This charger is a technical tour de force. It can diagnose many common battery problems, plus run alternator tests. But what we really like is the 10 Amp maximum charge current, which rapidly revives even a fully flat battery. Decent leads and clamps are a bonus, while the gentle pulse mode conditioning cycle is very effective.
