D Size R20P R20 D UM1 Super Heavy Duty Battery 6 Pack

Product Information

Most sizes are uncommon today; however, the PP3 size (and to a lesser extent PP8, used in electric fencing, and PP9) is readily available. Same diameter as AA battery, used in small electronics, including pulse oximeters, as well as use in some computer models (such as most pre-Intel Macintosh models and some older IBM PC compatibles) as the CMOS battery. Introduced by Sanyo/Panasonic for use in portable power tools as higher-power and higher-capacity successor for 18650 cells. With the new Empulse R20 pushing aid it has never been so easy to support the attendant pushing the wheelchair.

Rechargeable nickel–cadmium and nickel–metal hydride are far less common than other rechargeable sizes. Cells less than one centimeter in height are assigned four-digit numbers, where the first two digits are the diameter in millimeters, while the last two digits are the height in tenths of millimeters. However, 2CR1/3N, a 6V battery consisting internally of a stack of two CR1/3N and standardized by ANSI as 1406LC and by IEC as 2CR13252 (though some datasheets state it as 2CR11108 instead), is sold by Duracell (PX28L [155]), Energizer (L544, now obsolete [156]), and others. As well as other types, digital and film cameras often use specialized primary batteries to produce a compact product. Often used in pairs instead of CR2032 for devices that require more than 3V, like blue/white LED flashlights.g., the Western Electric 'Blue Bell' KS-6456 printed in blue ink on a grey paper and the Eveready 'Colombia Gray Label' printed in red ink on grey paper. A rare battery, sometimes used in car security (car alarm/keyfob batteries), organizer (backup battery for PDA such as Psion etc. Used in keychain LED flashlights, and in some digital cameras to keep the time and date function running even when the main battery is taken out of the camera.

Combining a unique folding function, the lightweight R20 is under 5 kg providing easy transportation and literally no impact when self propelling your wheelchair. The complete nomenclature for a battery specifies size, chemistry, terminal arrangement, and special characteristics. Taller cells are assigned five-digit numbers, where the first two digits are the diameter in millimeters, followed by the last three digits indicating the height in tenths of millimeters.The easy to use control system has one push button to go, as well as an easy to read display showing the speed and battery gauges. A height adjustable handle allows the user to achieve the most comfortable position when operating the device. The full battery designation identifies not only the size, shape and terminal layout of the battery but also the chemistry (and therefore the voltage per cell) and the number of cells in the battery. LiFePO4 properties: long lasting (2000+ cycles), safer, more stable, good continuous/peak discharge rates (3C/10C), less energy dense.

The Headway 38120HP cells are used in high discharge environments as they have very good continuous/peak discharge rates (10C/25C). Since LiMnO 2 cells produce 3 volts there are no widely available alternative chemistries for a lithium coin battery. More common as a NiCd or NiMH cell size than a primary size, popular in older laptop batteries and hobby battery packs. A rechargeable lithium-ion version is available in the same size and is interchangeable in some uses. Such 9V batteries in a single package do exist but are rare and only usually found in specialist applications; they can be referred to as 3CR1/3N.

Many of these were sold as B batteries for early transistor radios (before their function was replaced by the 9-volt PP3 battery). The R20 contains 250w brushless motors that don't wear over time versus traditional brushed versions, as well as a powerful, robust and long lasting tyre and a lithium ion battery ensuring a durable and reliable product, this is reinforced with an extended 2 year warranty on the battery and 3 years on the motor. To be eligible for a replacement, your item must be unused and in the same condition that you received it. A matrix of the required docking arm length is available in the parts manual (section documents) or on the web page. The R20 can achieve a 9 mile range, as well as having the ability to climb 5cm kerbs and 10 degree slopes.
