What is the main difference between these NiMH 9v and LiON 9V with higher mAh? Would a LiON 9v rated at 600mAh last 3x's as long per charge? Thanks

One is based on NiMH and the other is Lithium-ion. I've used the NiMH and I'm not at all happy with the welding/mechanical connection on the negative side of the battery. Both are Low Self Discharge (LSD) which is good. I'd go for it and get the LiON 9v @600mAh -- In theory it should last 3x longer. These NiMH 9v are "claimed to be LSD" but I get poor shelf life, nothing like the Sanyo 'White Label AA" which are fantastic NiHM LSD batteries. I've had superior results with Lithium-ion, but you pay the price. You will have to run your own tests and real world applications. I'd buy the set with the 4 batteries and the recharger (as they are only asking a bit over $2 for the charger -- some batteries can be touchy with what charger is charging them. Would enjoy seeing your feedback on your experience.

mAh = milliamps x hours. It is the capacity of the battery. The higher the number the longer the battery will last.

they aren't full 9 volts. all of the devices i use them in work fine on their voltage. i just checked 1 of my spares that has ben sitting since feb and after 6 months it has 8.23 volts on a volt meter and on a battery checker it's meter is is as high in green as it goes. For us these last longer than any others we used rechargeable or none that's why we had one that's ben sitting 6 months

You would have to check with B&D.; I looked on the battery and the box it came in and could not find anywhere what the mah rating is (which is kinda strange). I can report that they do last a long time.

The key is the 11000 mAh, they last longer between charges. I bought six and am planning to buy more.

Voltage is the same.. mAh rating is overstated. It doesn't last as long a genuine battery but for the price I suppose I will live with it. Probably 20% less run time. Also energy retention isn't as long.

I also use SONY NI-MH batteries and I haven't experienced any problems. I think what they meant to emphasize was to use NiMH type of rechargeable batteries. Here is what Olympus recommends: Ni-MH Quick Charger and Battery Set (B-90SU) http://www.olympusamerica.com/cpg_section/product.asp?product=1393&fl=5 "What is the difference between Nickel Cadmium (NiCad) and Nickel Metal Hydride (NIMH) batteries? Both NiCad and NiMH batteries are rechargeable. The main difference between the two is the fact that NIMH batteries offer higher energy densities than NiCads. In other words, pound for pound, NIMH delivers approximately 30% more capacity than its NiCad counterpart. " Reference: http://www.batterymart.com/c-battery-facts-faqs.html#lith-alk

They can both be used in all the 8 volt tools interchangeably but the the 9096 battery is larger and has a MUCH higher capacity, and will last about twice as long on each charge. The 9096 has 2.4 amp hours, and the 9098 only 1.2 amp hours. Both use NiCad chemisty which is less expensive than the smaller and generally better lithium ion technology, that is also popular today, but takes a different charging system. NiCad is not as powerful as NiMh per ounce, but has much better performance at cold temperatures, and also holds a charge longer.

HI, The original batteries only state they are 9.6V, no Ah stated. The replacements say they are 9.6V and 1.3Ah. I just checked on a replacement battery that has been in a tool for at least 6 months and it still very well charged. This pair of batteries is as good or better that the originals.

My original batteries did not have mAh (milliamps per hour) rating, but the higher number just means they will last a lot longer without being charged. My old batteries had to be on the charger every day (even when new). These batteries last me 3-5 days before they even start to go down. I bought these batteries for replacements in my Uniden model # DECT1580 phones and am extremely happy with their performance - much better than the originals. Hope this helps.

Not long, 2 or 3 months at the VERY longest. This is a trait of the NiMH batteries, NOT the brand. Personally, I would top-off any battery I was planing to use during an electricity free vacation, no earlier than a week beforehand, in order to have the most juice on hand when you need it. This is from my personal experience with a wide selection of brands and a wide variety of battery ages. Everready, on the other hand, claims that NiMH batteries in general will loose 50% of their charge in six months. I expect this may be the case under the very best laboratory, tempature and humidity controlled conditions. Not under normal conditions, like your camera case, electronics drawer, or your battery shoe box. Now... While I've never seen a STORED NiMH battery hold a charge that long, I HAVE found that using them in something that draws a small, but constant current, will give you a MUCH longer shelf-life than charging them and then storing them. Depending on what they are in, I've seen them last up to a year or longer.

AA are 1.5V and ~2600 mAh. 9V typically have ~500 mAh. This means 2 AA have ~7.8 joules of energy and a 9V has ~4.5. So 2AA should last longer if the power consumption is the same. Of course the quality of battery varies but for starters at least.

The difference is the mAh which means the amount of charge the battery will hold. The higer the mAh the longer the battery will emit power between charges. It will work.

before I ordered I had to look it up. I found that mAh is a measure of the amount of charge stored in a cell or battery (set of cells). One (1) Ah is the equivalent of 1000mAh, and so the statement can be made that a cell with 2000mAh of stored charge can supply a device drawing one (1) mA for 2000 hours -- before needing replacement or recharge. Bottom line is that the 1600 mAh has a supposedly longer life before needing to be recharged.

The spec sheet doesn't say that number outright. However, if you use a 5v useable voltage cutoff (which they do in the data sheet), the battery will go 310 Hours at 2ma (620mAh), and at 10ma it will go 60h (600mAh). So there ya go. However, if you're using a 9V, your circuit probably needs at least 7V to run, so keep that in mind while choosing capacity.
