Anyone using an mdc with the keeppower batteries. My may concern is the extra length may cause problems. Either by putting to much stress on the springs or causing the springs to become problematic if switching back to standard cr123a batteries after prolonged use of the longer rechargeables. If you get my drift.
 
They work great. I use them in my MDC all the time. Battery life is a bit reduced versus primaries (about 5 hours total runtime on medium), but nice to always leave the house with a fully charged battery, and not have to buy more primaries.
Oh, the longer length does not seem to have caused any permanent compression of the springs and primaries still work fine as well.
 
You can't hurt the spring. It's there to take up space before the driver and move current.
 
If your spring ever gets compressed just use some needle nose pliers to stretch it back out. It is very tough.
