Where to Buy Trojan Batteries in the Philippines

Trojan reaches Philippine buyers through one named master distributor. This page covers how to buy through that channel and the questions specific to lead-acid — for whether Trojan or lithium is the right chemistry for your system, read the review first, and see lithium vs lead-acid for the underlying comparison.

The distributor: YHI Philippines Inc

YHI Philippines Inc is a subsidiary of YHI International Limited, a Singapore-headquartered distributor of automotive and industrial battery products with operations across multiple countries. We confirmed this directly: yhiph.com is live as of August 2026, carries a dedicated /trojan page, and its Batteries page states “Trojan’s advanced battery designs are long-lasting, clean and built to withstand the challenges of harsh environments” alongside a link through to the Trojan-specific page.

YHI Philippines also distributes tires, wheels and lubricants — batteries and solar are one division among several, not its sole business. Its site lists a dedicated Batteries and Solar sales team with named contacts and direct phone numbers on its dealers page, which is more contactable detail than most distributors on this site publish.

How to actually buy it

1. Contact the Batteries and Solar sales team directly through yhiph.com/dealers for a quote — named individuals with mobile numbers and emails were listed there when we checked.
2. Through an installer or off-grid systems builder who works with flooded or AGM lead-acid banks, since Trojan’s typical buyer is building or maintaining an existing lead-acid system rather than starting from scratch with lithium.

Trojan is priced above generic deep-cycle lead-acid, not as a budget option. We have no verified Philippine retail price list to quote — get an itemized quote from YHI Philippines or your installer, and compare it on peso per usable kWh, not sticker price, against the ₱13,000–23,000 per usable kWh that LFP batteries run here — see our battery price guide and how to size a solar battery for why that comparison matters more for lead-acid than for any other chemistry on this site.

The warranty path, concretely

YHI Philippines’ site did not show a published Trojan-specific warranty claims page in our check. Before paying:

• Get the specific warranty term for the exact model (flooded, AGM or gel all differ) in writing from YHI Philippines or your installer.
• Ask whether YHI Philippines or your installer handles the claim directly, and what proof of purchase and installation date you’ll need.
• Confirm whether maintenance requirements (watering, terminal checks) are a condition of the warranty remaining valid — lead-acid warranties commonly exclude damage from neglected maintenance in a way lithium warranties don’t.

See warranties explained for what a warranty term is worth without a documented claims process.

Buying lead-acid is a different conversation than buying lithium

Every other brand on this site’s “where to buy” series is lithium. Trojan isn’t, and that changes what you should ask:

• Depth of discharge. Lead-acid should not be routinely discharged past 50% if you want rated life. Ask your installer to size the bank for that, not for LFP’s 80-95% usable range.
• Ventilation. Flooded Trojans off-gas when charging and need a ventilated, shaded location — not a sealed indoor cabinet. Confirm your installer has planned for this.
• Maintenance commitment. Flooded cells need watering and terminal checks. If that realistically won’t happen, ask about Trojan’s AGM or gel lines instead, which remove the watering task at some cost to price and cycle life.
• Existing system compatibility. Trojan makes the most sense retrofitted into or added to an existing lead-acid bank and charge controller, not paired fresh with a modern lithium-oriented hybrid inverter.

Grey-market risk

Lead-acid deep-cycle batteries see less counterfeiting than lithium packs, but generic “Trojan-style” batteries and rebadged imports do circulate. Buying through YHI Philippines or an installer who can show that relationship is the practical check — see how to avoid solar scams.

The bottom line

YHI Philippines Inc is a real, currently active, and unusually contactable Trojan channel — confirmed on its own live site with named sales staff in August 2026. The chemistry question matters more than the channel question here: confirm with your installer whether lead-acid is genuinely the right call for a system that cycles daily, per our lithium vs lead-acid guide, before locking in a Trojan quote.
