Thanks for the link! I ordered the maintainer.Definitely, use you current charger to get the battery voltage up if needed, but don't leave it connected long term.
Moving forward, I would strongly recommend buying a battery maintainer instead of using a standard trickle/charger.
A standard charger continuously charges, regardless of battery level, which can "cook" the battery.
I would suggest a charger which is intended for maintaining a battery in long term storage and are usually used for motorcycles, classic cars, etc.
I have the same problem as you, one of our vehicles currently isn't being used much.
I have this charger:
I think it comes with one set of ring terminals, but it wouldn't be a bad idea to purchase one for each vehicle, then simply plug the charger in instead of messing with alligator clamps.
additional ring terminals
Shumacher seems to make a good one as well:
Yes, I'm thinking about making and hooking up a memory saver to try to avoid memory loss but wanted to check here first whether it would be worthwhile.I haven't used the pigtail. With a bit of care, could you temporarily jumper the negative cable to the chassis in order to fool it into thinking that nothing has happened or changed?
Hi CroMath,If you don't actually remove the terminals from the battery posts you won't lose your continuous connection. The nuts aren't necessary to keep the current flowing - you can take them off and put them back on without any issues.
I posted a picture of my pigtail connection in another thread. The negative is straightforward, the positive connects as shown in the picture.Hodna, Hotdog16 or anyone who has installed a pigtail cable for a battery charger/maintainer:
When you removed the nuts on the battery connectors to install your pigtail, did the battery disconnect from the van resulting in loss of computer and radio memory?
Yes, I saw that picture of your pigtail connection to your battery terminal. Thanks for posting it.I posted a picture of my pigtail connection in another thread. The negative is straightforward, the positive connects as shown in the picture.
The vehicle does not lose power when the connections are made. However, there is no need to worry about losing radio etc because all of these are stored in memory and are retained.
Thank you very much for sharing that info. It will add to the knowledge bank when members of this forum need to have their van's battery replaced. I will contribute info on our van's FLA battery (12 months old now) as appropriate.Since charging on 5/3 the van has sat. I got a low battery warning yesterday (5/15), so ended up charging it back up to 12.6V again. So it took 12 days to go from full to low for an AGM battery that's 3 years old.
