What is the difference between Ultimate and Advanced Lithium batteries?

Ultimate lithium batteries last longer than the advanced lithium batteries. I have used both kinds in games system (WII contollers) and the ultimate have lasted about 2 weeks longer than the advanced lithium batteries, and that is marathon usage (about 6 hours a day).

Per Energizer's webpage, Ultimate lasts longer than Advanced and both last longer than Max.

Stronger unit runs longer. If you do the research you will see for the same price you can get the 32V lithium Battery.

These batteries are lighter then the tenergy 10,000 mah high capacity model. Apparently the premium model is made from a different composition that has higher performance and better features.

My unit has AA batteries in it, so battery life depends on what quality of battery you buy. I got about a year and a bit because I put in Duracell Coppertop. Maybe the new Lithium will be better for longevity.

the xrp are the better batteries. i believe these are the best lithium 18v they make.

You can use rechargable batteries, but you get more power when you use lithium batteries.

According to the specification listing, it should accurately test this battery. It lists that it checks 1.5v lithium AA (L91) and my understanding is that the Lithium Ultimate is that battery type.

While alkaline batteries are less expensive I think lithium batteries are the way to go. They last much longer and withstand cold temperatures better. I shopped around because they are rather expensive and found that at least in my area walmart had the best price. I'm told that you would spend as much replacing alkaline batteries as the cost of the lithium ones.

The batteries that are included are the original lower capacity Ah. There are now higher capacity 12 volt max lithium which lasts significantly longer. I don't know exact Ah ratings. I use the higher capacity ones for the the tools and use the lower capacity ones for the LED work light.

Lithium only according to booklet. Like the lithium better than ni-cad. Smaller and lighter. They recharge in an hour. The smaller packs that comes with are all right. They last about one hour. Keep your charger handy and the second battery charged. If you are going to use it a lot buy the heavy duty lithium pack. They cost about 120.00 at home depot. Which is a licsened repair for Ridgid tools. Lithium runs at a consistent voltage and amps till the battery get to a point and shuts down. Where the ni- cad runs down continuly losing power through the charge.

I'm using AA Duracell Coppertop at present but I will switch to Energizer Ultimate lithium after my next trip to the market. They last much longer and are much more cost efficient for cameras. Hope this helps.

These AA Duracell Procell's are Alkaline batteries. They are advertised as lasting longer that the regular alkaline Duracell Coppertop; but, by how much, I don't know. Lithium AA's will typically last over twice as long as alkaline AA's in the same electronics.

Lithium will last longer, but at a much higher operating cost. You could always carry a spare set of batteries with you in a protective case.

I have both, the extreme and the Ultra. Both work great, can't tell the difference.

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.

Not much difference in weight. Unless you want to get the lithium-ion. Which is a lighter battery.

They ARE lithium. They are the latest technology in terms of the 18 volt system. And they work very well. Great power and they have great run time.
