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

Good replacement for a MX Master. Easy to replace. Holds charge well

Replacement battery for my harmony touch remote. Was easy to replace following some online videos I found. It's only been a few days so far, but initial impression is good and lasts similar times back when it was new.

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!

I’m writing this review after a week with the battery installed. The installation was simple, took about 10 minutes. YouTube videos if you need instructions. Take your time. Before replacing the battery, the remote would last less than a day. Not surprising as it is about five years old. The new battery has given the remote a new lease of life. Now I can get a few days out of the remote before I have to put it on the cradle. Highly recommended

Good quality

Dead after about the 10th cycle. What a shame, the first few cycles held power far longer than my old (original battery). Shame that this has now failed.

Unfortunately the connector was too small so was not fit for purpose.

just what you need

Ok

Passt

Hat in meinen 7-jahre alten Trackball super gepasst. Aufgeladen und nun läuft das Teil wieder super. Lieferung von Amazon innerhalb 24 h, perfekt.

皆さんの書き込み参考に､届いてものの10分程で交換完了しました(ホイール交換や掃除で何度か外しているから)､G703の元の電池は30mmX12mm程度で1/4～1/5程度で容量も240mAhとサイズも小さくプラスチックの壁を取り除く加工が必要と成ります､カッターで壁の下にキズを付けラジオペンチで千切りましたが､簡単にキレイに加工できました｡又取り付ける前の元からの電池充電は85％を示していました､交換後の電池の充電状況も､たまたまなのか？85％でした､50％で交換したら交換後も50％と成るのかも知れませんが？そこは判りません､別の方､検証してみて下さい､充電が正常に完了したら､良いのですが､異常があったら追記します｡

Logitech MX Masterのバッテリー交換に使いました。 問題なく充電し使用できています。
