Ctek 3300 Review - Hands down the best battery tender / trickle charger made

Here's a raving Ctek 3300 review from Amazon.com:

By Richard J. Misner

I own two of these excellent chargers - they are very simple to operate and very durable.

The chargers are weatherproof, and you can permanently mount them in the engine compartment with the provided ring terminals, or just use the alligator clips.

The charger has a battery status indicator (low / full), and settings for Motorcycle, Car, or Gel battery. The charger cycles from trickle current, to pulses, and shuts off when the battery is full. There is no better charger for winter storage battery tending, bringing nearly dead batteries back to life, or just recharging boat batteries slowly overnight.

Finally, I should mention that the current version of the 3300 has some improvements over the already excellent older version (I now have one of each). The latest version includes:
- Heavier gauge wiring
- Much heavier and more durable alligator clips
- A nice zip-up storage case
