Sell your GivEnergy battery, from the 2.6 to the 9.5
We buy every GivEnergy battery in the low-voltage range. If yours is a 2.6, 5.2 or 8.2 kWh, it's Gen 1. A 5.12 kWh is Gen 3, and a 9.5 kWh is Gen 2 or Gen 3. Each generation is a different height and weight and plugs in differently, so you can usually tell which one you've got.

Every GivEnergy battery we buy
The 5.2 kWh Gen 1 pack and the 5.12 kWh Gen 3 pack both get called a "5 kW battery". They're different packs, and the rating label says which you've got.
We also buy the high-voltage battery stacks. They're less common, so they don't have a page of their own.
Tell the generations apart by height, plugs and firmware
Start with the rating label. It names the model. If you can't see it, the pack's height and how its cables connect usually settle it.
- Giv-Bat 2.6 (Gen 1) The smallest GivEnergy pack, 299 mm tall and 35.5 kg. No breaker on the pack. A separate 100 A DC breaker sits on the wall beside it. Battery firmware in the app starts 30 (for example 3022).
- Giv-Bat 5.2 (Gen 1) 515 mm tall and 63 kg. No breaker on the pack. A separate 100 A DC breaker sits on the wall beside it. One bank of four DIP switches on the pack. Battery firmware in the app starts 30.
- Giv-Bat 8.2 (Gen 1) 669 mm tall and 103 kg. No breaker on the pack. A separate 100 A DC breaker sits on the wall beside it. Battery firmware in the app starts 30.
- Giv-Bat 9.5 (Gen 2) The tallest pack, at 800 mm and 110 kg. A 100 A DC breaker built into the pack. One combined power-and-data plug. Two banks of DIP switches (ID and master/slave). Battery firmware in the app starts 30.
- Giv-Bat 9.5 (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).
- Giv-Bat 5.12 (Gen 3) 338 mm tall and about 48 kg. Plug-in sockets marked A and B, a pre-installed isolator and a USB port for firmware. Battery firmware in the app starts 40.
If you're still not sure, pick "Not sure" for that pack on the form and add a photo of the label. We'll work it out from that.
The battery firmware number in the app tells a Gen 3 pack from an older one.
Packs of different generations can share an inverter once their firmware is new enough.
How tall and heavy each pack is
All six are 480 mm wide, so height is the quickest way to tell them apart on the wall.
| Model | Generation | Height | Weight | Depth of discharge |
|---|---|---|---|---|
| Giv-Bat 9.5 (Gen 3) | Gen 3 | 576 mm | 85 kg | 100% |
| Giv-Bat 9.5 (Gen 2) | Gen 2 | 800 mm | 110 kg | 100% |
| Giv-Bat 5.12 (Gen 3) | Gen 3 | 338 mm | 48 kg | 100% |
| Giv-Bat 8.2 (Gen 1) | Gen 1 | 669 mm | 103 kg | 100% |
| Giv-Bat 5.2 (Gen 1) | Gen 1 | 515 mm | 63 kg | 80% |
| Giv-Bat 2.6 (Gen 1) | Gen 1 | 299 mm | 35.5 kg | 80% |
The heaviest, the 9.5 Gen 2, weighs 110 kg. The form asks "Where is it fitted, and how do we get to it?", and we plan the collection from your answer.
The six packs side by side
Why same-size packs get different offers
We don't publish a price list. We price each pack on its own figures, using these six things.
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.
When two packs are the same size, the GivEnergy battery price turns mostly on health and cycle count.

"Batteries" is already pressed on the first step. After that, pick the tile for each pack, or "Not sure" if you can't tell.
What sizes do GivEnergy batteries come in?
There are six low-voltage packs across three generations. Gen 1 came in 2.6, 5.2 and 8.2 kWh, Gen 2 in 9.5 kWh, and Gen 3 in 5.12 and 9.5 kWh. An All in One holds 13.5 kWh of high-voltage battery in one cabinet with its inverter. We buy every one of them, and the high-voltage battery stacks as well.
Which GivEnergy batteries do you most want to buy?
The 9.5 Gen 2 and 9.5 Gen 3. We'll take them one at a time or as a matched set. We buy every other GivEnergy pack as well, from the 2.6 up.
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.

Selling GivEnergy batteries
Can I sell GivEnergy batteries of different generations together?
Yes. Put every pack on the form, whatever its generation, and you'll get one written offer for the lot. We price each pack on its own health and cycle count, then its generation and size. Packs of one generation that have run together are more useful to the next owner than odd ones.
Do you buy GivEnergy batteries without the inverter?
Yes. Choose batteries at the form's first step, then add each pack you're selling, one or several. The inverter stays where it is, and so do any packs you're keeping. On the day, our engineer isolates the system and disconnects only what you're selling.
