Just for me personally, i have avoided responding to all except a few of the "can i use LR batteries on an EGO/RIVA/016...." threads. The reason is there really isn't an answer.
Will it cause a difference in the way your battery performs? The answer even to that question is way too long and complicated for most folks to even care. You have to define exactly which battery and then define what it's listed specification are to even begin to calculate what the effects of using a different load than the battery was designed to use. Just actually testing how it actually effects any of those specifications is time consuming and expensive.
I speculate that is the only reason myself and none of the other EEs here have actually done so. There are several standards for testing just the basics of battery performance so even if some real tests were actually done the results would be subjective and probably not even come close to answering the actual questions.
Just take cycle testing the battery alone under diffenent loads. Cycle testing evaluates the battery's usable number of charges & discharges. There are a hundred conditions or more that effect this test alone. Temperature, altitude,humidity,power condition and the list goes on and on. Now you have to establish what constitutes the end of useable duty. Most test standards allow the battery to continue in duty until it fails to meet 80% of its rated specifications. Then you have to include failure percentage...how many batteries must fail the test out of 100 to apply to all of them.
Now once we somehow all agreed on the test variables we can actually start the tests right....
Lets just test the smallest sample possible to get even a minimal accuracy. 1 brand, 100 batteries....ok, i'll foot the bill for 100 ego batteries to be destroyed (Not). So let's hook 'em up to some test equipment and really determine if a LR load vs the load used by the mfgr shortens their life. Now we need 200 batteries, one set for the control and one set for the LR load. (We won't even get into how we set the conditions for standardizing the load). So now we're off...
So we set up our banks of 100 cells using some expensive multi-channel testers which can create different charge and discharge profiles including pulsed inputs and loads. All the while maintaing the performance parameters like temperature, impedance, output rate and so on. Now we have to monitor and record the results. Let's say it takes takes about 5 hours minimum to completely discharge an Ego battery, and they are rated by the mfg to let's say 400 cycles.
Thats 400 cycles x 5 hours = 2000 hours, divided by 24 hours a day which is 83 days. For larger capacity batteries like the Hello 016 it would more than double to like 170 days.
I simply don't care enough nor have the time and money to do so to prove what many keep asking.
Will using a LR Atty on my ego/riva/etc "kill" my battery?
Who knows! If you want to get more heat from the same size battery then accept that any deviation from the parameters the Mfg used to test the specs of the battery will change the outcome.
Either use bigger batteries or quit worrying about it and buy some extras.
