Sell your GivEnergy 8.2 kWh battery
The GivEnergy 8.2 kWh battery is the biggest Gen 1 pack, 669 mm tall and 103 kg on the current datasheet, and of the low-voltage packs only a 9.5 Gen 2 weighs more. We buy it, and that weight is what we plan around on collection day. Take up our written offer, then our engineer disconnects it. Collection from your address in mainland England and Wales is free of charge.

Telling an 8.2 from a 9.5 Gen 2
- 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.
Both packs here are our drawings, sized to one scale, because we have no photo of an 8.2 on file. The taller pack is the 9.5 Gen 2, 800 mm, which has its DC breaker inside the case. An 8.2 has none inside. Its breaker is wired in separately, on the wall.
GivEnergy has published three sets of figures for it. A sheet dated May 2022 gives 94 kg and 620 mm, the Gen 1 battery manual 94 kg at 669 mm, and the current datasheet 103 kg at 669 mm. We print the newest.
Inverters that take an 8.2
| Inverter | Works with an 8.2? | Notes |
|---|---|---|
| Hybrid inverter (Gen 1) | Yes | With a separate 100 A DC breaker. |
| Hybrid inverter (Gen 2) | Yes | With a separate 100 A DC breaker. |
| Hybrid inverter (Gen 3) | Yes | Ring terminals and a DC breaker of at least 100 A. |
| 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. |
If its inverter is leaving with it, a hybrid or the AC Coupled, add it to your form and we price them separately.
An 8.2 is rated to 100% depth of discharge
That's the figure on GivEnergy's current datasheet. The current sheets for the 2.6 and 5.2 give 80%, so of the three Gen 1 sizes, the 8.2 is the one rated to use all of its 8.2 kWh.
How an 8.2's offer is set
We don't publish a price list. On an 8.2, as on every pack, health and cycle count lead, and its size counts for it.
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.
If the app's battery screen shows its cycle count, a figure the label can't give us, a screenshot helps.
List the 8.2 and anything going with it
Choose "Inverter and batteries" when the inverter goes too, or keep "Batteries". Every pack row starts as an "8.2".
What's a used GivEnergy 8.2 kWh battery worth?
Two figures from the pack's own records count most, its cycle count and the capacity it has kept. Cell balance comes next, then whether it ran as a matched set. We don't publish a price list. You get a written offer for your 8.2 by email. A working 8.2 is also checked remotely before collection day.
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.

Smaller Gen 1 sizes, with the 9.5 Gen 2
Selling an 8.2
Which generation is the GivEnergy 8.2 kWh battery?
Gen 1. It's in GivEnergy's Gen 1 battery manual alongside the 2.6 and the 5.2, and the app shows its battery firmware as a number beginning 30. A GivEnergy datasheet for it is dated May 2022, and it was later replaced by the 9.5 Gen 2.
How heavy is a GivEnergy 8.2 kWh battery?
GivEnergy's current datasheet puts it at 103 kg, though its Gen 1 manual says 94 kg. Say on the form how it's mounted and what lies between it and the road. We plan the lift from what you tell us, once our engineer has disconnected it.
Do you buy an 8.2 with an AC Coupled inverter?
Yes, together or on their own. GivEnergy pairs its Gen 1 packs with the AC Coupled. On the form, choose "Inverter and batteries", then the "AC Coupled" tile for the inverter, and pick "8.2" for each pack.
