900Mah Lithium Battery For RAZER Mamba Gaming Wireless Mouse Part: FT703437PP, RZ03-00120100-0000 , Model : RC03-001201

After contemplating purchasing this 3.7 volt Lithium Battery as a spare for my Razor Naga Epic Gaming Mouse, I decided to take the plunge and risk the purchase. It only cost me 13 dollars and since I am an Amazon Prime Member, I received second day UPS shipping at no charge. That's a lot cheaper than if I would have bought the battery directly from Razor and paid their shipping charges amounting to a total cost (mouse and shipping) of around 33 dollars. Well, I ordered the battery on Amazon.com on Friday. I received it on Monday morning. Certainly, no complaints there. I installed the new battery in my mouse right away, and started using it immediately in wired mode so it could charge itself. It quickly charged to full power, less than an hour. I then switched to wireless mode where the battery performed just as well. I play MMO games which require high end graphics, and let me tell you this battery held it's own just as good if not better than the original 3.7 volt lithium battery that came with my Naga Epic Mouse. Why have two batteries? I like playing in wireless mode. So, when one battery charge drains out, I can just pop in the other (spare) fully charged battery and I'm good to go for many hours more. Again, this Lithium Battery sold by Power-O-Matic is a good alternative and works just as well as the original battery sold by Razor. I highly recommend it.

I had a Razer Mamba mouse for just shy of 3 years when I started having a problem; the darn thing wouldn't charge! Razer's customer support was absolutely amazing and sent me a brand spankin' new battery, completely free of charge, just days later which fixed the problem. However, I figured I was super lucky to get that kind of service and if this kind of thing were to happen again I'd be pretty screwed. So, I bought one of these third-party ones as a backup. I ended up swapping out and keeping the official one from Razer as a backup, and using this battery.It's been about a month now and I haven't had a single glitch, issue, or problem with the battery life. It performs exactly like it's Razer counterpart, and the price is right.Need a battery replacement? Go for this, but only after seeing if Razer can hook you up; I've always been a fan of their products, but they truly won me over when they shipped me a new battery for a 3 year old product entirely at cost.Razer can look forward to future business from this guy!

I don't think the battery lasts as long and it is a lower powered battery. But it is cheap and does what is says. I play a lot of games, sometimes for over 8 hours. Batter holds up pretty good. WAY cheaper then the one Razor sells, with their rip-off 20 buck shipping fee.

Didnt work at first only a few lights kicked on and then mouse died. YOU NEED TO PUT A SMALL LAYER OF TAPE IN WITH THE BATTERY. The fitment is slightly off and the leads don't make constant contact. You only need a piece folded over a few times no problems so far and the battery is reading full.

I purchased this replacement after the original battery almost burst (the original expanded to almost double in width, bursting the battery cover off the mouse and knocking itself off its charging stand). This replacement fit perfectly and now I get double or triple the life that I was getting with my old battery.

Battery life is great, but I don't think it has a consistent power output. When using it my mouse cursor doesn't move smoothly and instead will stutter, jump around, and freeze a lot as though my mouse is randomly disconnecting/reconnecting super fast. I originally got this as an extra battery for my gaming mouse, but it makes any games requiring aim/precision and quick reflexes unplayable. For example, if you're playing a first-person game you'll be walking forward, look slightly to the left and then suddenly you're looking directly up in the air. Out of the box it worked great, but after the first charge this problem now persists. If I switch back to my original battery the problems instantly disappear.Don't buy this battery, it's a huge waste of a tenner.

Good price and worked perfectly on my Razer Naga Epic mouse. The shipping took awhile (10 days or so) but it was within the timeframe they quoted, so I can't complain. Razer wouldn't replace my stock battery even though it lasted less than 6 months and wouldn't hold a charge any longer. This was a a good replacement for the price.

Pulled my Mamba out of electronic purgatory for a new computer build and found the battery cover was off and the battery was sitting funny in the mouse. Upon deeper inspection the battery was puffed up and had infact popped the cover off. No local stores carried the replacent and a specialized battery store said they could get one in a week at about 30 bucks. As a prime member I got this one in a couple of days much cheaper. Fits like a champ and an extra 100 milliamps to boot. Very happy with it as it lasts quite a while before needing charging.

works like a charm!so far there's no problem.fits in the 2012 mamba perfectly.a full charge could last several hours (which is a easy full day use).

Der Akku, den ich erhalten habe, sieht 0,00 aus wie auf dem Produktbild.Es handelt sich um einen ausgesprochen minderwertigen Nachbau, der zu groß für das Akku Fach meiner Razer MAmba ist.beim Einbau sind noch die Kontakte des Akkus einseitig abgerissen (!!!) weil es sich nur um eine dünne Platine handelt, die auf das Akku geklebt wurde. Meine Maus lässt sich nicht mehr schließen, und beim versuch ist der Akku Fach Deckel gebrochen.Vielen Dank dafür.

Surprisingly works well and no problems. Hasn't blown up. It's a battery, not much to review.

Rispetto all'originale razer risulta di qualità inferiore e l'autonomia del mouse sembra molto ridotta.Molto meglio acquistare la batteria originale anche se a prezzo decisamente superiore

Good cheap battery, was worried when purchasing that it would not be compatible. But it works properly and long life.
