New compatible A2389 battery for Apple MacBook Air 13" M1 A2337

Premium ternary battery for MacBook

Looking for a battery that lasts more than just a few months? Our batteries are not just cheap replacements.

This battery uses ternary lithium-ion cells (NCM) that combine three key metals – nickel, cobalt and manganese. Thanks to this advanced chemistry, it offers higher energy density, longer service life and more stable performance than most commonly available replacement batteries on the market.

This is not a standard replacement – it is a battery whose design and performance parameters are close to the original, and it often even surpasses it in battery life and thermal management.

• Higher cell quality than conventional batteries with purely cobalt-based or cheaper LFP chemistry

• Long-term stable capacity that does not drop quickly after just a few dozen cycles

• Better chemistry = better safety and less heating

• Optimised for use in a MacBook, including electronics for correct charging and communication with the system

We recommend it to anyone looking for a reliable battery with a long service life – from everyday users to IT technicians and service centres that do not want to take risks with cheap alternatives of uncertain origin.
