I was wondering if anyone knew what the best method for caring for your battery is. In other words, is it better to recharge it after every picture session even if it's not 100% discharged or should you wait until it's almost empty to recharge it. The second part of my question is whether the battery should be stored when not in use fully charged or discharged. Any help would be appreciated. Thanks
Some VERY good questions that I pondered myself. The answer is not at all obvious to me. Some barttery chemistries are better stored discharged (e.g. NiCads) while others are best kept fully charged (e.g. lead acids). Others will loose significant charge on storage (e.g. NiMHs drop about 3%/day) and are therefore only fully useful right after charging or when kept on trickle. I suspect that the Li Info system is about the best of all worlds and it's probably not critical how you use them. I have two and store one after full charging and keep one in the F505. I'll switch them when the one in the F505 gets low on a shoot, or sometimes just when it gets to be a month or so since the last switching.
The Sony battery for the F505 is the info lithium type from Sony. Since its lithium you don't have to worry about the memory effect of the older technology. The battery has a chip that will regulate the amount of charge the battery needs. It will stop charging if the battery is full, so you can charge it at anytime. You should store it fully charged from what I've been told, if it for extended period of time. For short interval it should not matter.
