Sell your GivEnergy 9.5 Gen 3 battery
The GivEnergy 9.5 Gen 3 (9.5 kWh) is the pack we most want. We'll take one or a set. You get a written offer by email, and if you take it, our engineer disconnects the pack and we collect it free across mainland England and Wales.

How to tell your 9.5 is a Gen 3
- 576 mm tall and 85 kg. That's much shorter than a 9.5 Gen 2, and 25 kg lighter.
- Plug-in sockets marked A and B instead of bolted terminals, a built-in isolator and an on/off button on the right side.
- Model code GIV-BAT-9.5-G3 on the nameplate (right-hand side).
- Battery firmware in the app starts 40 (for example 4009).
The pack beside it, at the same scale, is a 9.5 Gen 2. It holds the same 9.5 kWh but stands 800 mm tall. GivEnergy's firmware notes mention the 9.5 Gen 3 from January 2024.
Published figures for this pack differ. The datasheet and the manual both say 576 mm and 85 kg, so we use those. You can check GivEnergy's Gen 3 datasheet and the Gen 3 installation manual yourself.
What a 9.5 Gen 3 works with
| Inverter | Works with a 9.5 Gen 3? | Notes |
|---|---|---|
| Hybrid inverter (Gen 1) | Yes | Lug-to-plug cable. |
| Hybrid inverter (Gen 2) | Yes | Lug-to-plug cable. |
| Hybrid inverter (Gen 3) | Yes | Plug-to-plug cable. |
| AC Coupled inverter 3.0 kW | Yes | |
| All in One | No | GivEnergy doesn't list it. The All in One runs its own 307 V battery. |
| All in One 2 | No | GivEnergy doesn't list it. The All in One 2 runs its own 307 V battery. |
The two rules on mixing generations only matter if you sell part of a mixed set and keep the rest.
Adding a 9.5 Gen 3 to the form
The form's first step asks what you're selling. For one 9.5 Gen 3 or several, choose "Batteries". If the inverter is going too, choose "Inverter and batteries" instead, and the form then asks which inverter you have.
One inverter takes up to five low-voltage packs, one master and four slaves. If you've got more than five, pick "6 or more". List every pack you're selling on the one form, and use the notes to say which of them have run together as a set.
A short Gen 3 pack is the 5.12 Gen 3
The other low-voltage Gen 3 pack we buy is the 5.12 Gen 3. It has the same plug-in sockets marked A and B, but it's only 338 mm tall and holds 5.12 kWh. The model code on the nameplate tells you which one you've got.
What counts on a 9.5 Gen 3
We don't publish a price list. A 9.5 Gen 3 is judged first on its health and how many cycles it has run, and its generation and size count in its favour.
State of health
The battery management system records how much of its original capacity is left. For most packs it's the figure that matters most.
Cycle count
A high count is fine if the pack's health is good.
Generation and size
A 9.5 kWh Gen 3 pack is worth more than a 2.6 Gen 1. The rating label tells us which you have.
Cell balance
How closely the cells match. If they're far apart, the pack needs work before anyone can use it again.
A matched set
Packs of one generation that have run together are more useful to the next owner than odd ones.
Where it's been fitted
A garage or a loft is kinder than an outside wall. If the terminals or casing are weathered, say so on the form.
A Gen 3 from a pair that ran together counts for more in a used GivEnergy pack's price than one that sat beside older packs.
Tell us about your 9.5 Gen 3
Pick "Batteries", then "9.5 G3" for each pack.
What's a used GivEnergy 9.5 Gen 3 battery worth?
That mostly comes down to how much of its capacity it still holds and how hard it's worked. After that, whether it's part of a set and what state the casing and sockets are in. We don't publish a price list. Send the form, with a screenshot of the app's battery details if you have one, and we'll email you a written offer. If it's working, we confirm its health with a remote check, down to cell level, before we collect.
How do you collect a 9.5 Gen 3?
Our engineer isolates the system and takes the pack off the wall, then we load it. We collect within 7 days of booking, usually within 24 hours, and confirm the date by email. A 9.5 Gen 3 weighs 85 kg, so tell us about stairs or tight corners on the form and we'll plan the lift.
Before we collect
- For a working battery, we email you a link to a small app. You run it on a computer on the same network as your system.
- Then we run a state-of-charge calibration from our end. It reads each cell and tells us the battery's state of health and cycle count.
- If the kit differs from your description, on the check or on the day, we may requote or withdraw our offer, and you're free to walk away at no cost.
Please don't take it off the wall yourself
A low-voltage GivEnergy pack runs at 51.2 V DC with real fault current behind it. A high-voltage stack runs well above that, and an All in One at around 307 V. Our engineer isolates the system before anything is moved. If your installer has already disconnected it, say so on the form.

Its look-alike and the other Gen 3 pack
Selling a 9.5 Gen 3
Do you buy a 9.5 Gen 3 that was added to an older system?
Yes, and we'll buy it on its own or with the older packs. GivEnergy's 5.12 manual has a Gen 3 added to Gen 1 or Gen 2 packs run as the master, though its firmware note 3017 says "G3 and G1 can be mixed in any Master/Slave combination". Put every pack on the form, so the offer covers what you want to sell and we know what stays behind.
Can I sell one 9.5 Gen 3 and keep my other packs?
Yes. If another Gen 3 pack stays alongside Gen 1 or Gen 2 packs, each pack's firmware has to date from May 2024 or later. GivEnergy's own documents don't agree on which pack should lead.
