Memorized batteries
My JVC BN-V438U Lithium-Ion Batteries (7.2v, 3800mAh) for JVC GY-HD100,
were bought three years ago, and now they are giving me short time of work. My colleges toll me they are "memorized" and don't receive the full charge. Questions: 1. Is there a way to clean up the memorize fenomenon? 2.How to evoid it in the future if I can clean up them or with new ones? Thanks.

I was also thinking that only Ni-cad had memory issues. LI's will wear down, but they shouldn't ever need to be completely depleted (and I believe that should actually be avoided) to solve a memory issue.

Before I got an IDX system I picked up some extra Impact batteries from BH for about 50% the price of the JVC ones. A little more power too. Impact makes several batteries. $49.95 gives 3200mAh's compared to the stock battery of 2800mAh's. Pick up a couple and give yourself some breathing room. They should last a little more than an a hour with LCD open and using the zoom, Just long enough for a 63 minute tape and some standby time.
These days I'm running an IDX system that I'm happy with it. 4 or 5 hours runtime out of the IDX battery, but for the price, it's hard to beat picking up 4 of the Impact batteries. |

If you want to stay with the JVC little batteries, I bought extras from this guy on ebay at $16.22 each. They are 3400mah, last about an hour and they work fine, I have five of them and have used them for almost a year now. Ebay Item#13021101024
I think Li-Ions don't have memory, they just wear out. |

Lithium Ion batteries do not suffer from a memory efect. They do however have both calendar life and cycle life. They will loose capacity as a function of time and as a function of the number of charge-discharge cycles. The higher they are charged and the deeper they are discharged, the shorter the cycle life. Li Ion batteries like shallow cycling.
Temperature will also have a dramatic effect on life. Best, Michael |
