After charging a battery, why does the charge amp hours reported significantly exceed the battery amp hour rating?
• Most batteries require more charge to be put into the battery than can be drawn from it. Most new high quality batteries are rated conservatively and thus can accept and deliver more charge than the nominal amp hour rating. The battery parameter table used may have an entry error. There may be a parallel current path with the battery which, in constant current mode will extend the charge termination time, or, in constant potential mode will increase both the current drawn and extend the charge termination time (ie: a defective CASP discharge circuit or a battery still attached to an operating device). Q: Does CASP “handshake” with their serial Epson compatible printers? A: Handshaking is user selectable and is determined by the Printer Code in Table 099, 7th item, first bit. If the first bit is “0”, no handshaking occurs. If the first bit is “1” then full RS-232 handshaking is enabled. The latter is the recommended condition, particularly if the user is printing all of the battery pa
