How cheap can a cheap battery charger be?
Do all chargers except the very cheapest turn off when the battery is charged, or are there still some big expensive ones that don't do that, as for a golf cart? Or is the difference more subtle than that, and important?
That is, the people with the golf-cart (see follow-up post on that adjacent to this one) bought a new charger, mail order, from a site on the web that is about golf carts only.
The thing costs 360 dollars!, not what I would call cheap. But on its label it says, "Check the charger periodically to avoid damaging batteries. Initial charging rate should be [I forget, 15 maybe] and at the end the rate should be 2 amps." Does this imply they should turn off the charger when it's charging at 2 amps? Or it will damage the batteries? This is it:
The more expensive charger in the catalog they sent is about $455, and the first words in its description in the paper catalog are "Avoid over-charging batteries". Does that mean this one has auto-turn-off and the one for 360 doesn't? Or are they just not mentioning it for the cheap one to get people to buy the expensive one? Here's the expensive one:
You?ll get more daily power and extended life from your batteries.
- Features ?full float? charging capability, which holds your batteries at an appropriate voltage, ensuring that they're fresh and ready to go even after long periods of storage [If the cart is used every day 9-5, M-F, and never has long periods of storage, does this matter?] .... * LED status lights show the charging progress from 0% to 100% [it has 6 led's.]
