I've bought two packages of low-self-discharge nickel-metal hydride AA batteries, each made by a different well-known battery manufacturer.
Sadly, the datasheets aren't very detailed:
• One datasheet is just a single page long. It says that I should charge the batteries at between 0° Celsius and 40° Celsius. But it says nothing else about charging, let alone trickle charging.
• The other datasheet is two pages long. It discusses charging at a charge rate of 0.1C. It also discusses fast charging at 0.5C or at 1C. But it doesn't mention trickle charging at all.
Let's assume neither brand of cell has any gas-recombination capabilities. When a battery is fully charged, may I trickle charge it? If so, what's the maximum charge rate I may use? I don't want to damage the cell.
