New 3.6V Li-Ion Rechargeable AA batteries from Hawk-Woods

[NathanWBS]

Hi all!

 

Just wanted to make you aware of a new product coming soon and to get your thoughts and opinions......

 

Power your high-performance devices with the Hawk-Woods AA-HP36 rechargeable lithium-ion battery. Designed for reliability, efficiency, and durability, this 1100mAh cell delivers consistent power for demanding applications.

Whether you're powering industrial tools, high-tech gadgets, or custom electronics, the AA-HP36 delivers unmatched efficiency and longevity. Reduce waste with rechargeable performance and enjoy consistent power output for your most demanding applications.

 

✅ High Capacity: 1100mAh (nominal) for long-lasting power
✅ Rechargeable & Eco-Friendly: Reduces waste compared to disposable AA batteries
✅ High Voltage Output: 3.6V nominal, great for high-power applications
✅ Fast Charging: Standard charge time under 3.5 hours
✅ High Discharge Capability: Up to 3C (3300mA max) ideal for high-drain devices
✅ Durability: 300+ charge cycles with 80% capacity retention
✅ Temperature Resilience: Operates in extreme conditions (-20°C to 60°C)
✅ Safety Tested: Overcharge, short-circuit, drop, and heating tested

 

These cannot safely be used in devices designed for standard 1.5V AA batteries (Alkaline, NiMH, or Lithium 1.5V). These batteries output a steady 3.6V until they suddenly drop to 2.5V, which can be unpredictable for standard devices (Some devices with voltage regulation might work, but they are not designed for this power input) Check your device manual states "Compatible with 3.6V Li-Ion AA" before using them.

 

 

Thanks,

Nate

I think this rules out any use in production sound equipment AFAIK.

Hawk-Woods gets points for clearly pointing that out. But I do share Johnny's concern. However, I could be missing something. Nathan, can you give us a few examples of production sound equipment that would work with, and hopefully benefit from, these new batteries?

Hi Jim,

 

The target of these batteries in particular was the Sound Devices A20-TX. In essence they are the equivalent to the Sound Devices AA lithium as well as the XTAR 14500 AA Lithium so would be compatible in the same devices as those that require the higher voltage. These would be a chunk cheaper than the Sound Devices offering (Price TBC) but a little more than the XTAR offering.

Thanks Nathan; that's a helpful reply.

Definitely awesome option for the SD wireless but wondering if there’s any chance for creating a high powered or longer lasting 1.5v rechargeable AA. While the newest NiMh AA last a decent amount, still would love to see one that lasts as long a disposable AA energizer lith. Or does science just not science enough for that to work?

This is as close as it gets right now AFAIK:  

 

User reports say they get the same runtime as Eneloop Pros, so not a big difference.

My guess is the issue is that lithium cells are 3.7V by default, and there isn't a good way to down-convert it to 1.5V without adding circuitry, which uses space and draws power ... which means the end result isn't really an improvement over NiMH.

This is my understanding as well.

 

Also, my apologies - I was not aware of the fact that these work with the SD wireless. That’s great!
