    Battery Tender call them as I did last Friday, r.e. my 9-10 yr old unit. Sales mgr,John says it will be $12-45 for another depending on repair needed. Thats cheaper than a new one & back in warranty too. I also sent him 2 ea. $125 waterproof Tenders that had quit. He said they are non repairable & when I quized him as to why the shorter warranty compared to much longer on the cheaper unit he said it was based on them being non repairable as permanently sealed. Told me to send them back even though out of warranty & I'd get new ones for a $30 per unit warranty exchange fee. Not such hard people to work with.
    Wow, I am impressed. My comments were based upon the many reviews that I had gone over during my charger search. People complained that it cost as much to exercise the warranty as to purchase a new charger. I guess that is what happens when you buy the entry level product.

    You know, it is great to hear about good customer service for a change. Like my local BMW dealer offering to re-key my top case for free. Sometimes it does not take much to make a customer happy.

    I have a couple of those Die Hard battery charger/maintainers... I use them for my cars (standard wet-cell batteries) and on my Panasonic AGM battery for the bike. I've left them connected for up to 10 weeks on the Miata, but I've not had a need to do so with the bike, just the weekly, overnight top-up. No problems so far (2+years)... although now that I've written this I'm sure all of my batteries will be fried by the time I get home this afternoon!

    I had bought one of those Wally World $17 "battery tenders" before I bought the Delran. Hooked it to a garden tractor battery and it took it about a month before it fried it. Gave it away and bought the Delran. Pay a few more bucks and get a good one and you won't be sorry.

    Biggest retailer in America (the world?), virtually everything they sell which isn't a name brand is crap, yet people keep buying from them because its cheap. I don't get it.

    Pardon the thread derail.

    I know one thing, I got it..lol...won't happen again though, I have an aversion to Wally World anymore and don't go into one unless I can't find it anywhere else. Hasn't happened yet.

    You can't even trust the brand names without careful checking. I was working an insurance claim where the suspected cause was a Magic Chef appliance. I wrote Magic Chef to put them on notice. They wrote me back to inform me that they had sold the name to Walmart who put in on an appliance made in China. I contacted Walmart and they confirmed the information and told me who in China supplied. I was thankful that the fire was operator error rather than eqipment failure so I didn't have to fight the battle of Walmart and China.

    I also discovered a 26" RCA TV I bought from Walmart was not made by RCA when the Dish remote would not program for the TV. I discovered it was made by an unknown company when I read the warranty.

    You usually find that on the packaging of chargers, except instead of the word "Perfect for" (which is a lie), they use "Charges" which is sort of true, but they fail to tell you that it'll affect the life of your battery.

    But since your average Joe is happy with five-year battery life (talk about a short life for a battery), nobody bothers to get into the details of battery chargers.

    Sorry to say, most of them are worth what you pay for them...no more.

    Over the years on motorcycle forums, I always read about people plugging their bikes into battery tenders or chargers when not in use, the correct chargers you MUST use, etc.

    I've never done it on any motorcycle I've ever owned. Maybe I just ride them all frequently enough so that it's never been an issue?

    I got 9 years out of my Yuasa lead acid battery. It was still functional, but I replaced it because I was going on a weekend trip. So far, on my sealed battery, I'm on year 6 with no signs of slowing down.

    I use my cheap charger twice a year; in the late fall when putting the girls away for the winter, and in the spring, when waking them up. In between I just ride, and frankly, I'm very satisfied with the life of the batteries I use. My motorcycles usually are idle the months of December, January, and February here in Minnesota, and usually get "woken up" some time in middle or late March.

    Honestly, it works just fine for me, so I'll keep doing what I'm doing.

    In fact, a better charger is one that does not go into "float mode", instead, one that properly tops up a battery in the absorbtion mode and then switches off till battery voltage drops down to ~12.7V where it switches back on again and the cycle repeats.

    Both of my CTEK 3300 chargers do that even though they are advertized to do 3-stage charging...all the better.

    My factory Exide battery in my oilhead GS would sit at 12.9V for at least 3 weeks till my voltmeter display would show 12.8V.

    I just walk by my GS now and then and check the reading on the dash...

    Its a good idea to at least monitor battery voltage while it is parked, even if the battery is disconnected. If you have any standby current draw, then disconnecting the battery is a must.
