Battery vent caps

[gdavet]

I am having trouble with corrosion on the battery tray. I read in a recent issuse of a motor home magizine that there is a new vent cap to prevent this venting that seems to cause the corrision. Any one remember the name of the caps and where you can get them?

I have found that regardless of whatever cap you have that with the standard battery you will be presented with corrision, etc. It really is not difficult to control. Wash your batteries with lots of baking soda and they will come up very clean. Purchase a spray from an automotive store to prevent this corrision and your situation should be corrected. A little maintencance goes a long way?

I have used hydrocaps for years on my last 2 coaches. I got them to cut down on water usage and venting of explosive gases. I found that the other advantage of their use was next to no corrosion. I plan on using them on my new coach as soon as I get home. There does have to be clearance to install them, the cables get in the way sometimes. They are a bit expensive and hard to get fight now. Here is link to the site I get mine from. http://store.solar-electric.com/hydrocaps.html

For anyone considering Hydrocaps, they sound like a good solution to outgassing, if you have relatively new batteries.

However, if you are going to buy new batteries soon, I highly recommend that you consider Lifeline AGM batteries. AGM batteries are sealed (no watering required), do not outgas at all, and cause not corrosion at all. The only drawback is the additional cost. However, for the cost of the Hydrocaps, apparently $60 per battery, that would cover about half the additional cost of a Lifeline AGM battery. In addition to no outgassing, the Lifeline AGM batteries have other benefits:
1. Faster recharge
2. Lowest discharge rates when unattended
3. Shock and vibration resistant
4. No battery watering required

I have the Lifeline AGM batteries in my coach, and I swear by them. Check 'em out at this link: Lifeline AGM batteries
