I have a 12volt AGM 32ah battery being charged by a Guest 2606A Battery Charger (connected to 110v AC. I have a Cen-Tech 750 watt power inverter also attached to the battery.Can I run a small radio and a light off the inverter while the charger is also attached to the battery. The battery is showing full charge. Thanks, Mel
Yes, but a slightly depleted battery will take longer to reach full charge if the current is being drawn from it.... although if it's an LED light and efficient radio the current draw will be almost negligible or hardly enough to notice.
but why would you want to run mains electrical items from a battery that's plugged into the mains?
it's much more efficient to use mains electrical power for your devices until there's a power outage (this is where the inverter is really needed) or you need mains power in the middle of nowhere.
if you absolutely want to go down this route maybe an old UPS would come in handy, it will continue to output mains power in the event of a power outage.... just connect your battery in place of the old dead one (your 32Ah won't fit in the box, just use heavy cable) UPS boxes hold a 12v battery, it's a simple hack.

There is a contact in the upper left hand corner of the batt compartment.This has to touch the metal of the last batt.If your batts have paper around them scrape it off where it contacts that contact point.

I have a background in electronics so i hope i can help. Now after reading this i have the feeling this item does not put out 2000 watts cause if that were the case it should draw somewhere near 147amps. This is because to find out amps you need to take the 2000 watts and divide it by 13.6 volts (assuming what the vehicle runs at) that gives you amps. watts/volts=amps.

hi thanks for using fixya!!
Is your laptop is brand new? Try to remove the battery. Then, try using your laptop and AC adapter without the battery, you will get the power supply directily from AC adapter. If it works properly, then its okay. Now, try to install back your battery then try to charge it. If not charging, perhaps you need to buy a new battery. However, I suggest you bring your laptop to a service technician to further check the error, before you purchase a new battery.
If you need further assistance, let me know!

Your numbers don't add up. Where are you 'seeing' 200volts. Your lap top power supply transformer uses 120 volts AC. Are you plugged into a 240 volt outlet or something? Your inverter should be 12 or 24 volts DC input; to AC power usually 120 volts AC. Check out you output plug, should read 110 - 120 volts AC

Inverters use high power transistors to create an A/C voltage from a D/C input. These transistors are the common point of failure when the units are not cooled properly or used beyond their rated capacity. (Actually, you should always buy an inverter that’s rating for continuous use is well below what your actual need is). What’s most likely happened is that these have shorted out and need to be replaced. Unfortunately, replacement parts alone will likely cost nearly what a new unit costs.
Sorry to be the bearer of bad news; but you basically have a nice paperweight with some pretty lights and fans on it.
