What Are the Best Types of Batteries for the Yongnuo YN660 Flash?
The best batteries to use on the Yongnuo YN660 Flash are:
- NiMH Rechargeable Batteries: Nickel-Metal Hydride (NiMH) batteries are highly recommended for the YN660 due to their ability to provide a consistent power output and rechargeability.
- Alkaline Batteries: Alkaline batteries can be used as a convenient option for powering the flash, but they typically have a shorter lifespan compared to rechargeable alternatives.
- Lithium Batteries: Lithium batteries offer a long shelf life and high energy density, making them a powerful choice for the YN660, although they are usually more expensive than other options.
- Hybrid Rechargeable Batteries: Hybrid batteries combine the benefits of NiMH and alkaline batteries, providing good performance with lower self-discharge rates, making them ideal for high-demand flashes like the YN660.
NiMH Rechargeable Batteries are a popular choice because they can be recharged multiple times and maintain their voltage levels better than alkaline batteries, ensuring that the flash operates at optimal performance during shoots.
Alkaline Batteries are widely available and can be used in a pinch; however, they may not deliver the same level of performance as rechargeable options, leading to quicker depletion during extensive use.
Lithium Batteries are known for their high capacity and longer life, which can be beneficial for photographers who require reliable power for extended sessions, although the cost factor may deter some users.
Hybrid Rechargeable Batteries are an excellent compromise, providing the rechargeability of NiMH with the low self-discharge rates similar to alkalines, ensuring they are ready to go when needed without losing power quickly in storage.
Why Should You Choose NiMH Rechargeable Batteries for Yongnuo YN660?
You should choose NiMH rechargeable batteries for the Yongnuo YN660 because they provide a combination of high capacity, consistent voltage output, and environmental benefits compared to disposable alkaline batteries.
According to a study published in the Journal of Power Sources, NiMH batteries offer superior energy density and can be recharged hundreds of times, making them more cost-effective and sustainable over time (Huang et al., 2022). This longevity means that photographers can rely on them for longer shoots without needing to replace batteries frequently.
The underlying mechanism behind the performance of NiMH batteries lies in their chemical composition and design. NiMH batteries maintain a stable voltage throughout their discharge cycle, which is crucial for the consistent performance of devices like the Yongnuo YN660 flash. This stability helps ensure that the flash fires at full power without significant drops in intensity, unlike alkaline batteries, which can experience a decline in voltage as they deplete, leading to inconsistent performance and potential missed shots.
Additionally, NiMH batteries have a lower self-discharge rate compared to standard alkaline batteries, meaning they retain their charge for longer periods when not in use. This characteristic is particularly beneficial for photographers who may not use their flash regularly, as it ensures that the batteries are ready to perform when needed. A study by the Battery University highlights that NiMH batteries can retain up to 75% of their charge after a year, while alkaline batteries can lose significant capacity in the same timeframe (Battery University, 2021).
What Advantages Do NiMH Batteries Offer for Yongnuo YN660 Users?
NiMH batteries provide several advantages for users of the Yongnuo YN660 flash.
- Higher Capacity: NiMH batteries typically have a higher capacity compared to standard alkaline batteries, meaning they can hold more charge and provide power for longer periods, which is essential for high-demand devices like the YN660 flash.
- Rechargeability: One of the main benefits of NiMH batteries is that they are rechargeable, allowing users to save money over time and reduce waste, as they can be reused multiple times without needing to purchase new batteries frequently.
- Consistent Performance: NiMH batteries provide a more stable voltage output throughout their discharge cycle compared to alkaline batteries, ensuring that the Yongnuo YN660 maintains consistent performance and brightness during use.
- Low Self-Discharge Rate: Many NiMH batteries are designed with a low self-discharge rate, meaning they can retain their charge for extended periods when not in use, making them ideal for photographers who may not use their flash regularly.

Are Alkaline Batteries a Viable Option for Yongnuo YN660 Flash?
The best batteries to use on the Yongnuo YN660 flash include alkaline batteries, but there are other options to consider as well.
- Alkaline Batteries: Alkaline batteries are widely available and offer decent performance for short-term use in devices like the Yongnuo YN660 flash.
- Nickel-Metal Hydride (NiMH) Rechargeable Batteries: NiMH batteries are a popular choice for flash units due to their higher capacity and ability to be recharged multiple times.
- Lithium-Ion Batteries: Although less common for the YN660, lithium-ion batteries provide a stable voltage output and can deliver high performance for demanding applications.
- Nickel-Cadmium (NiCd) Batteries: While NiCd batteries are rechargeable and can perform well, they are generally less favored due to memory effect and environmental concerns.
Alkaline batteries are a traditional option, offering a voltage of 1.5V and are suitable for users who need a quick, one-time use solution. However, they typically have a shorter lifespan in high-drain devices like flashes, resulting in reduced performance and quicker depletion.
Nickel-Metal Hydride (NiMH) rechargeable batteries are often considered the best option for the Yongnuo YN660 flash due to their higher capacity (typically around 2000-2500mAh) and ability to be reused, making them cost-effective and environmentally friendly over time. They also maintain a more consistent voltage throughout their discharge cycle, providing reliable performance for extended shooting sessions.
Lithium-Ion batteries, while not standard for flash units, can be advantageous due to their lightweight nature and high energy density. If compatible options are available, they can provide significant power for longer durations, ideal for professional use.
Nickel-Cadmium (NiCd) batteries are another rechargeable option that can handle multiple charges but have fallen out of favor due to the memory effect, which can reduce their capacity over time. Additionally, environmental concerns regarding cadmium make them less desirable compared to other battery types.
What Performance Limitations Do Alkaline Batteries Have for Yongnuo YN660?
Alkaline batteries have several performance limitations when used in the Yongnuo YN660 flash, which can affect its efficiency and usability.
- Limited Cycle Life: Alkaline batteries have a relatively short cycle life compared to rechargeable options, which means they will not last as long when used in high-drain devices like the YN660.
- Inconsistent Voltage Output: As alkaline batteries discharge, their voltage drops significantly, which can lead to inconsistent performance in the flash, causing longer recycling times and reduced power output.
- Temperature Sensitivity: Alkaline batteries perform poorly in extreme temperatures, which can limit their effectiveness in various shooting conditions, especially in colder environments where flash usage might be frequent.
- Not Rechargeable: Unlike NiMH or Li-ion options, alkaline batteries are single-use, resulting in higher long-term costs and increased waste, making them less environmentally friendly.
- Lower Current Output: Alkaline batteries cannot provide the high current needed for rapid flash firing, which can lead to slower performance during burst shooting and may not meet the demands of a professional photographer.
Each of these limitations can significantly impact the performance of the Yongnuo YN660 flash, making it less effective for serious photography applications.
