I looked at them.

From experience I know that the AGM or spiral batteries are 'very'
picky about being overcharged. They will still vent hydrogen like a
normal battery on hard charge, but just don't have that much to vent so
they 'boil' dry easy.

For this reason I personally would go for one with an AGM 'switch'. I
think it would be worth it.

The second one also has the AGM sensing technology and it's waterproof.
Sometimes the fancy stuff like the 1st isn't always the 'best' stuff.

The 3rd or 'cliplite' only says it is for conventional lead acid
batteries....

If you will be charging at home or from a power grid, input voltage
sensing isn't needed like some have for running off inverters or generators.
