-ion and NiMH batteries can actually hold a similar amount of power, but the lithium-ion cells can be charged and discharged more rapidly. But manufacturers are working to improve the chemistry to make the Li-ion batteries last as long as the vehicles they power.
Likewise, are NiCad and lithium ion batteries interchangeable?
Answer: It is not the same, but they are interchangeable. The PC18BL is a lithium-ion battery and the PC18B is a NiCad battery. They use the same chargers and will work on the same tools.
Which lithium battery is the best?
The most economical lithium-ion battery in terms of cost-to-energy ratio is the cylindrical 18650 (size is 18mm x 65.2mm). This cell is used for mobile computing and other applications that do not demand ultra-thin geometry. If a slim pack is required, the prismatic lithium-ion cell is the best choice.
