How should I charge my power tool battery for the first time?

For the best performance, fully charge your new power tool battery before using it for the first time. Always use the recommended charger designed for your specific battery type (NiCd, NiMH, or Li-ion).

How do I extend the lifespan of my power tool batteries?

Store batteries in a cool, dry place. Avoid leaving them in extreme heat, cold, or direct sunlight. Do not overcharge or fully drain Li-ion batteries; instead, recharge them before they reach 0%.

How often should I recharge my batteries?

Recharge your batteries whenever performance starts to slow. For NiCd batteries, occasional full discharges can help prevent memory effect. For Li-ion and NiMH batteries, partial recharges are best.

What is the warranty period for replacement batteries?

All our replacement batteries come with a 12-month warranty and a 30-day money-back satisfaction guarantee.

Can I use my original charger with replacement batteries?

Yes, our replacement batteries are fully compatible with the original OEM chargers designed for your tool brand and battery type. Always double-check the specifications before use.

Power Tool Battery FAQ - Usage & Maintenance

How should I charge my new power tool battery for the first time?

Charge it fully before first use. Always use the original charger or a compatible replacement designed for your battery chemistry (Ni-Cd, Ni-MH, or Li-Ion).

How can I extend the lifespan of my battery?

Avoid deep discharges. For Li-Ion, recharge around 20-30% remaining. For Ni-Cd/Ni-MH, an occasional full discharge/charge can help maintain capacity.

What's the best way to store batteries when not in use?

Store at 40-60% charge in a cool, dry place (10-25°C). Keep away from moisture, heat, and direct sun. Remove the battery from the tool if idle for weeks.

Can I leave my battery on the charger overnight?

Modern chargers typically have auto shut-off and are safe. To maximize long-term health, remove the pack once it reaches 100%.

How do I clean and maintain my battery?

Keep contacts clean and dry. Wipe terminals with a dry cloth; avoid liquids and solvents. Inspect for cracks, swelling, or heat damage before use.

What warranty do you provide on replacement batteries?

All replacement batteries include a 12-month warranty and a 30-day money-back guarantee.

NiCd vs NiMH - Key Differences

Quick comparison to help customers choose the best replacement battery type.

Feature	NiCd (Nickel - Cadmium)	NiMH (Nickel - Metal Hydride)
Technology age	Older, legacy chemistryCommon in older tools.	Newer, improved chemistryModern standard for many replacement packs.
Memory effect	Higher - benefits from full discharge cyclesCan require occasional conditioning.	Much lower - easier to maintainNo strict full-discharge routine required.
Capacity / Runtime	Typically lower (shorter runtime)	Higher capacity - longer runtime
Self-discharge	Loses charge faster in storage	Holds charge longer when stored
Weight	Slightly heavier	Lighter
Environmental impact	Contains cadmium - toxic; restricted in many regions	More environmentally friendly

Recommendation For most users we recommend NiMH replacement batteries - they offer better runtime, less maintenance, and fewer environmental concerns. If your tool originally used NiCd, NiMH replacements are frequently compatible, but please check the voltage and label, or send us a photo for confirmation.
