<div> <font size="3">The old style chargers MUST be monitored, especially with newer batteries. If you leave it hooked up too long you will boil off the electrolyte. How long? Depends on the state of charge. What is the state of charge? Is it 50%, 25%, 75%? You can figure that out if you take an open circuit voltage reading, adjust for temperature and look it up on a chart. Then guess how long to set the timer.</font></div>
<div><font size="3"><br>
</font></div>
<div><font size="3">Or take a voltage reading periodically and don't forget to turn it off. <br>
</font></div>
<div><font size="3"><br>
</font></div>
<div><font size="3">Yes, the alternator doesn't do the three-phase charge regimen but it does regulate the voltage to 14 volts. The old school chargers are just a transformer and a rectifier and when the battery achieves full charge the voltage will continue to rise and boil off the electrolyte. The smart chargers will self-regulate to prevent that. But if you want to babysit you charger by all means knock yourself out.<br>

<div><font size="3">I am in the business of battery powered transport devices for medical equipment and patient transport and we use a lot of chargers to recharge the AGM batteries we use to power the devices and they work quite well and are well suited to the end users who will just plug them in and walk away for the weekend. An old-school charger just simply will not work for us.<br>

<div dir="ltr">I agree with Bill - get a conventional style next time, if you can find one. Even my local NAPA man said to buy an old charger and have it repaired rather than buy a "new, improved, new technology, it's faster, more efficient, easier, etc., etc." type of charger. I laugh when I see newer, fancier chargers with all of these different settings that recognize all of the different battery types - does the vehicle's alternator have all of those settings????<br>
</div>
<div dir="ltr"><br>
</div>
<div dir="ltr">Use an old style charger and just monitor with a volt meter. <br>

<div dir="ltr">Call the manufacturer and ask them if it is telling you if a known good battery Is bad. <br>
</div>
<div dir="ltr"><br>
</div>
<div dir="ltr">If it’s like my new Shumacher(sp?) charger it require some juice to work. If the battery is 100% flat, it won’t see it. Also, you cannot use as a power supply while bench testing anything. It does have the Reddit’s that tell you what the voltage it or the percentage of charge. <br>
