the best batter charger for your lead-acid battery?

Lead-acid battery charger

Lead-acid battery chargers are available by battery warehouse Intercel. For each lead-acid battery, we offer the right lead-acid battery charger. Lead-acid battery chargers from 6V to 48V in a variety of amperages can be delivered for a variety of battery applications.

Lead-acid battery charging technology

Most lead-acid battery chargers have significant 60 or 120 Hz ripple and noise, others used pulse charging technology. This causes havoc with systems such as audio systems that would like a nice, clean voltage. These lead-acid battery chargers are designed to charge a battery at high power, but very quietly.

Lead-acid battery charging; three charge stages

Lead-acid batteries should be charged in three stages, which are [1] constant-current charge, [2] topping charge and [3] float charge. The constant-current charge applies the bulk of the charge and takes up roughly half of the required charge time; the topping charge continues at a lower charge current and provides saturation, and the float charge compensates for the loss caused by self-discharge. Figure 4-4 illustrates these three stages.

Tips for charging lead-acid batteries

Charge your lead-acid battery in a well-ventilated area. Hydrogen gas generated during charging is explosive.
  | Choose the appropriate charge program for flooded, Gel and AGM batteries
  | Charge lead-acid batteries after each use to prevent sulfation, do not store on low charge.
  | The plates of flooded batteries must always be fully submerged in electrolyte. Fill battery with distilled or de-ionized water to cover the plates if low. Tap water may be acceptable in some regions. Never add electrolyte.
  | Do not allow a lead-acid battery to freeze. An empty battery freezes sooner than one that is fully charged. Never charge a frozen lead-acid battery.
