LED lights require a stable and consistent power supply to operate efficiently. When choosing a battery for LED lights, consider the following factors: Energy Density- Opt for batteries with high energy density, as they can store more energy in a smaller and lighter package. Making them suitable for portable and space-constrained LED lighting applications. Lifespan- Consider the battery's lifespan and the number of charge-discharge cycles it can endure before its capacity significantly degrades. Longer-lasting batteries will result in reduced maintenance and replacement costs over time. Self-Discharge Rate- Look for batteries with a low self-discharge rate, which means they can retain their charge for longer periods without frequent recharging. This feature is essential for LED lights used in intermittent use scenarios.
