Where is the cheapest place to snag UPS batteries. I need 2 bp7-12 for my
Cyberpower 900AVR. It is in warranty, but I'll be hanged if I can find the
sales slip and such. I did a google on it, but I don't know who is reputable
and who is not... I don't want old batteries, but I don't want to pay the
price of a new supply for them either.




Thanks

I bought some from www.batterywholesale.com last year for an old APC UPS
450. Still kind of expensive though because of the shipping.

If I wasn't stubborn I'd probably just wait and get a better UPS for cheap
during the Christmas sales.

I have a UPS that requires 12v, so I have mine wired externally wired to s
deep cycle marine battery. One summer day last year I stayed online for over
6 hours while the house power was off!

Does the UPS charging circuit handle the larger battery OK ?

What is the VA rating on the UPS ?

During charging, measure current flow into the regular battery and
compare that with current flow into the larger battery (but only if
you know how to use a multimeter). If the current flow is the same,
it's probably OK. I think current would be determined by something
called the internal resistance of the battery.

It's a good question, in my opinion.

Ordinarily, the charging circuit would vary charging time according
to how discharged the regular battery is and that time would vary.
Circuit specifications should max out at a certain point after
charging begins. I think it's just like, for example, when you fill
your car gasoline tank. How large your tank is doesn't matter unless
the the gasoline station gas is limited, but that is like suggesting
your house current is limited which it isn't.

Others might know better, especially in (sci.electronics.*) groups.
I think you should ask there if you really want to know. Please
report back the conclusion of any significant discussion.

Have fun.

It's on and APC 650w unit. Bigger batteries just take longer to change than
smaller ones. If the charger inside the UPS is anything like most hi quality
chargers then it monitors voltage to know when the battery is fully charged.
I think it functions more like a float or maintainer charger that can be
left on forever without cooking the battery.

Chargers are specific to the battery chemistry and a mismatch can kill
the battery. I'll guess that the original were lead gel cells and the
marine battery is lead acid. CLose enough, and cheap.

Check to see if there is a Batteries Plus in your area. Take the UPS unit
to
them and they will replace the battery for you. Same with your car, truck
or
whatever that needs a battery.

I live in Tampa Bay Florida. The US is a big place.

The float voltage for the gel cells in the UPS will be too high for the marine
battery. Be sure to check the water level frequently and expect that it will
require frequent refilling with distilled water. For a specific example, I have
several APC SmartUPS-XL that allow external battery packs to be connected. The
battery voltage is nominally 24V. These units float the battery at 27.8V, or 13.9V
for each 12V battery. The marine batteries should have a float voltage of 13.2 at
that temperature.

eBay is a good source for these batteries. Shipping is expensive but the overall
cost may still be reasonable. I have bought somewhat bigger batteries from one
eBay seller in Texas, Gruber Power Services, and it was still a good deal sending
them to California.

One thing - when you change the batteries, be sure that the UPS is unplugged from
the wall and turned off. Some UPS designs do not have isolation between the
batteries and the AC line input.

Try Batteries Plus. Look in the phone book. They are a national chain.

you can buy the laptop battery from the site: http://www.laptopbatteryoff.com/

The metal laptop battery connections from 2 to wipe with a damp cloth every three months in an alcohol solvent. This will become more efficient power from a Compaq Presario CQ62 battery. No longer stand while charging the battery on laptop, at least two to three times a week should be used. Lithium ion batteries do not discharge it completely.

the HP Pavilion dv5 Battery have limited battery life. This lifespan rely on its use as well as its maintenance. but how?

Deep cycle batteries, also known as gel cell batteries, are commonly found in wheelchairs, radios, and motorcycles. They are considered "premium" batteries, since they do not deteriorate in extreme heat or coldness. They also have the unique property of not spilling or leaking. You will have to purchase a specially made gel cell battery charger to charge this type of battery. There are three cycles in charging a gel battery: bulk, absorption, and float.
1.Read your battery label for any details concerning charging. Find the amp-hour rating and voltage.
2.Look through the manual for your deep cycle charger. Every one is slightly different.
Plug in the charger and set the voltage to match your battery. If the battery has no voltage information on it or is hard to read, set it to 10.5 to 15
volts. This is the "bulk charge" stage.

4.Place your battery into the charger, or hook it up so that the positive cable goes into the positive terminal, and the negative cable connects to the
negative terminal. If there is another dial to indicate a deep cycle battery, turn it on.
5.Wait for the charger to change over to the "absorption charge" cycle. Voltage is between 14.2 to 15.5.
6.Wait for the battery to change over to the "float charge" cycle, where the charge goes down to 12.8 to 13.2 volts. You have two options when you see the voltage go down. You can turn off the charger, unplug it, remove the battery and place it back into your device. Or, if you are not going to use the battery right away, you can let it continue charging indefinitely. This cycle will not end unless you turn the charger off.
