I use my batteries in digital road flares. Since the flares are only used when there's an accident, I haven't had the chance so I went ahead and tested the batteries on one flare setting the it on rotating, constant on, and it lasted more than 14 hours. (Three batteries per flare). Since they are stored in the vehicle, I have set a reminder on my phone to recharge the batteries every 3 months. I'll be testing again on the 1st, 3 month period prior to recharging to see how much power is still left in the battery (how long the flares light). So far I am pleased. I did try another brand but their batteries even when fully charged would not even light the flare. Some batteries just will not work.
