  1. Reliable

    Posted by Pigger on 20th Mar 2013

    I purchased the batteries to run my hunting lights and I have not had one bit of trouble since I started using them. Can't beat the value compared to the non-rechargeable batteries prices.

  2. great!!

    I use it once or twice a week, and love it.

  4. A Great Value!

    [...] good value for the money.

  5. Saved $$

    Posted by BEARS RULE! on 20th Mar 2013

    Charges quickly. Saved $$ without having to continually to buy new batteries.

  6. Good product but......

    Posted by Reggie on 20th Mar 2013

    Good product but the batteries I received were 3.2volt, not 3.0 volt. May not be an issue for some but could cause issues with charger and if your product was close to max voltage with the 3.0volt, could cause issues as it's close to an extra half a volt (and maybe higher after fully charging)

  7. Works Great & Green

    Posted by malebel on 20th Mar 2013

    I use it in my Sekonic light meter.

  8. Reliable & Rechargable
