After the battery is fully charged, these chargers continuously provide a low-level charge to maintain the battery without overcharging.

Small enough to carry, these charger/starters provide a 125-amp starting current.

Once fully charged, these starters store enough power to jump start a battery multiple times.

Bring batteries to these chargers for maintenance.

These chargers are for use with most DeWalt batteries, except Univolt batteries.

Restore power to batteries for Dremel tools.

Use these chargers with Black & Decker batteries.

Drain slots on these trays prevent fluid accumulation.

Protect the connection point of 9V batteries with these caps.

Pins fit around battery clips to hold them closed and prevent batteries from coming loose.

Add distilled water to wet-cell lead-acid batteries to maintain performance.

Replace chargers, hose, valves, and switch panels in battery water-filling carts.

Flip open these caps to check the water level and fill a wet-cell lead-acid battery.

Protect batteries from dirt, debris, and water.

Also known as battery reamers, these tools spread open a battery cable clamp and clean the terminal all at once.

Cover battery terminals to protect against corrosion and short circuits.

Connect these shunts to a battery and a panel meter or electrical testing device to measure the current flowing through a circuit when the current is too high to be measured directly by a meter.

Use a 20-volt DeWalt battery in an 18-volt DeWalt cordless tool.

These batteries are compatible only with Milwaukee tools and chargers.

Replace batteries for Makita tools and chargers.

Designed for use with industrial battery cable and battery charger cable, these connectors can be used with vehicle batteries.

Made of lead, these clamps resist corrosion to stand up to marine environments. Use a lug to attach your cable to the stud.

When heat is applied, the flux and solder mixture creates a metallic bond that is nearly twice as strong as crimping or compression connections.

Insert your stripped cable into the compression nut and tighten; no crimping or heat is required.

Thicker walls than standard battery terminal lugs make these more durable.

Insert your stripped cable into the compression nut and tighten; no crimping or heat is required.

Connect batteries to each other or to electrical systems.

Test large engine batteries that draw up to 500 amps. Turn the dial to vary the load applied to the battery to see how it performs at different loads.

Apply a fixed load to small engine batteries that draw up to 125 amps.

Alternate between two batteries without interrupting power.

Neutralize acid and clean away corrosion.

A compact and economical alternative to standard battery terminal crimpers. Hammer the top of the pin to crimp.

Thicker wires allow for a fast start on large trucks and industrial vehicles.

Replace worn and broken clamps on jumper cables.

Check the condition of battery fluid by measuring its density to indicate the state of charge.

For use in enclosures and panels where components require battery power, these enclosures have contacts for AA and 9-volt batteries.
