00:00:00 01-28-2012 Best charger I've used yet Overall:  
  • Other Thoughts: Refresh feature is great, also that it keeps a trickle charge going when full to top batteries off. I've charged several dozen batteries so far and it quietly does its thing as expected. Satisfied so far but will update if anything changes

00:00:00 01-25-2012 Great battery charger! Overall:  
  • Pros: seems ok
  • Other Thoughts: This battery charger is a bit more expensive but really worth it. I like how it reports on battery condition and tells when the battery is fully charged. I've used it to weed out "tired" rechargeable batteries from the ones that are still good. All in all a good deal.

Product FAQs
  • What is the difference between a battery charger and battery maintainer?
  • A battery charger just charges the battery, a maintainer helps keep the charge in the battery while its not being used or is in storage, they do work good, but you have to have a good battery to start with. Other wise, it won't actually charge a battery up, all it will do is help maintain what voltage the battery already has in it, good luck.

  • How can I tell if my battery charger is working properly?
  • If you have a voltmeter, check voltage before turning on the charger. Then re-check with charger on. You will get 3-5 volts difference, depending on the charger and battery. If it is a small charger, after turning it on, remove a charger clamp and scratch it across the battery post. You will see the sparks. Don't do this after the charger has been on for a while,  as there is the danger of blowing up the battery because of the explosive gases coming of as a result of charging.

  • Will this charger work on my battery even tho its not the same voltage?
  • So long as the output of charger is equal to or higher than the battery's, then it'll be fine.
