LG Chem Battery: Prices, Specs, Reviews & More
LG Chem is a long-term leading solar battery manufacturer renowned for the high performance and reliability of its products. Yet in 2022, LG Chem stepped down from the solar pv panels manufacturing business. We bet that’s not exactly what all LG Chem battery owners wanted to hear, to say the least.
Yet despite the exit, LG isn’t leaving its competitors too happy and is here to stay with its LG Chem RESU energy storage line-up.
Nevertheless, this situation leaves a good bunch of questions unanswered: “What happens to my LG battery warranty?”, “Can I still purchase an LG Chem battery in the UK?” or “Should I consider alternatives for LG solar panels?” after all.
In this article, we’ll shed some light on all of those questions and break down how you can benefit from the advanced features and capabilities of the LG Chem RESU line-up.
From 1 Feb 2024, 0% VAT will apply to retrofitted residential solar batteries.
Residential battery storage systems are now exempt from VAT in the UK, whether installed new, retroactively, or alongside a solar panel system.
Previously, 0% VAT was only available for domestic solar batteries when installed with a new solar panel system.
To find your solar battery match, you could read the reviews and then find an installer who could meet your requirements. However, this can take hours or days of your time. Moreover, that’s not a bulletproof way to find a certified company with the proper expertise.

What makes LG Chem solar batteries special?
LG Chem solar battery storage systems are quite popular with homeowners due to their reliability, cost-effectiveness, and backup protection during grid outages. These batteries offer several unique features that set them apart:
The LG Chem solar battery storage price is an attractive option for homeowners due to its price range between £2,200 and £7,600.
LG Chem batteries use lithium ions as the primary component of the battery’s electrolyte. A more advanced lithium nickel manganese cobalt oxide (NMC) technology contributes to the effectiveness of the LG Chem battery chemistry as it provides higher energy density and therefore allows more energy to be stored.
The RESU 10H Prime and RESU 16H Prime models are particularly notable for their performance and are considered compelling alternatives to the Tesla Powerwall in the UK. These batteries excel at storing excess energy generated during the day, reducing reliance on the grid and addressing power outages.
LG Chem battery specifications
LG Chem batteries show only a 16% capacity drop after the 3-year worth of cycles tested which makes the promised 10-year lifespan pretty doable.
All of the RESU models come with a 10-year warranty. Ever since LG stopped manufacturing solar panels, it still sells solar batteries, keeps all existing warranties valid and provides replacements, repairs or support whenever necessary.
