  • Bug zapper renewed
Size: 603048 900mAh
Had a racket style zapper die from overuse. No longer charging. These work great, direct plug in, and are twice the capacity. How could you go wrong. Bugs beware!

  • a HIGH QUALITY LITHIUM ION BATTERY
Size: 603048 900mAh
The voltage is within specification, the battery holds a charge that meets specification, the battery discharges and recharges properly. The product is absolutely, perfectly satisfactory. I doubt that I will ever come close to discharging and recharging anywhere close to the number of specified cycles. ... show more

  • Polarity matches the 2nd picture NOT the 1st picture
The battery (1st pic) is in the opposite polarity of the first advertised picture (2nd pic). The second advertised picture doesn't even match the first advertised picture. Please update the pictures. Update: changed to 4 stars because connector is easy to change with a very small flathead bit on an electronics screwdriver. ... show more

I have a k3 keyboard with a dead battery I replaced the existing with this. I had to modify and sand a little of the keyboard but it has been working great and holds a charge well. No issue or complaints.

  • DANGEROUS - wrong polarity wired into connector
Size: 924260 2300mAh
My batterys' connectors had the wrong polarity because the red and black wires were attached in the opposite way by the product's supplier to the male JST connector. A result of their error was that my equipment over heated and no longer works.
