Yes, it mAh or Ah is how long the battery lasts, it does not affect performance.
yes a 5ah battery is a longer working battery than a 4ah so it is actually better than the 4ah
Yes, you can replace a 4Ah battery with a 5Ah battery, as long as the voltage and connector types are compatible. The 5Ah battery will provide a longer runtime, as it has a higher capacity. However, ensure that your device can handle the increased capacity without any issues, as some devices may have specific requirements or limitations. Always consult the manufacturer's specifications before making a replacement.
Its a 12 Volt System. The Standard battery is 4Ah
I'll answer my own question since no one answered it. I replaced the 2 pcs. 12v 4.5ah battery w/ 2pcs. 12v 4ah battery. It seems alright since it is now working fine for at least 2 months w/ 1 PC connected to the UPS. What I'm concerned though is that the UPS will overcharge the batteries since the replacements have a lower ah rating. --------------------------------------------------------------------------------------------- The charging will be fine - it is how long the UPS will run for (if you mains cuts out) that has been affected by your replacement.
http://www.batteryinternational.com/lantern-battery.html is a good site to find replacement batteries specifically for lanters. Otherwise you can call 1-877-28-BATTERY and they can help you find the battery you are looking for.
Ah means Ampere hours. A 4 Ah battery can release 4 amps for one hour, or 1 amp for 4 hours, or 0.5 amps for 8 hours, or 8 amps for 0.5 hours.
Energy = 4Ah x 3600 seconds x 12 volts = 172,800 Joules
First find the current which is 250/12 = 21A rounded off. So you would need 6 of the batteries in parallel to get a bit more than 1 hr and probably 11 batteries in parallel would provide around 2 hours of operation. This is not precise since the power supply wouldn't always consuming 250 watts of power.
I assume you're assking about a 4Ah(ampere-hour) battery.How long it'll last depends on the drain.If the drain is 1A it'll last 4 hours.0.5 A, 8 hours2A, 2 hoursetc, etc
The Longbo Chopper model LB49GS-2 typically uses a 6V 4Ah lead-acid battery. It's important to check the specifications in the user manual or consult the manufacturer to confirm compatibility, as battery types can vary based on production runs or modifications. Always ensure proper handling and disposal when replacing batteries.
The first choice was the best: 3 x 12 v 12 Ah will give a 36 v 12 Ah battery. In series the same current goes through all the batteries so the Ah capacity does not change.
That depends on the characteristics of the battery. The numbers you quote don't give enough information. 4 Ah is simply a measure of the battery's total energy storage (for rexample, 1 ampere during 4 hours, at the specified voltage), not of how fast it can be released.
