What is the life of these batteries? How many times can I recharge them and use them?

I put them in solar lights with rechargeable capabilities. So far, after 10 months, They still go strong. Sorry, my application is not as yours.

A charge doesn't last as long as for regular batteries. But, they last many years and can be re-charged numerous times.

I replace them out of habit every 6-8 months. When new and fully charged they will run for a couple of days in normal use; when streaming from my BT player or TV they last through the day I'd say 8-12 hours. I have rexton cobalt 16 rechargeable, put them in charger at end of day, and they are great.

Recharge these anytime. In fact, best to NOT let these run down entirely, as these (unlike Ni-Cad) have no 'memory.' Mainly don't overcharge. These take about a 2 hour charge, and overcharging in an attempt to bring them up to full capacity cause battery 'stress.' You can get the full, more scientific answers to your questions if you Google. Also, remove from charger after charging.

I would do one of two things. Charge them for 24 hours. Or send them back. Mine only lasted about 3 charges. That still put them roughly the price of a good disposable battery, but these are not high quality.

There's no real way to tell, and they don't have a set life span. After some time they will simply hold less and less of a charge, and they will need to be recharged more quickly and frequently. This is why I recommend the Nikon branded battery - the unbranded batteries I've owned all suffer from this problem very quickly.

I really don't know but it's not worth buying. They may last 3-5 times after use. And I think I'm being generous by saying up to 5 times.

They should theoretically last longer. They have no safety issues that I know of. I've used them as backup batteries. The key spec is the voltage, which is the same as the Sony original, so it is compatible.

I replaced them once. I purchased a pack of replacement batteries on Amazon.

I just plug the batteries in for around 8 hours and use em. It works well for me. I hope this helps. I had also purchased new batteries and I charged them overnight the first time. GOOD LUCK

As a general rule, I would try and charge the battery at least once every 30 days, but not more than 60. The longest I have let my battery be stored between uses is about two weeks, and the batteries never lost their charge. I really like these batteries as they last longer than stock batteries.

I do not believe they have a specific warranty, but packaging says they can be recharged 1,000 times. I can tell you I purchased mine last October, have recharged them over and over and they are still going strong.

It can take 5-24 hours of initial charge time for these (depending on how big the battery is) and the manual for the unit I have says "for best performance, recharge at least every 3 months or after each use." The recharge time after that first one depends on how long it's been and how drained the battery is possibly talking another 24 hours.

Many. Very many. I have recharged 20 plus times and still working. They only last 15 to 20 minutes however.

I've had them HOLD there charge for 4 months of non use! up to 2 months of off and on use and for at the irish fest shooting and video taping 2 - 4 hours depending on how hard I'm going They do hold up well I cannot complain! Those batteries that only cost a few dollares and ya I've tried them! NO.....don't hold the charge for long and don't last that long either. I've had the cheapies go in 2 - 3 years you know freshly charged and Dead in 30 min.

These batteries have a 48 month life expectancy. I know batteries from sams club are not the best. Were putting distilled water in the batteries. please check out my website: txgolfcartrepair.com

They last quite a long time, actually. I use NiMH rechargeables, and it's usually several months between recharges.

We have ordered those batteries several times and have had no problems. They seem to last 8-10 days.
