I have a Rayovac PS4 one-hour charger. Is one hour too quick of a charge time? Will it (noticibly) degrade the lifespan of my batteries? Should I look into buying a 4-6 hour charger instead?

I also have a 15 minute charger. I'm not going to wait an hour much less 4-5 hours. Get a quality charger and you should have no problems.

It really depends on your needs. The quicker the charge, the less cycles you'll get out of your cells. I charge my cells between .5C and 1C. Charging with the 15 minute chargers don't damage your cells (unless they "cook" them), you'll just get fewer cycles.

Do you have any idea (roughly) what the amount of cycles is that you get from a good 15 minute charger verses a 4-5 hour? Are we talking something significant like50% less from the 15 minute charger? I have no idea what I get with my one-hour charger, but it seems like I only buy batteries about once per year. So all in all thats not bad, so I suppose I'll just continue using the one-hour charger.

In the old days a shallow long time charge was preferred to a kick up the ass heavy charge.Some would say, leave your batteries on a trickle charge when not using them.

I have 250 mA charger, and for 2600 mAh AA batteries it takes me about 14 hours to fully charge (over night). And It's the most healthiest! The slower, the better!

I must be way to impatiant. I've had my 15 minute Energizer charger and 2500 mAh batteries for about 6 months andre-charged themquite a few times and they still are goingpretty strong.I would rather buy new batteriesafter 6 monthsto a year than wait over night for my batteries to charge. IMO quicker is better,maybe not better for the batteries but betterfor me.

Usually, very quick charges also have rechargeable batteries that work with the quick chargers.

Using these quick chargers on just any rechargeables might damage the battery unless it is rated for quick charge.
