FAQs about the VARTA NiMH battery CP300H

What is the advantage of the prismatic form?

The flat, rectangular (prismatic) form allows for an extremely space-saving arrangement in devices where round cells (such as AA or AAA) would not fit optimally. This enables the design of especially slim and ergonomic enclosures, as is common in modern cordless phones or hand scanners.

For which applications is this battery suitable?

It is ideal for devices that require high capacity in a flat form factor. Main applications are cordless phones (DECT), mobile data collection devices, medical monitors and other professional handheld devices. It is usually used in multi-cell packs (e.g. with 2.4V or 3.6V).

How is this NiMH cell charged?

NiMH cells are typically charged with a constant current. Charging must be done using suitable charging electronics, which monitor the charging process and terminate it safely by methods such as -deltaV (voltage drop) or temperature monitoring to prevent overcharging.

What does "assembly" mean?

Since this is a single industrial cell, it is generally not used directly. During assembly, several cells are combined into a battery pack with the desired voltage and capacity (e.g. by welding), provided with protective insulation, and fitted with the appropriate connection cables and plugs.

How should this battery cell be disposed of?

Batteries must not be disposed of with household waste. As an industrial battery, it is subject to the regulations of the Batteries Act. Please take the used battery cell to the designated industrial or municipal return points to ensure proper and environmentally friendly recycling.
