This page collects the 12V face of XD Battery’s deep-cycling series — the blocks engineered for repeated deep discharge rather than float standby. The family’s logic is capacity tiering on a shared plate discipline: the 100Ah storage block for standard banks, the 200Ah high-capacity block for halved string counts, and the 250Ah custom-logo block for distributors building their own branded line. All are sealed lead acid designs in the deep-cycling series; documented models carry three-year warranties.

Living with deep-cycle blocks
Three operating rules decide whether a deep-cycle bank reaches its design life. Size for the discharge you actually take: routine sizing near 50% depth of discharge is the standard bargain between capacity bought and cycles delivered. Recharge promptly and fully: a bank left sitting discharged sulfates, and no plate design forgives chronic undercharge. And keep the bank homogeneous: one model, one age, one batch where possible, because in a series string the weakest block sets the string’s capacity and in parallel it sets the imbalance. The deep-cycle category page covers the engineering in more depth; the solar deep-cycle page applies it to PV systems specifically, charge controllers and all.
For buyers comparing chemistries on this site: the gel versions of this duty add heat tolerance and spill-proofing at a premium; the OPzV cells move the same cycling job into 2V format for decade-scale stationary banks. The 12V deep-cycle block remains the value centre of the range — which is why it anchors the solar and marine application pages across this site.
How many cycles should I expect?
Cycle life is a function of discharge depth, temperature and recharge discipline; the honest figure for your duty cycle comes from the model datasheet. Tell us your daily depth of discharge and we will quote against it rather than against a headline number.
Can these charge from a vehicle alternator?
With a suitable DC-DC charger or split-charge setup rated for deep-cycle profiles, yes — RV and marine installations do it routinely. The marine page covers the arrangement.
Do you sell matched sets for banks?
Yes — bank orders are picked as matched sets. State the system voltage and block count in the inquiry.
Matching the charger to the bank
A deep-cycle bank’s life is co-authored by its charger. The profile must complete a full absorption phase at the correct voltage for the battery’s construction, return the bank to full charge after each discharge cycle, and — in solar service — be fed by an array sized to finish the job on an average day. Temperature compensation matters wherever the bank’s room swings with the seasons. When ordering blocks for an existing system, tell us the charger or controller model: confirming the profile match at quotation is free, while discovering the mismatch in year two costs a bank.
The deep-cycle families publish their certification names per model — CE, UL, ISO 9001 and RoHS on the documented models, within the wider TUV/UL/CE/CSA/CEC/JET set the company publishes — certificates available upon request, with the model-level marks confirmed on each quotation.
