Battery Equalizing / Hydro Caps

I am overly dilligent in maintaining the battery bank on the horn. Running out of power on a trip is a drag at best.
Last night, after it cooled down, I put the charger to the equalizing setting to stir up the 'ol electrolytes, it has been six months or so and it was time.
My wife went out to the rig, unbeknownst to me, and when she came back in she commented how bright the lights were! We dodged a bullet as no bulbs blew or plastic lenses melted, as some times happens with 15+ volts going into the system.
HYDRO CAPS
I just found this item and was quite excited until I saw how much they were. They claim to reduce water loss by 50-80%. Has anyone used them? I wonder if they would give the batteries a longer life or if the number of charge cycles would be the same?

Hey Rog, That's the ONLY reason I haven't bought any for my 4 6VDC batterys. I have researched them a couple of times but the $$$ always kept me away. If you get em, let us all know how they work. Thanks

Gary, I figure I can buy a whole "boatload" of distilled water for $50 a battery. I am going to my battery guy this afternoon to try to make a deal. My threshold for pain on this deal is about $10ea. That is the cost of two more T-105's. If you screw up and don't check 'em often enough the top of the cells get dry and you lose the battery. If the caps last a few years the $ might be worth it...........

Here is an option............

I put them on my trojans and I still have to add water a couple of times a year.

timk,glad to hear from you. Did you get the hydrocaps or the misers? If you only have to water them a couple of times a year that is a big improvement. Here, in the warm and dry climate, the T-105's get really thirsty and I have to check them at least every 60 days and always have to add water...............
