According to the product description of Lenmar Ready-2-Go R2GAA8 Rechargeable NiMH AA Battery, the Lenmar R2G cell is even better than the well-known SANYO eneloop, because:

- It is "Ready to use right out of the package" just like eneloop, and
- It has a higher capacity of "2150mAh", instead of just 2000mAh for eneloop.

I purchased a set of those Lenmar R2G cells a few months ago, and analyzed them using my old La Crosse BC-900. Here are my findings:

- When received, the average remaining charge in Lenmar R2G cells is only 800mAh, which is less than 40% of rated capacity. So the claim of 'Ready To Go" is marginal at best. In contrast, all eneloop cells I have tested came with at least 70% of rated capacity - even those manufactured 22 months ago!

- After several Discharge/Recharge cycles, the average capacity of Lenmar cells reached 2030mAh, which is below the rated 2150mAh. In contrast, most of my eneloop AA cells measured ABOVE rated capacity, close to 2100mAh instead.

- The self-discharge rate is slightly worse than that of Sanyo eneloop. After sitting on the shelf for 100 days, average remaining charge in Lenmar cells is 85% of original capacity. After 170 days, it is at 79%. In contrast, all name-brand LSD cells I have tested (such as Sanyo eneloop and

After using these I do not think I will ever buy regular rechargeable (the non-low self discharge type) batteries again. These have a significantly longer shelf life and stay almost fully charged months after they are charged - just like the advertizing states.

I have been using rechargeable batteries for 5 years now and I have seen the vast improvement in both capacity and the ability to hold a charge for length of time.

The R2G's have held up to what they have promised as other batteries of a higher capacity of 2800 mAH might have kept my demanding bluetooth keyboard with lots of obstacles in the the direct line of sight, so more battery power needed, charged for maybe 3 to 4 days without ever being turned off.

The R2G batteries I can leave in for 7 + days where the longest is 9 days.

I use two BC-700 battery chargers which you can get right here on Amazon as I only use rechargeable batteries and a lesson learned is 200, the default charging rate is the one that will give you the longest life and the most use out of your rechargeable batteries.

I received four of these AA batteries when I purchased the awesome Lenmar R2G802U R2G charger from Amazon:
Lenmar R2G802U R2G 2 Hour Charger Includes USB Output and Alarm Clock with 4 R2G 2150mAh NI-MH for AA/AAA Batteries

I was looking for a new home charger and wanted to try the world of low discharge / pre-charged NiMH batteries. Let's just say that I chose well. The charger is awesome, charging each cell independently, with lots of features, including the ability to charge USB devices (like my bluetooth headset) when plugged into the wall.

And for the batteries? Like another poster said, I am never going to by normal NiMH batteries again. One of my biggest disappointments with NiMH batteries, was that they would just die on their own after not using them for a while. Now, with these R2G cells, my digital camera can last for weeks and when I need it, it still turns on and takes pictures. I broke my own rule and bought some normal NiMH AAA batteries for my flashlights (since they were only six dollars for four batteries at wallyworld) , but I think I might try some of these AAA R2G batteries next:
Lenmar Ready-2-Go R2GAAA8 1.2V 850mAh Rechargeable NiMH AAA Battery (8-Pack)

I would definitely by more Lenmar R2G batteries, and like I said above, I highly recommend their R2G802U charger!

These Lenmar's work as advertised. I used them straight from the package and they worked nicely. Also they seem to last longer than other Rechargeable batteries. The Ready-2-Gos are similar to the Sanyo Enloops in terms of ability to use out of the pack and to hold a charge much longer than other rechargeables. I was very happy with the Enloops but decided to try the Ready-2-Gos which are approximately 20% less expensive. In terms of performance I haven't noticed any difference between the more expensive Samsungs and the Lenmars. Finally I would have been leery of trying some no-name brand battery. However I've had very good experience with Lenmar's replacement batteries for my Cannon cameras over the years. If you're looking for reliable rechargeable batteries that work straight from the pack you'll likely be very happy with the Lenmar Ready-2-Go batteries.
