Tenergy Centura 4000mAh NiMH Rechargeable C Batteries (48 Pack) - Low Self Discharge, Pre-Charged for Flashlights, Toys, and Emergency Devices

I own a lot of NiMH batteries ... mostly AAs & AAAs, but I do have a fair amount of C, D and 9V. Tenergy is one of my favorite brands - they tend to provide a great price vs. performance quotient and the LSD - Low Self Discharge - are great to put into items (like radios) that you don't use often, yet you want to ensure that when you do use them they (a) have a charge; and (b) retain power so you don't lose your preset stations and/or clock/timer.From my experience, I would rate these 4000 mAh Tenergy LSD C and the 5000 mAh EBL NiMH C cells as the best in class (of all NiMH C cells). You cannot go wrong with either - and both greatly outperform the Energizer rechargeable NiMHs.Also, don't underestimate the importance of having a good quality Battery Charger. I typically use a Tenergy T9688 Battery Charger & I have an identical C. Crane-branded model as the T9688. If you don't have a decent charger, you won't get satisfactory performance from ANY NiMH battery! Choose a charger that (1) Reconditions batteries; and (2) Can identify batteries with bad cells that need to be discarded (recycled).
