Trojan T-105 → Canbat CDC224-6
Best Trojan T-105 Replacement Battery
The Trojan T-105 has been a workhorse 6V GC2 flooded battery for decades, but most buyers shopping for a replacement aren’t looking for another set of flooded cells to water and equalize — they want a battery that fits the same tray and runs the same job with less hassle. That’s the role the Canbat CDC224-6 is built for.
The CDC224-6 is a 6V 224Ah sealed AGM deep cycle battery in the GC2 group size, with the same footprint class as the T-105. It uses sealed deep-cycle AGM construction for strong cycling performance and dependable operation in GC2 deep-cycle applications. Because it is sealed VRLA, there is no watering, no acid weeping, and reduced terminal corrosion to manage over the life of the battery.
For most owners replacing a tired set of T-105s, the practical decision comes down to two questions: will it fit my tray and cables, and will my charger work with AGM. Both are covered in detail below.

Why Choose AGM Instead of Flooded Lead-Acid
For most owners replacing Trojan T-105 batteries, the appeal of a sealed AGM like the CDC224-6 isn’t a spec-sheet figure — it’s eliminating the recurring chores that come with flooded batteries:
- No watering. Electrolyte is absorbed in glass-mat separators and sealed in. Nothing to top up, no water levels to check every few cycles, no risk of damage from a cell running dry.
- Sealed, maintenance-free design. No cell caps to open, no equalization schedule to track, no specific gravity readings to take.
- Lower acid spill risk. AGM construction is sealed and spill-resistant under normal handling and tip-over scenarios that would leak a flooded battery.
- Reduced terminal corrosion. Without the constant acid misting and off-gassing of a flooded battery, terminals stay cleaner — less of the white buildup that eats connections and weekend afternoons.
- Cleaner operation. No acid weeping means no corroded trays, no baking-soda cleanups, no rusted hold-downs.
- Easier ownership. Install it, charge it, use it. For seasonal carts and RVs especially, the maintenance-free design makes off-season storage and shoulder-season use far simpler.
- Strong GC2 deep-cycle performance. The CDC224-6 is built for repeated deep discharge, not just standby duty — the right construction for the way T-105 owners actually use their batteries.
Flooded batteries still have legitimate strengths — they’re cheaper per unit upfront, they tolerate high-voltage equalization, and a well-maintained set delivers a lot of cycles. The honest trade-off is that those advantages depend on consistent maintenance. If you’d rather install batteries and not think about them again until they need replacing, sealed AGM is the more practical chemistry.
Will It Fit My GC2 Battery Tray?
The CDC224-6 is built to the GC2 group size and is a direct-fit GC2 replacement in many golf cart, floor scrubber, RV, and deep-cycle applications that currently use Trojan T-105 batteries. Two practical checks before you order:
- Tray dimensions and hold-downs. The CDC224-6 measures roughly 10.2″ long × 7.1″ wide × 9.96″ tall — close to the T-105 in length and width, and slightly shorter in height. That works in standard GC2 trays. Confirm your specific tray and hold-down clearance against the datasheet before ordering.
- Terminal type and cable reach. GC2 batteries use a few common terminal formats. Confirm your existing cable lugs match the CDC224-6’s terminal style; if they don’t, a simple adapter or new cable end resolves it.
- Weight. The CDC224-6 is approximately 67.2 lbs — a few pounds heavier than the T-105’s ~62 lbs. Not enough to be a concern for most golf cart trays or floor scrubbers, but worth noting for hand-lifting or weight-sensitive installations.
If you’re unsure whether the CDC224-6 will fit your specific equipment, send our team a model and we’ll confirm before you order.
Charger Compatibility
This is the one technical step worth doing carefully when moving from a flooded battery like the T-105 to a sealed AGM like the CDC224-6. Flooded and AGM batteries prefer slightly different charging profiles, and using the wrong profile long-term will shorten AGM life.
- Trojan T-105 is flooded lead-acid. Its charger profile typically uses higher absorption/equalization voltages that are appropriate for flooded chemistry but too aggressive for sealed AGM over time.
- Canbat CDC224-6 is sealed AGM. It needs a charger set to an AGM or sealed lead-acid profile, with absorption voltage and equalization behaviour appropriate for sealed batteries.
- Most modern golf cart and RV chargers support both. Many newer chargers have an AGM or sealed-battery setting selectable on the unit. Confirm your charger has this option, or that its default voltage stays within AGM-safe limits.
- Avoid long-term equalization charging on AGM. The high-voltage equalization step used on flooded batteries should not be run repeatedly on AGM. If your existing system runs an automatic equalization cycle, check that it can be disabled or that it’s already AGM-compatible.
Confirm before you order
If you’re not sure your charger has an AGM or sealed-battery setting, send our team the make and model. We’ll confirm compatibility — and recommend a Canbat AGM-compatible charger if your current unit won’t work cleanly with sealed batteries.

