do these have twice the life as the smaller 1.5ah lithium ion batters...cuz they're about twice the price, and twice the charge time

I did not actually time the life, but the larger battery is the best. I feel it is worth the extra cost.

Having used the 3.0 for a while (years) I really, really like it. It lasts and lasts. My charge time runs about 2 hours with their standard charger. You can find this battery on line discounted but it is worth it's cost. Get the 3.0, you will be glad you did. BUY FROM A REPUTABLE DEALER!

The tools work better because of higher amperage and, yes, the charge lasts much longer. I highly recommend it!

Actually that's a really good question. The answer is yes they do hold a charge for a long time. I've been able to get a couple of days out of my batteries.

they will not be on the same frequency. My friend and I bought one at same time. and we race them batteries last about 25 minutes at top speed, before needing recharging

I received charged. But I re-charged and they do last a long time compared to regular Top Brand AAA Li Ion batteries (non chargeable).

NO! They are not the 1.5 Ah batteries and the listing did not state that they aren't the current 1.5s! My batteries are stamped 2011. Seller offered a call tag to pick them up and refund my purchase price, but then I'd be out the money for shipping and have no extra battery. No joy for me, buyer beware!

They do but if your using it for a mod the MAH is to way to low that it'll die within minutes and it charges way to fast. Hope that helps

yes, they are not as good, u have less run time then the $120 each battery. If you are looking to sell it they are fine if you use it all day every day go with trojan or jazzy battery

These are facile batteries and charging is difficult to pin down. The first time I charged them it was maybe about and hour, but they were not completely drained either.They should not be over charged are over used in my experience. They get really warm in the torches and will at this point discharge rather fast. I try and watch them when charging because I really don't trust them, when the Green light comes on I take them off the charger quickly, hope this helps.. PS: this is the first time I have had all eight being in perfect working order since I started using them.

They're not necessary, no. The former is really recommended for any Lithium Ion battery for maximum battery lifespan, but it's not required and it won't hurt you to avoid it. Having read about this before, it appears that this is mostly for devices you aren't using constantly. Keeping a device at full charge for long periods is the real no-no. Short charges are bad for a battery, but we're talking roughly 5-10%. Discharging down to &gt;2% may not only not help, but in itself be bad for the battery (especially due to heat and the size of the battery). There has been talk about a memory effect, but only in the last eight months. Li Ion batteries have managed a 20 year history without significant noticeable effects of 'memory,' so take such arguments with a grain of salt.

I am only on my second season with these batteries and they charge just fine. I have about 1/2 acre of grass to cut and can cut that with 2 of these in the mower.As for how long they will fully charge, i do not know. I hope about 4 years as they are expensive right now.

Same or a few longer, they are awesome batteries and the charger is convenient, about an hour to charge, Well worth it!

I have not as yet and I basically use them every day and charge what feels like every other day. They say 10 hours and it really is at least that. I'd agree that replacing the battery is unfortunately not a likely option. The silver lining perhaps is that li-ion batteries are very good these days so with some luck they'll last several years.

Yes they do! Tested with mine. While I can't attest to the exact battery life of these compared to the Sony branded batteries, they will discharge faster.

Not sure. These batteries didn't last long after I charged them once. They seemed to last for 2 lifes the first time use and the first time charging.

I don't notice a difference as far as battery life is concerned. They work great! One thing that I did notice, the battery is hard to remove from the charging case but I have only charged the batteries a couple of times. There is a video that shows u how to remove them and l will look at that again someday.....Not a big deal.

Yes, my batteries lasted a short time also. I purchased rechargeable ones & the charge has lasted so far 4 months.

That is exactly what my cordless called for but I used these higher mH batteries and they work great resulting in longer call times. Be aware that these batteries are not OEM and the wires are a bit longer than the stock white ones but for the price and higher mH you can't go wrong. I noticed that while on a long call these batteries hold a charge with no problem, when using my old white batteries on the same length call approx 1 hour the phone started to beep notifying me that the battery was about to die but so far these new ones worked out very well. Good luck.
