Dwight,

The deep cell batteries I had were in my car trailer that I used to have. The Optima that I now use in the trunk is a solid core type and won't spill if you split it. And even on them, it says you should use the 2 amp charge. However they told me that I could use the 10 or 50 Amp if I needed to, it is just better to use the lower rate, but I believe that applies to most batteries. I have a couple of small, $29.95 battery tenders that I hook to mine during periods of un-use and they have worked great. Every so often they will kick on for a few seconds just to move charge through the battery. But they won't charge a battery that is down. And as I stated above, I have had the same battery since 1997.
