    That's high. Try to get your next one for around $30. Costs the shopkeeper $22.

    I have both 6 volt & a 12 volt jr models, used on cars that haven't moved much lately.
    Work great, & cost somewhere around $20.00 each.

    You will find that circuit is in all the good quality units.

    I still have a dark ages trickle charger and often use it just to get a battery started then put the tender charger on it.

    Exactly the same here. Three in use here for about 4 years.
    Prior to that I had several batteries fail after a year or so of sitting even with cables disconnected.
  8. I ve used em for years n saved money on batterys for years too! Harley batteries last 3yrs most and mine lasted for 10 n was still good but needed to update!
  9. I grew up hearing this (and telling others the same) but learned in A&P school it was a falsitude. Sitting anywhere is bad, the concrete has nothing to do with it.
    (Thanks to Ron Nulph for setting me straight on that one).

    Anybody used the HF one on 6 volts? Most of my cars that wait through the winter are 6 volt..

    Hook 2 six volt batteries in series and use the 12 volt maintainer.

  12. I have several Deltran battery tenders on everything that does not get driven often.
    I even have a Jr. model on my JD mower. 6 yrs on the mower factory battery so far. 12 yrs on an Optima in an OT car. I swear by them.

    I swear by them. It's a must for motorcycles. I have one on my 39 Ford. I got 10 years out of my battery. I bought a new battery last year. The guy who sold me the new battery was shocked.
