Gerald,
I've been using $5.99 Battery Maintainers from Harbor Freight successfully for several years. I use two on the GMC and one on my little '88 Fiero GT that I take to car shows. They have always done a perfect job of maintaining the batteries and do not boil the water out.
These little devices maintain whatever the voltage was when you hooked them up. For example, if the votgage was 12.5 when you hooked up, it will maintain that voltage for however long it is hooked up, no more or no less.

My wife recently bought a new BMW X-1 which, like many new cars, needs a battery tender if it is to sit for an extended period of time. There are so many sensors and do dads that wake up and sniff around periodically that the battery may run down too far for the keyless entry stuff to work if it is not driven once in a while. For our Alaska jaunt this summer we will be gone for two to three months so I looked for an appropriate battery tender for the AGM battery in that car. I found two manufacturers who seem to be a ways ahead of the others when it comes to the sophistication of their charge and maintenance cycles - CTEK and NOCO with their Genius line. I selected the "NOCO Genius G7200 12V/24V 7.2A UltraSafe Smart Battery Charger? because it also had the ability to be used as a 12vdc power supply. The CTEK unit could not although that is the one BMW itself sells as a rebranded offering. They both have models running from around $30 to $200. The one I purchased was $80 from Amazon with prime shipping.
It seems to work as advertised. When I first hooked it up it analyzed the state of the charge of the AGM battery and brought it right up to 100% step by step. It is an eight stage charger with settings to handle flooded cell, gel cell, AGM and the newer AGM+ batteries, is CANBUS compliant and can remain connected 24/7 for long periods of time without harm to the battery or the on board electronics. It would be a good, quick and safe charger/tender for our GMC owners who do not have smart chargers on board, or who have a mixture of battery types. All the normal disclosures, no affiliation with the company, not compensated, etc.
