LiFePO4 vs Lead-Acid Solar Batteries: Compare a Written Quote
Decision details
Fits if: Buyers comparing solar-battery offers that name different chemistries or models.
Main drawback: No comparable lead-acid price or equivalent cycle-life evidence is established on this page.
Compare: Exact chemistry and SKU, nominal and usable capacity, full installed price, and warranty terms including capacity/cycle conditions.
Do not choose by chemistry name alone
A LiFePO4 or lead-acid label is not enough to compare two offers. Ask the manufacturer and installer to identify the full model, the chemistry stated for that model, nominal and usable capacity, and the warranty document that applies. The evidence reviewed here does not provide a like-for-like comparison of cycle life or service life between the two chemistries.
| Listed model | Capacity | Displayed price | Comparison limit |
|---|---|---|---|
| Sungrow SBR | 5 kWh | RM7,999 [source] | Trexon advertised installed price; not a market price or current guarantee |
| Sungrow SBR | 10 kWh | RM14,999 [source] | Different SKU/capacity; not a direct comparison with lead-acid |
| Sungrow SBR | 15 kWh | RM21,999 [source] | Seller-displayed price; confirm current price and scope |
| Huawei LUNA S1 | 5 kWh | RM9,999 [source] | Different model and capacity from other rows |
| Huawei LUNA S1 | 10 kWh | RM17,999 [source] | Different model and capacity from other rows |
These figures show what one seller displayed for named models; they do not establish a price for all batteries or prove a cost difference between chemistries. Comparable lead-acid pricing and equivalent cycle-life terms are not established here.
Quote checklist
Ask each seller to identify the exact chemistry and SKU, nominal and usable capacity, battery and installation prices separately, any additional equipment, product and workmanship warranties, and claim conditions. For lifespan, ask for the model-specific term, cycle count if stated, depth-of-discharge limit and remaining-capacity threshold in the document. Do not transfer a lifespan or capacity figure from a different model.
Compare offers only after their scope and usable capacity are written on the same basis. If those details are missing, ask the provider to complete the quote; this page does not contain enough evidence to choose a chemistry for your site.
| Quote item | Offer A | Offer B |
|---|---|---|
| Exact chemistry, make, model/SKU and quote date | ____ | ____ |
| Rated and usable capacity (kWh), warranty capacity condition | ____ | ____ |
| Battery price; inverter/controls and other required equipment | RM ____ | RM ____ |
| Installation, wiring, protection, commissioning and exclusions | RM ____ / ____ | RM ____ / ____ |
| One-time total installed price | RM ____ | RM ____ |
| Product/workmanship warranty, claim conditions and responsible party | ____ | ____ |
| If usable kWh is documented: total ÷ usable kWh | RM ____/usable kWh | RM ____/usable kWh |
The last row is only a price-per-usable-capacity screen. It does not compare lifetime, cycle performance, compatibility or backup capability. Keep any missing capacity or scope marked “not stated”; do not divide by nominal capacity as if it were usable or infer a chemistry winner.

Frequently asked questions
LiFePO4 or lead-acid: which is better?
The evidence on this page does not establish a general winner or a like-for-like cycle-life comparison. Request documents for the exact model, usable capacity and warranty terms before comparing.
A lead-acid battery failed after about two years. Can this page explain why?
Not from the age alone. To investigate that specific case, give the seller or service party the exact model, installation date, reported fault and available installation/maintenance records; ask for a written inspection finding and the warranty clause or remedy that applies. This page does not diagnose the cause or infer a general lifespan for either chemistry.
What battery prices have been displayed?
Trexon’s page dated 17 March 2026 listed Sungrow SBR at RM7,999 for 5 kWh, RM14,999 for 10 kWh and RM21,999 for 15 kWh; Huawei LUNA S1 at RM9,999 for 5 kWh and RM17,999 for 10 kWh [source] [source] [source] [source]. These are one seller’s displays for different models, not current quotes or lead-acid prices.
What details should I compare?
Ask for the exact chemistry and model, nominal and usable capacity, full price and installation scope, and the warranty document with its claim conditions.
Does this page show how long each chemistry lasts?
No. The evidence here does not provide an equivalent cycle-life measure for LiFePO4 and lead-acid. Use the documents for the exact model offered.
