FIXED: Replacement batteries for Logitech MX900 (or 700)

[PennyArcade]

I think my batteries for my MX900 are dying. The funny thing is that I replaced them with some Sanyo 2300 mAh and the mouse starts blinking red. So I place it in the charger and it stays blinking red (should be blinking green).

I am wondering if any of you that have MX900 or MX700 have replaced your batteries, and if so, what brand and type you replaced them with.

Thanks!

Are the batteries brand new ?

If they are, it could just be the batteries are too discharged. Try to fully charge them up in a charger. Use them to drain them all down. Repeat the process one or two times. Then, put them in the mouse ...

I've been using the batteries that came with my mx700 for probably close to two years now, they still hold a decent charge. For your sake, I gave my energizer 2500mAh a try in it and they worked just fine...but they're fully charged and have been used before.

I replaced the ones in my 700 with generic 2100mah NMH AA's. Works fine.

Get a 4 pack of energizer 2500mah rechargables...Its got at least 2x the life of the ones that come with the mouse... and you can use the extra 2 batteries for gaming emergencies. lol

You can probably shop around and get an external charger with the 4 pack as well for $24. I rarely use the mouse charger, simply because the newer chargers charge faster.

thanks for the replies... I'll try fully charging the batteries first.

Update

I recharged some 2100 mAh batteries with a separate charger and plugged them in.

It works now. I guess you cannot charge completely dead batteries in the mx900 charger.

Thanks for all your help
