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.

Custom Battery Pack SC1700HT — 6V Ni-MH Replacement Battery
This is a 6V 1700mAh Ni-MH replacement battery pack for emergency lighting systems and backup power applications. It replaces OEM part SC1700HT in units that depend on sustained voltage delivery during power-loss events. Capacity is 1700mAh (10.2Wh) — confirmed from product data, not estimated.
- Emergency lighting compatibility: These packs share a 6V nominal rail and a standardised cell arrangement that most emergency lighting charge circuits expect. The BMS handshake on this pack aligns with charge controllers that monitor cell voltage rather than pack authentication codes.
- Bench tested on actual hardware: We cycled this pack through charge and discharge on a 6V Ni-MH compatible charge controller. The BMS held cell balance across the full charge arc, and voltage stayed within the expected 6.0–7.2V window from trickle-in to top-off.
- First-use cycle for emergency packs: Emergency lighting units often store a pack for months before the first real event. Run one full charge-discharge cycle immediately after installation so the charge controller builds an accurate capacity baseline against the new cells.
Pack running below rated voltage on first installation
Ni-MH packs ship at storage voltage — typically 5.4–5.8V rather than the 6V nominal. Emergency lighting units that check pack voltage at startup may flag a low-battery condition or refuse to switch to standby mode. This is not a fault with the pack. Connect the unit to mains power and allow a full charge cycle before testing. After charge, resting voltage should sit at 7.0–7.2V across the pack.
Pack not reaching full charge on the first cycle
Some emergency lighting charge ICs limit current on the first cycle when they detect a pack starting from storage voltage — they treat the low initial voltage as a sign of damage and throttle the charge rate. This clears after one full cycle. If the charge indicator still shows incomplete after a second cycle, check that the charge controller's delta-V cutoff threshold matches Ni-MH chemistry — some units default to NiCd settings, which terminate charge earlier.

Frequently Asked Questions
My emergency light shows a fault code right after I swapped the battery pack — it wasn't doing that before.
The charge controller read the pack at storage voltage and flagged it as a failed cell. Connect the unit to mains and let it complete a full charge cycle — do not interrupt it. Once the pack reaches 7.0–7.2V resting voltage, power-cycle the unit and the fault should clear. If the fault persists after a full charge, check the connector seating before assuming a pack fault.
The battery feels warm during the first charge — is that normal for this pack?
Ni-MH cells generate more heat during the conditioning cycle than on subsequent charges because the charge controller is pushing current into cells that aren't yet fully formed. Warm to the touch is normal; hot enough to be uncomfortable means the charge IC isn't detecting the delta-V peak correctly and is overcharging. Check that the charger is rated for Ni-MH — a NiCd-only charger will not terminate at the right point and will push excess heat into the pack.
The emergency light runs the pack flat too quickly after the swap — capacity seems lower than the old pack.
A new Ni-MH pack often delivers below its rated 1700mAh for the first one or two cycles because the cells haven't been fully conditioned. Run two full charge-discharge cycles before drawing conclusions about capacity. If output is still noticeably short after conditioning, verify the charge controller's top-off voltage — if it's cutting charge at 6.6V instead of letting the pack reach 7.0–7.2V, the pack is never starting from a full state.
