I have purchased Tenergy products for more than a decade and am still using most of the batteries purchased during this time (D,AA,AAA,C). My old battery charger gave out after all these years and I recently purchased a new battery charger. This charger proved defective. I have experienced hassle free Support in remedying the issue. I will continue to look to Tenergy for my supply of superior rechargeable batteries.

The batteries are fine, good quality. But the shipment took too long, 6 day before leaving their dock.

I was looking for a charger that could charge a single cell. Most chargers have to charge in pairs. My situation was of a set of 4 NiMH cells, operating in series, that used the radios internal charger was not equally charging all 4. One battery had dropped to .87 volts. Normally that would be considered a spent battery and be tossed. Charging as a single unit might bring the battery back to life. The TN486U started a charge cycle. If the battery was not capable of charging there is an indicator light for that. The battery is a high capacity 10,000 D cell. An active 4 segment charging indicator confirmed the cell was accepting the charge current. As the battery progressed the first, second, third and finally fourth indicator segments went solid. In 18 hours the battery was brought up to 1.4 volts. After 2 hours it settled to 1.38 volts which is close to what the other batteries had measured. Ordering was easy to find the unit I desired. Shipping was free. I put in my order late on a Saturday and it arrived Thursday afternoon. Being able to charge a single cell and mix AAA, AA, C, D and 9 volt NiMH and NiCD makes this the only charger you need to have. Great product.

Will order from Tenergy again. The provided shipping options were incorrect for shipping batteries so shipment was delayed. I got credited for the lower cost of ground shipping but had to pay brokerage fees.

It's almost impossible to buy these products in Canada. The shipping charge on batteries was very expensive, over 100$! There should be more options.

I like being able to purchase directly from the manufacturer instead of through corporations like Amazon. Tenergy's website was easy to find what I needed quickly, easily, and the prices were clearly marked. I am happy to purchase from Tenergy because they make a good and reliable product that my family needs.

My replacement battery pack for a Brava 380 was less than 40% the price of a pack on the irobot website. So far it charged up perfectly and works well.
