Great value and does the job.
I bought this less expensive charger as a second unit for my motorcycles and found it to work as well as the more expensive Optimate 4 Dual program charger.

Easy to use
Just hook it up and it does the rest. I have an 05 convertible that I don’t drive in the winter. Battery was run down and car would not start. After charging the battery for a few hours it started and now is just keeping battery trickle charged.

The Optimate 2 is an excellent trickle charger-maintainer. It works great especially with the new style portable generator battery that are stored in an unheated location. By connecting the maintainer to the battery it keeps it charged and warm so the electric start will work in extremem cold weather.

Don't need to take out battery. Very convenience.

Best maintainer you can get. Cheap and easy, but provides the best possible off season charting and maintaining. I have 5+ optimate chargers for different things. 3 of them are these. One stays on my tractor all winter so it's ready for snow removal and two on my SXSs
