Compatible replacement battery - New life for your Medtronic / Physio-Control medical device. Replacement part with high quality and the best price/performance ratio. Reliable functionality and full compatibility with your medical device. Precise workmanship for problem-free installation in your device. CE & RoHS - fulfills all operational safety requirements. No memory effect. Highly modern lithium-ion cells for optimum device performance. Lithium-ion batteries are among the most powerful rechargeable batteries. Compared to NiMH batteries, they are characterized by low self-discharge and a higher energy content. They are not subject to a memory effect and are low-maintenance, as they do not require regular discharging. Li-ion batteries have a long service life if stored correctly, as they are durable and have a high number of possible charging cycles. Li-ion batteries are used in mobile devices with high energy requirements such as smartphones, notebooks, cameras, and power tools. These batteries are also used in RC modeling and photovoltaics. Practical note: If the capacity of our lithium-ion replacement battery is significantly higher than the original battery (from 1000mAh and higher), the replacement battery may be heavier, deeper, and thicker than the original battery. It may therefore protrude slightly. Data sheet item number 888203223. Item condition: New. Scope of delivery: 1x battery. Battery technology: Lithium-ion. Capacity: 7800 mAh. Voltage: 11.1 V.
