How to increase battery capacity without changing voltage?

Connecting multiple batteries in parallel is the easiest way to increase the capacity of your system without changing the voltage. The total capacity is simply the sum of all individual capacities.

How do I connect my UPS & batteries?

Thread the wires from the inside out, with the connection inside the case as shown. As noted in the parts list, you'll want to keep the wires short to minimize voltage drop, but long enough that you can place the UPS and batteries comfortably near each other and the device you're powering (computer, stereo, etc.).

How do you connect a battery to a cell phone?

Using battery cables, connect the positive terminal of one battery to the positive terminal of the next battery. Repeat this process until all the batteries are connected in parallel. Then, connect the negative terminal of one battery to the negative terminal of the next battery, following the same sequence.

How do you wire a battery together?

There are two ways to wire batteries together, parallel and series. The illustration below show how these wiring variations can produce different voltage and amp hour outputs. In the graphics we’ve used sealed lead acid batteries but the concepts of how units are connected is true of all battery types.

How do you connect a battery to a computer?

The first thing you need to know is that there are three primary ways to successfully connect batteries: The first is via a series connection, the second is called a parallel connection, and the third option is a combination of the two called a series-parallel connection.

How many batteries do I need to power my ups?

The batteries are in series in this UPS, so it requires 24 volts (black terminal connected to red terminal). Do not try to power it with one battery if it comes with two! Get two more ring lugs if you need two batteries. Since the battery / batteries will not fit into the old case, you'll use the lugs and wire to extend the wires outside the case.
