I bought this after owning a cheaper charger that cooks batterys and a slightly better one with less functionality that this. I did a lot of research before buying this and ended up looking at "Battery Mooch's" charger reviews. Mooch is a technical guy who mostly investigates rechargeable batterys but also did chargers and this scored as one of the best out of about 30 chargers he reviewed and rated. Im very happy i got it. it has a record/test funtion that charge/discharge/charges the battery recording the discharge capacity in mah and the final charge capacity in mah so you know what your battery is really achieving. It also has plug in test probes that read the internal resistance of the battery and voltage. And if that wasn't enough it also has a Current/refresh function which can breathe new life into old batteries. I have noticed that on a simple charge at 1amp the batterys are noticeably cooler than my other half decent charger which can only be good for the longevity of the batterys. No hesitation in recommending this its an excellent charger with some really helpful other functionsRead full review

Exceptionally well pleased with the Xtar Dragon VP4. Arrived promptly and tests and charges all the batteries I've thrown at it. Even revitalised 4 batteries from the dead battery box. Well worth the money.
