Even if the battery shows a good reading, there can still be an issue while it is attached to a load.So, whenever your TV or air conditioner remote control starts behaving funny, you can quickly take out your multimeter and start getting some answers. It should be evident that testing a battery using a multimeter is one of its easiest applications. It should fluctuate around 98.3, which denotes that the amperage is 100mA – enough to run the small PCB of the TV remote control #2 - Connect the test probes similarly as you did for voltage measurement and check the display. #1 - Select the DC current function using the dial and keep it at 200mA since we know that the amperage of the battery will be around 100mAh. In Part 2, we will measure the current of the battery. How to Measure Battery Amps with A Multimeter However, to ensure that it can supply enough current to a load, let’s also measure the amperage in milliampere-hour (mAh). In most cases, this voltage measurement of a battery is enough to understand that it’s working properly. #5 - For another (drained) battery, the reading looks like this Since this battery has been in use for some time, it shows 8.74V, which is still enough for it to supply current to the load. #4 - The display should read a value that is just short of 9V. #3 - Connect the test probes – black with negative, red with positive – to the battery and check the display Select DC voltage measurement for testing a battery #2 - We already know that the voltage of the battery is 9V maximum, so we will point the dial to 20V (as shown) i.e. Since battery generates DC power, we will measure DC voltage. To do this, use the switch dial to select DC voltage measurement. #1 - In Part 1, we will measure the voltage of the battery. How to Test a Battery Using a Multimeter? We will use a 9-volt radio battery for this guide. Set up a multimeter in a table along with the battery to be tested. How to Check Battery Voltage Using a Multimeter For a nine-volt battery, we will check both the voltage as well as the current. In our case, let’s assume the load is a TV remote control (RC). The basic idea is to check if a battery is capable of supplying enough amperage to a load.

He also said that Batteriser could one day partner with a Duracell or an Energizer and sell the batteries and Batterisers as a single package. Though Roohparvar says that his patents would prevent the battery manufacturers from simply adding the Batteriser technology into their batteries, he said he would be open to licensing the technology down the road. He also said that he has been talking to executives at Wal-Mart ( WMT) about selling the battery sleeves in the future. "The Batteriser is giving you lithium performance at alkaline price," Roohparvar said.Īfter an Indiegogo campaign in July for early-adopters, Roohparvar says the Batteriser will begin selling on Amazon ( AMZN) in the fall. And those rechargeable batteries are typically made of lithium, which isn't compatible with many battery-powered products. He said it's a cheaper solution than rechargeable batteries. At that price, Roohparvar, the technology "pays for itself" after just one purchase - a typical AA battery costs $2.50, and the Batteriser makes one battery last as long as eight. The Batteriser will come in AA, AAA, C and D-cell varieties and sell for less than $10 for a pack of four. home has 28 battery-operated devices inside. There are 5.4 billion battery-operated devices in the wild, and 15 billion disposable batteries are bought every year around the world. Roohparvar says he hopes to shake up the $14 billion disposable battery market. Roohparvar claims that the Batteriser can get 1,185 minutes out of a remote (5 times more energy), 570 minutes out of portable speakers (6x) or 355 minutes out of an RC toy (9x).īatteriser can continue to deliver a 1.5 volt charge from batteries that have actually discharged down to 0.6 volts. For example, a typical AA battery will stop working after 240 minutes of use powering a remote control, 95 minutes powering portable speakers, or just 38 minutes powering an RC toy.
