  • Good as fat as I know I have used it yet
Size: 503870 (1500mAh)
Seems fine

  • Exact replacement part
I ordered this battery based on the dimensions and battery info on the old battery. The only difference was the new battery had a terminal connection for plugging into the desired device where the one being replaced was soldered in. I cut off the new battery terminal connection and soldered the two wires to the wires of the device and it works perfectly. Wife is very happy that her portable make-up mirror is back in business! Would definitely recommend this seller. Got in in 24 hours. ... show more

  • Great power for a 2x5w Ammobox sound system.
I set up an Ammobox w/ this battery to power a 2x5w amp w/ 2x2 1/2" speakers. 3-4 hours of use so far, and still 4 stars power, recharges w/ a usb 5v connection at the amp.
