Thought I would share this with the group. I picked up the MAHA MH-C204F Charger & Battery Kit for 49.00. The Kit included the MH-C204F charger and 8 2200mAh NiMH AA rechargeable batteries, 2 battery carrying cases, AC and Car Adapter.
I am testing these batteries with an LSH-P #118 with the older style twisty 2AA-battery power pack and using the clicky for the 123As. All tests are continuous burns from start to finish. (Finish = first time to go into moon mode) I am setting the LSH-P in a small check box angled up to maximize airflow around the body of the LSH-P. (Head up)
I did the burns with the 123A to give you a direct relationship as to what you could expect if you know what your run time is with these 123A batteries with your individual light.
First Set of batteries - 2200mAh NiMH (Conditioned two times before first test)
1 hour 59 Minutes. First test
1 hour 55 Minutes. Second test (After recharging)
Second Set of Batteries - 2200mAh NiMH (Conditioned two times before test)
2 Hours 8 Minutes
Third Battery - Surefire 123A
1 hour 11 Minutes
Fourth Battery - Sanyo 123A
1 hour 9 Minutes
Conclusion
MAHA MH-C204F Charger and batteries – Overall I am impressed with this Kit. The performance of the 2200mAh NiMH when directly compared to the 123As seems to be inline with what you would expect. I am referring to the burn time ratio compared to the 123As and not the actual run time. As you can see you are getting about 50 more minutes of burn time when compared to the 123As. Projecting this out if you were getting 2 hours with the 123As, I could see you getting almost four hours with the 2200mAh NiMH.
LSH-P - I actually expected longer burn times from all of the batteries. I can't explain why the performance is somewhat lower then expected. The one thing that I noticed is with the 123A burns the light got really hot at first. (Almost to hot to handle) The light did cool somewhat for the remainder of the burn. (Last 25 minutes or so). The 2AA configuration got warm but not as hot as the smaller 123A clicky. (I'm sure the larger surface area has a lot to do with this) The light it self was noticeable brighter during the first part of the burn in all of the tests. When I first tested the first set of 2200mAh NiMH I felt like I might have had a bad battery due to burn time so I did a second burn test with two other 2200mAh NiMH batteries. I also thought that I would get about 2 hours out of a Surefire 123A that's why I did a second burn with the Sanyo 123A. It's my understanding that a continuous burn will sometimes yield a shorter life on a battery but the actual burn time surprised me.
I hope you find this information useful in some way. I would like some advice if anyone has any on how to get a longer burn time. The threads seem relatively clean and lubed properly. Given the high heat and brighter light at first, I'm wondering if there might be a regulation issue with the light. Any thoughts on this Peter would be appreciated.
Just as a side note: Given the amount of heat generated by the 123As on such a small light I can see where Peter is going to have a challenge with the LS5. I am soooo looking forward to getting one.
