ENC-BO043 12V 1.5Ah / 2Ah 18Wh / 24Wh Ni-CD Power Tool Replacement Battery BAT043 for Bosch Drill BAT048 / BAT049 / BAT100 / BAT119 Cordless Drills

The ENC-BO043 replacement battery is fully compatible with the following Bosch drill battery models and catalog numbers:

✅ Two Capacity Grades, One Bosch 12V Platform
Direct replacement for the Bosch BAT043 OEM battery, offered in 1.5Ah (18Wh) for high-turnover rotation stock and 2Ah (24Wh) for about 33% longer run time per charge. Both grades share the same housing, latch geometry and weight class, and both cover the wider Bosch 12V drill battery family - BAT048, BAT049, BAT100, BAT119 and thirteen 2 607 335 xxx catalog numbers - so your team can mix and match packs and chargers across the fleet without sorting by capacity.

✅ Ni-CD Workhorse Chemistry: Deep Discharge, Cold Weather, Long Cycle Life
Nickel-cadmium cells are the classic jobsite chemistry for good reasons: they tolerate deep discharge without damage, accept a charge reliably at low workshop temperatures, and deliver stable 12V output under high-drain loads that drilling and driving demand. Premium high quality long-cycle Ni-CD cells are built for repeated charge-discharge cycles on busy jobsites, day after day.

✅ Faithful OEM-Spec Fit, Classic Black & Red Housing
The 10.65*8.7*11.1 cm black and red housing faithfully follows the original BAT043 dimensions and latch geometry for a true plug-and-play fit - click the pack into the drill, hear the latch engage, and the tool is ready to work. The high impact ABS+PC composite shell is anti-drop, dustproof and moisture resistant, and every pack passes 100% aging testing before shipment with a 12-month full quality warranty.

• ⭐ Bosch BAT043 Replacement - Direct drop-in fit, also covers the BAT048 / BAT049 / BAT100 / BAT119 family and thirteen 2 607 335 xxx catalog numbers without modification
• ⭐ 1.5Ah / 2Ah Dual Capacity Choice - Same housing and weight, about 33% more run time on the 2Ah grade; ideal for mixed rotation stock
• ⭐ Deep Discharge & Cold Weather Ready - Ni-CD chemistry tolerates deep discharge and charges reliably in low temperatures where other chemistries struggle
• ⭐ Memory Effect Managed - A full discharge and recharge every 10-15 cycles keeps capacity strong over hundreds of cycles
• ⭐ Rugged Jobsite Housing & Warranty - Black and red high impact ABS+PC shell, 100% aging tested before shipment, OEM private label available, 12-month full quality warranty

• ⚠ Do not disassemble, puncture, crush or modify the battery housing - internal cell damage may cause electrolyte leakage, overheating or fire. Ni-CD packs contain alkaline electrolyte: if electrolyte from a damaged pack contacts skin or eyes, rinse immediately with plenty of clean water and seek medical attention.

• ⚠ Keep battery terminals away from metal objects such as screws, nails, coins and keys to prevent accidental short-circuit - a particular risk in tool boxes and on jobsites. Do not expose the battery to high temperature, direct sunlight or open flame for extended periods, and never leave it inside a hot vehicle.

• ⚠ Only charge with a Bosch 12V Ni-CD compatible charger designed for the BAT043 battery family. Do NOT use a Li-ion CC/CV charger on this Ni-CD battery - the charging logic is completely different and may cause under-charge, overheating, permanent damage or safety hazards. If you plan to use a Ni-MH charger, confirm it explicitly supports Ni-CD packs at this voltage before charging.

• ⚠ Let the pack cool down after heavy use before recharging, and charge in a dry area at room temperature. To counter the memory effect, fully discharge the pack and recharge it every 10-15 cycles. For long-term storage, keep the pack in a cool dry place with a periodic top-up charge. Ni-CD packs contain cadmium and MUST be returned to an authorized battery recycling collection point in compliance with local regulations - never put them in household waste.
