2 Pack - Replacement for Logitech MX Revolution (New Generation) Battery - Compatible with Logitech L-LL11 Mouse Battery (600mAh 3.7V Lithium-Ion)

After years I finally had to replace the stock batteries. These fit and function perfectly. They hold a charge for an entire 12 hours or longer. I found them as good as the original batteries were when I first got them. I highly recommend these batteries.

Came in a padded envelope. Arrived in good shape. Put them into service right away and they last a lot longer than the original equipment batteries, and gave no trouble.

I just use it for normal use browsing and so forth...the problem is my old original battery that came with the mouse still has longer battery life than these do !! My old battery would only charge up to 95% so I thought I would get a new battery for it since it was still a very good working mouse, but the problem is even my old battery still shows that it has 14 days of charge left in it, where the new battery only shows 2 days at a 100% charge and heavy use on the computer of 6 to 8 hrs of use per day without returning it to the charger each time will quickly deplete the battery...so bottom line the new batteries are not near as good as a 10 plus year old battery...and I might add it took two wks to get these little batteries that both could fit in my watch pocket...ridiculous !! They need to change the ratings on these batteries, because they are not up to par with the original battery....not even close !!

I bought this for one battery - sure wish I could buy just one, the other is in a drawer and will probably never get used. Other than that the price was still acceptable and it was relatively easy to take apart my revolution mouse and replace the old battery.

Poor battery life. I get slightly less run time with this brand new battery than I was getting with the original battery which I have been using since this version of the mouse was released. Very unhappy with the performance of these batteries and would not suggest that anyone else make the mistake of purchasing this product.

The L-LL11 battery from Certified Battery fits the Logitech G7 mouse and charger perfectly. Looking at bottom side of my mouse and charger...Logitech G7 mouse, M/N: M-RBH113charger, M/N: L-LH9Either Amazon has problems keeping reviews 'tied' to the correct product or reviewers are mistakenly leaving reviews for the wrong product. Based on other reviews for the L-LL11 battery replacement, I had prepared myself for shipping these batteries back and/or disputing the charge if they didn't fit my G7 or charger. Some reviewers were taping bits of paper to the batteries so they would fit/stay inside the charger or mouse??? This was not the case for me.

Fit great, holds charge, fast shipping and good packaging. Would buy again.Logitech G7 wireless rechargeable mouse batteries.

These batteries work just as reliably as the ones that shipped with my Logitech G7 10 years ago. And being new, they last a lot longer. Highly recommend.
