If you need 100 milliamps current, then you can run for 5000/100 = 50 hours. If you want to discharge in 10 hours, you can get a current of 5/10 = 0.5 amps. For example a 5 amp hour battery is the same as a 5000 milliamp-hour battery. Divide by hours and you get amps, divide by amps and you get hours. In closed cabinets some provision for ventilation is necessary to prevent hydrogen gas from accumulating.Ĭell capacity is rated in amp-hours or milliamp hours. Some method of releasing or absorbing the hydrogen, flooding with air or inert gas should be used. Take this into account if you are designing a closed system, such as waterproof lights, weatherproof installations, etc. Over the course of life most batteries release hydrogen, and sometimes oxygen. These can be custom designed for every application. The most typical type of protective battery cases are injected molded plastic or steel cases. This table gives examples of the resistance of nickel spot weld strips.

It is strong, has very good corrosion resistance, and will not oxidize easily. Nickel is fairly low resistance, yet has enough resistivity to be spot welded. Nickel foil is used to spot weld packs together. Some customers specify which adhesive is to be used that they believe will improve the performance for their specific application. There are several standard adhesives that are used to connect the batteries inside the pack that are standard in the industry. The ends of the lead wires are usually connected to connectors specified by the customer to match their requirement for connection to the device. These components are connected in a direct line circuit to the battery. Thermal protectors (thermistors) are typically used to prevent overcharge and overheat.
