Wireless Battery Charger Buying Guides

Some electronic products need a specific format wireless battery charger. This is usually supplied by the manufacturer. A typical battery charger can charge between four and six batteries.

You should always have at least one pair of fully charged batteries in your car. Make sure that the wireless charging for furniture can take the load.

Battery chargers without an "end-of-charge control" should be avoided. Too much current can cause battery damage in a matter of hours. You should never leave an unregulated, or "automatic", charger connected to your battery for more than 24 hours.

Charger control is one feature that's worth the extra expense. A high-end battery charger comes with an intelligent microprocessor that switches off the wireless charger when the batteries have fully charged.

It can detect how much charge was in the original batteries and add only what is needed. On the other hand, cheaper chargers charge batteries for a limited time which can cause overcharging and reduce the battery's life. An LED light is used to show when the charge cycle has ended.

The charging current needed to fully charge the battery will determine the size of the wireless battery charger you choose. The battery capacity is measured in Amp Hours. This is the value used to calculate the battery's life between charges.

When charging, you can connect multiple batteries in a series or parallel configuration. Keep in mind that your battery charger speed is limited to a certain charging current, depending on which model you choose. This limits how many batteries you can recharge at once.
