I bought and use the "Battery Tender Jr.." It charges as it senses the battery's need, and "monitors" the battery when it doesn't "need" any charging.Its a good idea to keep it on a battery tender if your arent going to be running bike for a couple of weeks.
If you're winter storing your bikes in an unheated garage, and especially if you live in a COLD winter climate, I recommend you remove the battery from the bike and bring it indoors where it's warm(er). That is, after you've done all your storage prep on the bike.Now a question along the same line. I have two bikes that I will be storing during the colder weather. Can I buy one tender and keep switching it between bikes, or am I better off with two, or do they make one that you can plug multiple bikes (batteries) into? First storage for me this year....
I believe what he was trying to sell you at CycleGear was a tender. They have been pushing them pretty hard, on sale for like 15 bucks. I bought one. Even though l plan to ride through the Winter, a cold snap can last for two or three weeks here, so l figured l would be wise to get one.Do i need to always charge my battery with a charger? I was looking around at a cycle gear and one guy told me that plug in chargers were on sale and its a good idea to charge my battery often. Is this true?
Unless things have changed, and they very well could have, a charger a trickle charger used to be a 2 amp charger without the ability to know if the battery is fully charged and so could and would cook a battery unless it was disconnected. A maintainer is the only safe device to leave unatttened on your battery. Wade, you are the self proclaimed electrical guru, is that still the case or are the two still separate devices? I still have my trickle charger and no way would I leave it connected for any length of time. But it is some 30 years old. Things do change. I would certainly stick with a device that claimed it "maintained" your battery though. Not "trickle charged".wadenelson said:Keeping your battery on a "maintainer" or "trickle charger" is a great idea if you don't ride at least 2x a week.
From a battery mfr's website: At a 40% state of charge, electrolyte will freeze if the temperature drops to approximately -16 degrees F. When a battery is fully charged the electrolyte will not freeze until the temperature drops to approximately -92 degrees F.Even a fully charged battery can freeze/rupture if it gets cold enough
