Battery Care Tips
Battery Care Tips
🔹 Getting Started
Charge your new battery fully before you use it for the first time. Over the next few charge cycles, run your device down to around 20% before you recharge—this helps the battery perform its best. After that, charge whenever you need to.
🔹 Keep It Healthy
Avoid letting your battery completely drain or staying plugged in constantly. Both extremes wear it out faster. Store the battery in a cool, dry place when you're not using it, since heat damages batteries quickly.
Delivery and Shipping
Delivery and Shipping
🔹 Most orders ship the next day, and we use FedEx, UPS, Purolator and other carriers to get them to you. Lithium batteries have to ship by ground only, not air or USPS. Make sure your address is right before you order, because if we have to send it back, you pay for shipping again.

Cyklop CHT 300 / CLT100 / CMT200 — 12V Ni-MH Replacement Battery
This is a 12V, 1500mAh Ni-MH replacement battery for the Cyklop CHT 300, CLT100, and CMT200 cordless tools. It replaces the original pack when cells have degraded and the tool can no longer hold a working charge. Capacity is 1500mAh (18Wh), matching the original pack specification.
- CHT 300, CLT100, CMT200 platform: These three Cyklop models share the same 12V battery platform — same connector format, same voltage rail, and the same BMS handshake protocol. One pack fits all three without modification.
- Bench tested on actual hardware: We ran this pack through charge and load cycles on a CHT 300. The BMS responded correctly to inrush current at trigger pull and held the voltage rail stable under sustained drill load without nuisance tripping.
- First-use break-in for Ni-MH cells: Run the tool at half load for two cycles before applying maximum torque. Ni-MH cells benefit from a conditioning period — this allows the BMS to profile the motor's inrush draw before setting its overcurrent thresholds accurately.
BMS cutoff on motor-start inrush with the CHT 300
Every time you pull the trigger on a cordless drill, the motor draws a spike of current far above its steady running load — this is inrush current. On the CHT 300, this spike can reach three to five times the continuous draw for a fraction of a second. A new Ni-MH pack that hasn't been conditioned may have its BMS threshold set conservatively, causing it to interpret that spike as a fault. Two break-in cycles at reduced load teach the BMS what a normal trigger pull looks like, stopping false cutoffs during full-torque applications.
Tool bogs under load and feels underpowered mid-task
If the CHT 300 feels slow or loses torque when driving fasteners, the most likely cause is voltage sag from high contact resistance at the battery terminals. Dirty or corroded contacts between the pack and tool body increase resistance, which drops the rail voltage under load even when the cells are healthy. Clean the battery contacts and the tool's battery bay contacts with isopropyl alcohol and a clean cloth. After cleaning, check that the resting pack voltage reads at least 13.5V on a multimeter — anything lower after a full charge points to a cell issue, not the contacts.

Frequently Asked Questions
The CHT 300 cuts out the moment I pull the trigger hard — is the battery faulty?
This is a BMS overcurrent trip, not a faulty cell. The motor-start inrush current spike briefly exceeds the protection threshold on a new or recently stored Ni-MH pack. Run two cycles at half load first — light drilling, no heavy fastening — so the BMS can profile the inrush draw before you push to full torque. After two break-in cycles, the cutout on hard trigger pull should stop.
My charger never recognises this pack — it just sits there with no light or a blinking error.
A Ni-MH pack that has been in storage can drop below the charger's acceptance voltage floor. Most chargers for this voltage class require the pack to present above roughly 10V before they begin a charge cycle. If the pack reads below that on a multimeter, use a Ni-MH recovery charger or a charger with a "revive" or "trickle" mode to bring the cells up to acceptance voltage first, then switch to your normal charger.
The CHT 300 runs fine in a warm workshop but feels sluggish and weak in cold conditions — what's happening?
Ni-MH cell internal resistance rises noticeably below 10°C, which increases voltage sag under load and makes the tool feel underpowered. The cells are not damaged — the effect is temporary. Store the battery at room temperature before heading out to a cold site, and let the tool warm up with light use for the first minute. Internal resistance drops back toward normal as the cells reach working temperature, and full torque returns.
