Good products, excellent service!

When selection was out of stock, they quickly recommended an excellent replacement and sent them out. The batteries work fine, but they lack +/- markings (and are buttonless-type), so one needs to be careful installing them. The charger works great and is inexpensive.

It does exactly as advertised well made and does the job well.

Works Great

Works great. Batteries are charged quickly. Does exactly what it's supposed to do. No disappointments.
  • Fast Charge. Great low cost at sale price. Good quality product. Very durable power cord. A+ out of the box.
  • No 'Beep' sound to alert when charge is complete. If I had to guess, the spring loaded mechanism or the power plug connector on the TN270 unit itself would be the 1st things to 'wear out' from long term use.

from North Seattle asked:
August 6, 2015
Please forgive me for this "dumb" question - but does the battery charging light turn to blue when complete or from red - green. Want to make sure it is fully charged. I am using the Tenergy Lithium batteries that came with the charger of course. Thanks, Gordon
1 Answer
Thank you for your inquiry. The light will remain red when charging batteries. Once the batteries have completed their charge the light will change from red to green.
