Introduction

When it comes to enhancing the performance and longevity of your camera flashes, the choice between rechargeable and single-use lithium AA batteries can significantly impact your photography sessions. This article explores the experiences of seasoned photographers and provides a detailed comparison, focusing on the performance, cost-effectiveness, and reliability of both types of batteries.

Performance and Reliability of Rechargeable AA Batteries

Experiences and Observations

In a recent conversation, a seasoned photographerstrongK33F/strong shared his experiences using rechargeable AA batteries in Nikon Speedlights SP500. He used Eneloop batteries, a popular rechargeable option, and found that they have several advantages over single-use lithium AA batteries:

The Eneloops operate very similarly to single-use batteries in terms of performance, with no discernible difference in recycle times or output when powered by these rechargeables versus single-use batteries. The Eneloops maintain their charge well beyond reasonable expectations, ensuring consistent power during photography sessions. There are minimal concerns about the initial lower efficiency of Eneloops, as they pay for themselves over time with significant cost savings.

K33F's experience suggests that rechargeable batteries, though initially more expensive, offer substantial long-term benefits, particularly for users who frequently use their camera flashes.

Limitations of Rechargeable Batteries

Key Takeaways from K33F's Insights

K33F also discussed the challenges of using rechargeable batteries in older or less voltage-sensitive systems, noting that the fully charged output voltage of a 6V pack would only be 4.8V, potentially misleading the onboard computer into thinking they are flat. However, with a bypass, these batteries can deliver a very healthy current and shorter recharge times.

He also mentioned that rechargeable batteries can fail suddenly and without warning, reaching terminal discharge voltage immediately, which can be problematic during photography sessions.

These limitations highlight the importance of compatibility and proper use when employing rechargeable batteries in camera flashes.

Comparison and Recommendations

Cost-Effectiveness and Practicality

Another photographer shared his experience with using rechargeable NiMH and NiCad batteries, emphasizing the initially challenging performance but the long-term benefits:

NiMH and NiCad batteries, while not as efficient in a 6V pack, can deliver a healthy current and shorter recharge times in less voltage-sensitive systems. However, these batteries can fail suddenly, posing risks during critical moments in photography.

Based on this, the recommendation is that if you use your flash a lot, using rechargeable AA batteries is the only way to go. A photographer named 'K33F' suggested purchasing two sets of NiMH batteries, consisting of 4 rechargeables and a charger per set, which can save hundreds of dollars each year on non-rechargeable AA batteries.

In conclusion, the decision to use rechargeable AA batteries in camera flashes is a balance between initial investment and long-term cost savings and reliability. Whether you choose Eneloop or other rechargeable options, the benefits of reducing waste and saving money make it a worthwhile investment for frequent flash users.
