Once a day for IB3800?

[Batfish]

I've always gotten a kick out of this question and the way it's approached. If someone can find where the timer and/or clock is in a sub-c battery, please show me a picture :)
Batteries have no idea what time it is, what day it is, or even what millenium it is. All the batteries care about is how hot they are. If you let them cool down to ambient temperature between uses, they will most likely last for the amount of cycles that the manufacturer has rated them. The reason I say "ambient temperature" is that you can't really let your batteries cool to 70F when it's 90F out. At the same time, you don't need to let them cool all the way down to 50F just because it's colder where you are.

The information I have read at various places over the past couple years comes down to the following for the nimh sub-c cells we currently run:

For racing purposes , packs charged at 5A will have good punch and performance for 25-50 charges. After that, they are good for practice packs up to about 100 charges. After about 100 charges, they become bashing packs.

For bashing purposes, packs charged at 5A will have good results for about 200 charges and may even be acceptable for quite a bit more.

A lot of the information that people run with is information from sponsored drivers running at national events. This represents less than .1% of the people using these batteries, and should not be taken as gospel for those looking to get the most out of their $. Many of these drivers will run a weekend of racing on a couple packs they got from a sponsor, then get rid of the packs before the next big race. Taking their advice for the best performance is great if you're also running "disposable" free packs, but doesn't make much sense if you actually pay for your own batteries and need them to last.

Follow the manufacturers guidelines for charging rates and make sure your packs are cooled to ambient temperature before re-charging, and you'll get the best life out of your batteries, regardless of how many times you run them each day.
