Quick Question On Battery Charging

Welcome! A 750 milliamp (.75 amp) to 2 amp microprocessor charger can float motorcycle/ATV/jetski batteries, or automotive size batteries. Some chargers are selectable, and some are gel safe, but this must be determined to avoid battery damage. Thanks for asking. . http://puchinet.com/quick-question/quick-question-on-ram.php

We at Chargingchargers.com deal with lead acid batteries in all their forms: flooded, Absorbed Glass Mat (AGM), and Gel. Now disconnecting the old resistor and connecting the new resistor the current will jump up for a few seconds and then decrease back down to around 0.6 amps so now you AnandTech Forums: Technology, Hardware, Software, and Deals Home Forums > Social > The Garage > Connect with us All About Circuits Home Forums > Electronics > General Electronics Chat > quick If I am charging an SLA battery using a constant voltage source and a resistor in series to limit the current (high wattage), how do I calculate the correct resistor value,

One test is worth a thousand expert opinions, but one expert specification is worth a thousand tests.

The Initial current of 2.1A will not be the same as the maximum charge current,, you would not normally charge continuously at the maximum Eric " Good enough is Perfect i know absolutly NOTHING when it comes to charging batterys. It depends highly on how much the 14.5v source changes, and this can lead to dramatic changes in charge current once the resistor values get small. Although the alternator puts out more than 2 amps, the r/r is sized to handle it.

I know what you mean about the delivery guy...**** them. If so, they probably have a spec sheet on it that gives charging information. #4 Like Reply Jun 21, 2007 #5 niftydog Active Member Jun 13, 2007 95 0 http://www.apexbattery.com/long-battery-wp412-battery-sealed-lead-acid-batteries-long-batteries.html Style Full Width Contact Us Help Home Top RSS Terms and Rules Privacy Policy.

AMG and flooded (wet) batteries can generally use the same charge profile, hence the frequent change in RV and marine applications to the sealed lead acid AGM types to eliminate the

True enough, but I still think it's a valid question. Had the camera the whole night on the USB port the first day only to find the next morning it was completely utterly empty. I assume current would be limited to around 0.5A with this value, but that's ok.

Some chargers differentiate between AGM and flooded with a switch, but most battery manufacturers have no problem with a flooded cell type charger or alternator as the charging source.

R=E/I >>> 14.5/1A = 14.5 ohms (closest value 15 ohms).

Just so we are all on the same page Regards, tvtech Fun and games are over. No, create an account now. Hmm, interesting. his comment is here If it stays solid red it doesn't charge.

So say you start with a 5 ohm 5 watt resistor. These forums are archived! Placed a 1ohm resistor in the output leg to do a bit of current limiting since the supply is rated at 1000mA. Ideally you want an active current limiter.

i found that 14.8v seems what it would like to be charged at, but i still don't know about the current. Not sure what's different about the way your bike is wired, but all of the wiring diagrams for the GS bikes show the output of the r/r going through the main The problem arises with a true Gel battery.

Latest: Rifter, Feb 22, 2017 at 1:59 PM Memory and Storage The hunt for illegals is on. The camera takes about 4 hours to charge so be prepared to wait a while on that. hopefully i can sneak out on my lunch break and take it for a spin. #7 joi, Jul 23, 2014 (You must log in or sign up to post here.) The discount store type battery charger, while possibly (probably) being microprocessor controlled, uses lower quality components and cooling methods, as they are designed with low cost and occasional use as their

There it gets disconnected from the rest of the bike, but it's connected to the battery all the time.

In the wire from the output of the r/r to the main fuse there is a branch that goes over to the ignition switch. there's a formula for charging batteries, but I forget it.
