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.

Spit HDI 244 / HDI 220 — 12V Ni-MH Replacement Battery
This is a 12V, 1500mAh Ni-MH replacement battery for the Spit HDI 244 and HDI 220 cordless hammer drills. It slots into both models, which share the same battery platform and connector format. Capacity is 1500mAh (18Wh), matching the original specification.
- HDI 244 and HDI 220 platform fit: Both drills run the same 12V battery rail and use the same slide-in connector and BMS handshake. One battery covers both tools without any modification.
- Bench tested on actual hardware: We ran this pack through repeated motor-start cycles on the HDI 244. The BMS held stable through trigger-pull inrush spikes and did not trip at normal drill speeds. Cell temperatures stayed within safe limits across sustained driving sequences.
- Break-in for inrush profiling: On first use, run the drill at half load — light drilling or slow-speed fastening — for two full charge-discharge cycles before pushing maximum torque. This lets the BMS log the motor's inrush current signature and calibrate its overcurrent threshold accordingly, reducing nuisance cutoffs during heavy use later.
BMS cutoff on HDI 244 motor-start inrush surge
When you pull the trigger hard on a fresh or storage-recovered Ni-MH pack, the motor draws a sharp current spike that can exceed the BMS overcurrent threshold before the drill reaches running speed. This is especially common if the pack has been sitting discharged — cell voltage is low, internal resistance is elevated, and the BMS is more sensitive to sudden load. The fix is to condition the pack with two lighter-load cycles first, as described in the break-in tip above. After that, the BMS threshold adjusts and normal trigger pulls stop tripping it.
Tool bogs under load and loses torque mid-fastening
If the HDI 244 starts strong but loses speed or torque as the screw sinks, the usual cause is voltage sag from high contact resistance at the battery rail — not a dead cell. Check the slide contacts on both the battery and the drill body for oxidation or debris; even light surface corrosion adds enough resistance to drop the voltage rail under load. Clean the contacts with a dry cloth or fine emery paper and retest. If sag persists after cleaning, measure open-circuit voltage on a full charge — it should read at least 13.2V for a healthy 12V Ni-MH pack.

Frequently Asked Questions
My Spit HDI 244 cuts out the instant I pull the trigger hard — is the battery dead or is something else happening?
This is almost always a BMS overcurrent trip, not a dead pack. The motor draws a sharp current spike at trigger pull, and if the battery is new from storage or recently discharged, the elevated internal resistance pushes that spike past the BMS cutoff threshold. Let the pack complete two full charge-discharge cycles at light load first — light drilling, no masonry. After that conditioning, the BMS profiles the motor's inrush draw and the cutoffs stop.
The charger never does anything when I put this new pack in — no light, no fan, nothing.
Ni-MH chargers have a minimum cell voltage they check before starting a charge cycle. If the pack sat discharged in a warehouse or in transit, the cells can drop below that acceptance threshold — typically around 1V per cell. Some chargers will simply ignore the pack rather than blink or fault. Try leaving the pack in the charger for 15–20 minutes; some units will trickle-charge at a low rate to recover the cells before switching to normal charge. If the charger still shows nothing after 20 minutes, measure pack voltage — if it reads below 10V for a 12V Ni-MH pack, the cells need a slow recovery charge before the charger will accept it.
The HDI 220 drills fine when warm but feels weak first thing in the morning on a cold site — is this the battery?
Yes. Ni-MH internal resistance rises significantly in cold conditions — below about 5°C, the cells deliver noticeably less current under the same load. The drill won't cut out, but torque and speed drop because the voltage rail sags harder when resistance is up. Keep the battery in a jacket pocket or tool bag overnight rather than leaving it in the drill on a cold van floor. A 15-minute warm-up at room temperature before use is enough to bring internal resistance back down to normal operating range.
