2 Pack - Replacement for Logitech G7 Battery - Compatible with Logitech L-LL11 Mouse Battery (600mAh 3.7V Lithium-Ion)

Once i found the screws and removed them battery replacement was easy. just like brand new now

As other reviews suggest, one must add a bumper to the back of the mouse(I bought this for a G7) in order to ensure power flow.I've had to fix this problem before, and tried using electrical tape. Don't do this, it is too wide, and will stick in the mouse and charger.I only had scotch tape on hand, but it ended up working well. I folded a 2 inch length of tape(sticky side out) to about the height of the back end of the battery, stuck it on, and then secured it with one more length of tape.

Good battery replacement for the G7 but the sizing is slightly off as its slightly smaller than the standard stock battery. Because of the smaller size, the metal contacts sometimes do not touch resulting in no charge. I had to manually rig some paper and tape to end of the battery to make it flush with the charging station (as well as the mouse). Aside from the size discrepancy, the battery works great and holds a long charge. Would consider purchasing again once these need replacing.

The Vendor shipped on time, well packed and everything was almost perfect. The battery, through no fault of the vendor was just a tad short and wouldn't latch in when inserted. In that situation it would not operate or charge. I added a small strip of cardboard at the bottom and it works fine in both the charger and the mouse. I think it is a good buy and a good product.

One worked the other didn't. Contacted seller and thought they were going to replace the bad one. Provided info requested and then never heard from them again even after repeated emails. Oh well, cheap enough. I was able to eventually resurrect the bad one but don't know if it will last. One works fine for sure.

I really wish the people who are saying that these are not working in their Logitech G7 would just shut the hell up! They are absolutely no problem in a G7. The idiot reviewers have some problem, but I think it's a mental one. There's no problem with these in a Logitech G7. So shut the F up already! You had me going crazy trying to cancel my order and harass this pore merchant for absolutely no reason. Wow, it takes all kinds doesn't it?!

Works as advertised in an old MX Revolution mouse that I need a new battery for.

These new fresh batteries do certainly last longer than the worn out batteries, but only last around 87% of the original factory batteries.(14 days versus 16 days.) However, these mice get used heavily each day so my results may not be typical of the regular user.

I love mu Logitech G7 mouse, but batteries have not been available for some timeThese batteries appear to have the same capacity as the originals Delivery in the Vancouver area very fast Appear to be from a local vendor

so far so good fit like factory ones

Worked great right out of the box

Item was as described
