How to check the age of golf cart batteries (and why it matters)

Short answer: Lift the seat. Most lead-acid golf cart batteries carry a date code on a sticker or stamped into the top edge: a letter for the month (A = January … L = December) and a number for the year (5 = 2025). "C5" means March 2025. Lithium packs show a manufacture date and serial on the case label. A pack older than four years is the single biggest deduction a buyer will make.

Where to look

1. Turn the key off and lift the seat (on most carts it hinges up from the front; some have a latch at the back).
2. Look at the top of each battery. Date codes are usually on a small sticker near a terminal or stamped into the plastic on the top edge.
3. Photograph every battery — buyers want to see that all units are the same age. Mixed ages usually mean the pack has been "patched" and the whole set is on borrowed time.

Reading the codes

Other brands follow one of these two systems. If you only see a long alphanumeric string, photograph it — we can usually decode it.

What age means for value

• 0–2 years: no deduction. Say so in your listing.
• 2–4 years: small deduction; a load test tells the real story.
• 4+ years: expect the full cost of a new pack to come off the price. The cart still sells — the number is just honest about what the next owner is going to spend.

Quick health checks you can do

• Does it complete a full round (or your normal loop) without the last few holes feeling slow? Fade is the first sign.
• Are the terminals white or green with corrosion? Clean-able, but it signals neglect.
• Water levels on flooded batteries: plates should be covered. Dry cells mean damage.
• After a full charge, does the meter drop quickly under load? Tired pack.
