Cross-reference guides

OEM and competitor lookups. Always confirm voltage, group size, terminals, and dimensions before substituting.

OEM / competitor cross-reference

Match common manufacturer numbers to GMI equivalents. Electrical fit is not a drop-in guarantee.

Case dimensions and typical applications by BCI group.

PDF Example Download
OEM / competitor Their number GMI equivalent Notes
Trojan T-105 GMI-GC2-xxx Confirm flooded vs AGM and watering requirements.
US Battery US 2200 XC2 GMI-GC2-xxx Check terminal orientation and tray height.
Crown CR-220 GMI-GC2-xxx Verify reserve minutes at the equipment load.
Interstate DCM0035 GMI-DC12-xxx Deep-cycle marine / RV group comparison.

Example cross-reference only. Update numbers from your current interchange file.

03

Application guides

Selection notes by duty cycle. Duplicate a card for each additional guide.

04

Charging & maintenance

Charge profiles and charger matching. Use the datasheet when values differ.

Charging profile guide

AGM, gel, and lithium bulk / absorb / float ranges, plus temperature compensation.

Charger compatibility chart

Bank size vs recommended charger family.

PDF Example Download
Chemistry Bulk / absorb (12 V) Float (12 V) Notes
AGM 14.4–14.7 V 13.5–13.8 V Temperature compensate ~ −18 mV/°C per 12 V block.
Gel 14.1–14.4 V 13.5–13.8 V Do not use an AGM-only “boost” profile on gel.
Flooded 14.6–14.8 V 13.2–13.5 V Equalize only when the manufacturer specifies it.
LiFePO4 14.2–14.6 V Often none / 13.4–13.6 V Use a lithium profile. Do not equalize.

Example setpoints. Replace with your published charge tables.

05

PDF Example Download
Do Do not
Wear eye protection and follow the SDS for the chemistry you are handling. Do not mix old and new batteries, or different chemistries, in the same series string.
Torque terminals to the datasheet value and use the specified hardware. Do not charge lithium on an AGM/gel equalize or boost profile.
Fuse each string as close to the positive terminal as practical. Do not install flooded batteries in an unvented living space.

FAQ

Short answers. Edit the copy; duplicate a details block to add a question.

Can I mix AGM and lithium?

No. Different charge voltages, internal resistance, and BMS behavior. Run one chemistry per bank.

How do I pick a charger?

Match chemistry first, then bank Ah. A common starting point is about 10–20% of Ah for lead-acid and the datasheet charge current for lithium.

Where are PDFs hosted?

Upload files in BigCommerce (WebDAV or Commerce files) and replace each example href with the public URL, typically under /content/.

How often is this page updated?

Update the “Last reviewed” date in the header when you swap files. Specs on the live datasheet always override this page.
