I recently had to replace the battery on my MX-5 after it somewhat suddenly gave up on me. In fairness it was over eight years old, the last two of which have been with only light and occasional usage. As a result I have started looking at battery chargers in an attempt to better forestall any future occurrences, particularly in the present circumstances.

The helpful and seemingly knowledgeable young mechanic who replaced the battery recommended looking at the CTEKs, which I have now done - in particular the MXS 5.0. It certainly appears to be a reasonable option for the relatively undemanding needs I have. Before I take the plunge though I would be interested to hear of any good/bad experience with CTEKs and/or any suggested alternatives.
