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

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

Charge up to eight batteries at once.

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

Energize Milwaukee tool batteries with these chargers.

Recharge batteries for Makita tools.

Restore power to batteries for Dremel tools.

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

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

Attach these guns to a garden hose to fill batteries in hard-to-reach spaces.

Maintain the water level in multiple batteries.

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.

Protect batteries from dirt, debris, and water.

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.

Secure batteries to trays with these adjustable hold-downs.

Replace coiled spring contacts in battery holders and terminals.

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.

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

Connect these clamps to a wide range of wire sizes.

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.

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

Connect batteries in vehicles and generators.

Alternate between two batteries without interrupting power.

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

Stop corrosion caused by battery acid fumes leaking at the posts of battery terminals.

Replace worn and broken clamps on jumper cables.

These cables are for occasional use on cars and other small transport vehicles.

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.
