All I have ever had is Trustfire Blues. They are only about 8 months old, I originally ordered two 2-packs from DX, one cell was DOA, they replaced it with 2 more so I now have 5. They all seem like they're lasting fine, I rotate them in a 1 cell flashlight. I have the Magicshine mounted now and the flashlight is just for backup, but when I forgot to charge the MS last week and it died on the road yesterday, the P7 with a Trustfire blue in it that was charged 6 weeks ago and has been just sitting there stepped up and ran the P7 for nearly an hour on high without trouble.
Work: the 8 hours that separates bike rides.
