Battery charging

Exercise caution with all batteries, never leave charging batteries unattended.

NiCad and NiMH - Typically charged from a constant amperage/variable voltage charger. Popular chargers include models from Astroflight and Triton. These chargers can handle high-voltage packs (up to 32 cells, depending on the model), but require a separate high-amperage DC power supply. For smaller packs (12v and below) many 'sport' chargers can be used, like ones for model airplanes and cars. To get the most from your packs, get a peak charger, rather than one that works on a timer. These types of cells also become noticeably warm when approaching full charge.

Lithium - Although very light and compact for the power they deliver, lithium packs require extra care and a special charger. Some high-end chargers have settings for both lithium and NiMH/NiCad, but you may also purchase specialty chargers for lithium only. Lithium batteries have a much higher tendecy to overheat and even catch fire if mistreated. Always charge the batteries in/on a fire-proof surface.

Lead-Acid batteries - Generally are the easiest to charge. There are many automotive chargers available, in addition to specialty chargers like the Battery Tender line, and the SLA function on the Triton. Some high output SLA batteries like Hawkers require a high amperage, constant voltage power supply for proper charging.

Again, use great care and follow the manufacturer's instructions when charging batteries.