AGM vs Lithium as a T-105 Replacement
Some buyers replacing Trojan T-105 batteries also consider switching the entire bank to lithium. Both are valid paths — they fit different priorities.
Choose Canbat CDC224-6 AGM if:
- You want a maintenance-free GC2 replacement that fits the same tray
- You want familiar lead-acid charging behaviour with no system redesign
- You don’t want to rewire, reconfigure the charger, or upgrade the controller
- You want a sealed battery with no watering or equalization
- You want a lower upfront cost than lithium
Consider lithium if:
- Weight reduction is a top priority for the application
- You want longer cycle life and higher usable capacity per amp-hour
- Your charger, controller, and inverter are lithium-compatible (or you’re ready to upgrade them)
- You’re prepared for a larger system upgrade rather than a like-for-like swap

Common Trojan T-105 Replacement Questions
What is the best Trojan T-105 replacement battery?
The Canbat CDC224-6 is a strong replacement option for most T-105 applications. It’s a 6V 224Ah sealed AGM battery in the GC2 group size, matching the T-105’s voltage, footprint, and capacity within one amp-hour at the 20-hour rate — with no watering required, reduced spill risk, and reduced terminal corrosion compared with flooded chemistry.
Can I replace Trojan T-105 batteries with AGM batteries?
Yes, in most applications. A 6V GC2 AGM battery like the CDC224-6 fits the same tray and runs in the same series configuration as the T-105. The main check is charger compatibility: your charger needs an AGM or sealed-battery profile.
Will the Canbat CDC224-6 fit in the same GC2 battery tray?
In most cases, yes. The CDC224-6 is built to the GC2 group size and measures approximately 10.2″ × 7.1″ × 9.96″ — close to the T-105 in length and width, and slightly shorter in height. Confirm your specific tray, hold-down, and cable reach before ordering, especially in older or custom installations.
Do I need a different charger when switching from Trojan T-105 to AGM?
Not always a different charger — but your charger needs to support an AGM or sealed-battery profile, or to keep its voltage within AGM-safe limits. Most modern golf cart and RV chargers have this setting. Avoid running long-term equalization charging on AGM batteries. If you’re not sure, contact our team with your charger make and model.
Is AGM better than flooded lead-acid for golf carts?
For most owners, AGM is the more practical chemistry because it removes the watering, equalization, and corrosion-cleanup work that flooded batteries need to deliver their full cycle life. Flooded batteries still win on lowest upfront price and can be excellent when you’re willing to maintain them consistently. AGM is the better fit when you’d rather install the battery and not think about it again.
How many 6V batteries do I need to replace in a 36V or 48V golf cart?
The same number you have now: typically four 6V batteries for a 24V cart, six for a 36V cart, and eight for a 48V cart, wired in series. Configurations vary, so confirm your cart’s actual setup before ordering a full set.
Can I mix old Trojan T-105 batteries with new AGM batteries?
No — don’t mix old flooded batteries with new AGM batteries, and don’t mix old and new batteries of any chemistry in the same bank. Mixed banks pull the new batteries down to the level of the weakest cell and reduce overall life. Always replace the entire bank as a matched set.
Is lithium better than AGM for replacing Trojan T-105 batteries?
It depends on the application. Lithium is lighter, delivers more usable capacity per amp-hour, and cycles more times, but it costs more upfront and may require charger, controller, or wiring changes. AGM is the simpler like-for-like swap: same tray, same wiring, same series configuration, same lead-acid charging behaviour. For most owners doing a straight T-105 replacement without redesigning the system, AGM is the more practical choice.
