150 charging cycles in 31 days... How do you manage to recharge these FIVE times a day?? I'd have to think that you have 2 sets, or 2 big-batt PVs, so you're recharging batteries 10 times a day?I received 4 Tenergy RCR123A 3.0v 750mAh batteries on August 26. ... That's after maybe 150 charging cycles.
