I would think MagicShine would inform anyone getting the replacement battery if there were going to be issues with the original headlamp unit and the supposed runtimes.
I've just received my a replacement Geoman Gear battery for the defective new battery when I bought a new MJ808 light set two weeks ago. This time the new battery did not arrived DOA and I was able to charge it for an hour when the green light came on the charger. I cannot say if this is the same pack that will be the replacement pack for the thousand of recall packs but I believe it will be. Here are some data of the battery pack running with an older (1.5 year old) MS900 light.
The battery stopped charging at 8.46 volts.
The new battery OCV was 8.26 volt after disconnecting from the charer
The test is done with the light on HI mode and volt was check under load with the light on Hi.
after 15min 7.95v indicator light was green
after 30min 7.52v indicator light was green
after 60min 7.24v indicator light was green
after 90min 6.99v indicator light was green
after 105min 6.91v indicator light turned
red
after 120min 6.83v indicator light was red
after 150min 6.70v indicator light was red
after 180min 6.47v indicator light was red
I stop the test at 3hrs. The light was still on and the battery have not shut down by itself. I stop since it was only rated for the three hours and no sense in me running it down.
In comparison with the old stlye battery, the indicator light on the light head of the old lamp with the old battery does not turn red until the last 10 minutes when the old battery were new. It seem these new battery run on a lower voltage for a longer duration but has the same Amp hr capacity. The newer light head has three colors for the indicator: Green, Orange and Red. The indicator will remain in the Orange during the time when the old light head will be showing red. I have to agree that the indicator light will have to be ignore if you are using the old light head unit with the new battery.
