Panasonic DMW-BCM13 Review
Panasonic DMW-BCM13 is a genuine rechargeable Lithium ion battery which is compatible with an array of Lumix cameras from the same manufacturer. More specifically, it fits well with all Lumix compact cameras produced in 2013.
The battery has 3.6V and 1250mAh capacity, being compatible with Panasonic Lumix DMC FT5, TZ40 and TZ35. It uses DMW-AC5 AC Adapter and DMW-DCC14DC Coupler, measuring 1.6 x 2.4 x 4.9 inches. Nickel-cadmium had for many years been the exclusive battery suitable for portable equipment ranging from mobile computing to wireless communications equipment. Nickel-metal-hydride emerged along with lithium-Ion in early of 1990s and eventually became a promising battery combination.
Pioneer work on lithium battery started way back under G.N. Lewis in 1912, but it was in early of 1970s that the first non-rechargeable batteries of lithium were commercially available. The lightest among all metals, lithium has superb electrochemical potential, providing high energy density for its weight. Attempts of developing rechargeable lithium batteries failed easily initially owing to challenges with safety. Lithium metal exhibits inherent instability, especially while charging, which shifted research to non-metallic lithium battery which utilized lithium ions. Even though lower in energy-density compared to lithium metal, safety of lithium-ion can be ensured given certain precautions are met during process of charging and discharging. Sony Corporation in 1991 commercialized the very first lithium-ion battery, before other manufacturers began replicating this process.
Energy density of Lithium-ion is significantly higher than of standard nickel-cadmium and as such carries better potential energy density. Load characteristics are fairly good, behaving in similar manner to nickel-cadmium in discharge terms. High 3.6V Cell voltage allows designs of battery pack with just a single cell. Majority of mobile phone manufactured today operate on single cell, with nickel-based pack requiring three 1.2V cells in series connection. Lithium-ion is a battery of low maintenance, which offers advantage that most other chemistries are unable to claim. No memory or even scheduled cycling is needed for prolonging life of battery. The self-discharge is in fact less than half, when compared to nickel-cadmium, which makes lithium-ion favorably suited for modern applications involving fuel gauge. Cells of lithium-ion occasion little harm when disposed.
Lithium-ion does have its own drawbacks, even though it has some advantages. It is quite fragile, requiring protection circuit for maintaining safe operation. The protection circuit is built into each pack, limiting each cell’s peak voltage during charge, thereby preventing cell voltage from excessively-low drops on discharge. Cell temperature, in addition gets monitored in order to prevent extremes of temperature. Maximum charge plus discharge current on majority of packs is limited in-between 1C and 2C.Such precautions put in place imply that chances of metallic lithium plating occurring get eliminated, however.
