Hi Aaron, Does P=VI come into play ? Memory effect is also reversible to a degree by carrying out a few proper charge/discharge cycles, Self-discharge rate is very low at normal room temperatures, High temperatures during use or charging can cause the batteries to explode, although most feature adequate safety features to prevent this, High cost compared to other battery types, Very safe and rarely explode or catch fire, Loses significantly more capacity in cold weather than Li-ion, Worse for the environment than Li-ion due to much more mined material being required, Lose voltage slowly as they discharge resulting in less power, Lose the ability to be recharged if left discharged for too long. Battery temperature monitoring. misconceptions, a wbeaty QUORA.COM For example, Li-Ion batteries in cordless tools generally have a cycle life of 300-500. Also, if it's not already obvious, that's definitely not a 22.8Ah battery, just take a look at the size of a Ryobi 9Ah to get an idea of how big it really is.
