How to Maintain Your Battery

Cheers Arsey, thats a good article, thanks for posting.
To add to that article, just because a battery is showing volts across the terminals doesn't mean it can fully deliver power like is was when new.
Batteries degrade naturally over time (depending how they are used/maintained) and the only true way to know if a battery is still good or not is to use a load tester (aka drop tester). This puts the battery under a brief heavy load and analyses how much sustained power it can deliver.
Load testers have become pretty inexpensive to buy, I got one recently (built in to a car OBD scan tool) and it condemned as scrap a handful of spare batteries I had a spares that I thought were okay.

Interesting article. didn't know you can't jump start a lithium Ion battery.
The Lithium charger I use has to detect voltage in the battery before it will charge. So a flat lithium battery will have a problem. I got around this by connecting one of those small 9v radio batteries in parallel when connecting the charger. The charger then detects some voltage and starts charging, you can then disconnect the 9v battery.
