Rechargeable NiMH D-size battery GP 900DH 1.2V 900mAh

GP 900DH is a rechargeable NiMH D-size (Mono D) battery with a nominal voltage of 1.2V and a rated capacity of 900mAh. It is designed to replace single‑use D cells in devices that require larger cylindrical cells, offering a reusable power source for handheld and portable equipment. The NiMH chemistry provides reduced environmental impact compared with disposable alkaline cells and supports hundreds of recharge cycles when charged correctly.

Advantages

The GP 900DH delivers consistent voltage under moderate loads typical for flashlights, toys and radios, and it is compatible with standard D battery compartments. Rechargeability reduces the number of single‑use cells disposed of over time and lowers operating cost for frequently used devices. The nominal 1.2V output is suitable for most equipment designed for D cells and the sealed construction minimizes leakage risks associated with older cell types.

Suitable for

• Handheld flashlights and lanterns
• Children’s toys and electronic games
• Portable radios and small audio devices
• Camping and outdoor equipment requiring D cells
• Household devices with D battery compartments (e.g., clocks, remotes where applicable)

Key specifications

• Chemistry: Nickel‑Metal Hydride (NiMH)
• Nominal voltage: 1.2 V
• Rated capacity: 900 mAh
• Cell size: D (Mono D) cylindrical cell
• Rechargeable: yes, designed for multiple charge cycles
• Typical applications: moderate‑drain portable devices

How to use

Insert the GP 900DH cells into the device following the correct polarity markings. Charge the batteries with a charger compatible with NiMH D‑size cells and with an appropriate charging current for 900mAh capacity; follow the charger manufacturer’s instructions for charging times and modes. Do not mix rechargeable NiMH cells with primary (non‑rechargeable) batteries in the same device. Remove batteries from devices for extended storage and store them in a cool, dry place.

Recommendations

Use a modern NiMH smart charger that provides controlled charge and termination to maximize cycle life. For best performance, avoid deep discharge and follow the charger and device guidelines. Replace cells when capacity noticeably declines or if casing is damaged.
