DC 3.7V 1150mAh Lithium polymer rechargeable battery for Logitech Wireless mouse G403 G703 G900 G903 Prodigy RGB 533-000130，DIY 3.7-5V Electronic Products with Built-in 3-Wire Battery Replacement

Ok

Buona qualita'

This battery is substantially larger than the one that is in the G703, but after some cutting and sanding on the mouse, it can fit. The cavity that the battery goes in is sized appropriately for this battery, leading me to believe this was the original design or something. In any case, it takes about 20 minutes to remove the brackets to hold the smaller battery, and then it seems to work.

La livraison correspond bien au descriptif. J'ai quand même récupéré la fiche/prise sur l'ancienne batterie, ne trouvant pas le modèle exacte. A voir avec le temps

After looking around for different G903 replacement batteries I took a gamble on getting this, glad I did, it fits perfectly in the battery bay, the power cable connector is exactly the same as the original, fits into the board socket no issue, it has a paper tab on the back to peel off for the sticky so it stays still when placed in the bay, I added 2 bits of double sided sticky in the bay anyways & stuck it to that, screwed the case back together, switched on the mouse, mouse working again, so for £17.50 it has saved/revived a dead £100+ mouse, happy days, also, as the milliamps are higher than the original 750ma it’ll last longer between recharges, so if you’re looking to replace the battery in your Logitech G903 Lightspeed this one is good for it! Easy to replace, just peel off the foot pads & undo 6 small screws(magnetic), definitely recommend this battery replacement!
