Rated 5 out of 5 by Reagan from Musician rocks all night with Duracell Made the switch over a year ago and never looking back. Always load freshly recharged batteries in my in ears, wireless transmitter and acoustic guitars. Without a doubt these batteries and charger rock all night. I recharge my alternates during the gig so I'm good to go the next night.

Rated 5 out of 5 by Elwood Bluez from Mr I have been using this, along with the original batteries, for well over a year now. I find it hard to believe there's so many negative reviews. I swear by Duracell batteries and have been exclusively using them for 30 years!You can NOT beat their quality. Rated 5 out of 5 by Harv24jg from AA/AAA BatteryCharger (is)1000. After about 6 weeks use, batteries began blinking red when I know that they were good batteries. After reading "Don's" reply to clean the battery terminals, I had a small piece of 000 sandpaper and brushed + & - poles and now it works great. A small price to pay for a great charger. $25.00 @ Sams Warehouse. Rated 5 out of 5 by Brooks from Love it! Bought it today. Charged up the 4 AA's and off I went! I'm going to be using them in an Raspberry Pi + robotics combination and I think they'll work very well. 2.5 AH in a AA is a lot of power! Rated 4 out of 5 by avgenao from Blinking My charger has been working perfectly for about the last two months and now when I put the batteries on the charger it starts blinking. I haven't seen the charger produce a green light in over two weeks. Rated 4 out of 5 by DDddddan from Works great! We charge several batteries a week. No complaints. Rated 4 out of 5 by JohnMc from Decent battery charger Misplaced the manual, can't recall the difference between the blinking red and solid red led, been about 16 months since purchase and two the batteries gave up after estimated 30 charges. All things considered I'd b another if the price was $5-8 bucks cheaper in Canada. Rated 4 out of 5 by Eric from Okay
