What does 6-DZM-20 mean?
3 Answers
6-DZM-20(22ah) is the model parameter identifier for a battery. The following is a detailed introduction to 6-DZM-20: 1. The '6' indicates: the number of battery cells connected in series, where one cell is 2V, and 6 cells in series form a 12V voltage. 2. 'DZM' indicates: a maintenance-free battery for electric power-assisted vehicles, which is a sealed battery for electric power-assisted vehicles. The '20' indicates that the 2-hour rate nominal capacity is 20AH, which is the capacity of the battery. 3. '20AH': mainly describes the discharge capability of the battery. For example, if the discharge current is 2 amperes, it can theoretically last for 10 hours, which is 20AH.
On electric vehicles, 6-DZM-20 is the code for the battery pack, which sounds quite familiar. The 6 usually indicates that there are six single cells connected in series, each being a 12-volt lead-acid type, like those used in electric motorcycles or scooters. DZM signifies that it belongs to the sealed valve-regulated lead-acid battery category, preventing leakage and being shock-resistant; the 20 indicates that each single cell has a capacity of 20 ampere-hours, meaning you should be able to ride over a hundred kilometers without issues, but the actual range depends on the vehicle's weight and road conditions. The entire combination reaches a voltage of 72 volts, providing strong power and quick acceleration, but you need to pay attention to charging habits to avoid over-discharging the battery, which can shorten its lifespan. If you see this label at a maintenance shop, it's best to check the production date and manual to confirm it's the original model.
I've personally driven a similar model, the 6-DZM-20 is probably that set of battery packs used for electric vehicles. The 6 indicates the number of battery cells, like there are 6 small batteries packed into the electric vehicle's chassis; DZM stands for their durability, with good sealing to prevent issues; 20 is the capacity of each, 20 amp-hours is enough for daily commuting. When I ride my electric scooter up a steep slope, I can feel the advantage of higher voltage—it climbs effortlessly, but you must use a matching charger when charging, as charging too fast can easily cause damage. Daily maintenance isn't much trouble, just clean the terminals. If the battery leaks or the voltage is unstable, replacing the whole set only costs a few hundred bucks—don't delay too long to avoid pushing the vehicle on the road.
