Lead-Acid Storage Battery (VRLA / Gel)
Sealed lead-acid batteries for backup and simple off-grid systems.
- Rating
- Per cell / block model
- Versions
- VRLA AGM and gel types
Best for: Backup systems that cycle rarely, and budget off-grid kits.
- Low upfront cost
- Sealed, maintenance-free types
- Familiar to local technicians
- Gel version for deeper cycling
Lead-acid batteries remain useful where a battery is mostly on standby — alarm systems, small UPS units, or simple backup that cycles only during rare outages.
Lead-acid or lithium?
| Lead-acid (VRLA / gel) | LiFePO4 | |
|---|---|---|
| Upfront cost | Lower | Higher |
| Usable depth of discharge | Limited | Much deeper |
| Life with daily cycling | Short | Long |
| Weight | Heavy | Lighter |
| Heat tolerance | Life drops fast in heat | Better, still needs shade |
For daily solar cycling, lithium usually costs less over the life of the system. We say so when it applies, even if lead-acid would be the cheaper quote.

Frequently asked questions
Can I replace my lead-acid bank with lithium?
Often yes, but the inverter or charge controller must support lithium charging and ideally communicate with the BMS. We check your equipment first.
How long does a lead-acid battery last in a hot climate?
High temperature shortens lead-acid life considerably. Keep batteries in a shaded, ventilated space, and expect fewer years of service than the rating at 25 °C.
Do sealed batteries need maintenance?
No water topping is needed, but terminals, voltages and the charge settings should still be checked regularly.
Which certificates do your home storage products have?
It differs by model. Ask for the certificate list of the exact model with your quotation — we send copies, and you can check them with the issuing body. Lithium batteries always ship with a UN38.3 test summary.
Can I order a sample before a larger order?
Yes. Distributors and installers often start with one or two units to test with their inverters and customers. Lithium samples travel by sea or by an air service that accepts dangerous goods, so allow for that in the timeline.
